Albert E. F. Moonefchicago, Ill., assig nor to, Orenda Corporation, Chicago, 111., a corporation of Illinois Application November 1, 1930. Serial No. 492,740. 10 Claims. o1. 154-3 1) The invention relates to apparatus formaking packing material and has reference in particular to a method and means'for forming packing material having super-cushioning properties.

An object of the invention is'to provide a machine having improved means for efliciently forming a pluraltiy of grooves in a continuously moving sheet of paper longitudinally thereof, by

initially gathering said sheet" centrally of the same by forming offsets in the plane of the sheetand subsequently utilizing the offsets to form the grooves; to provide improved means including: a series of drums'to successively form embossed areas on the sheet as it is received from the gathering rolls and to apply tothe side of'the sheet opposite the embossed areas a thin'coating of an adhesive; to provide'means including a second series of drums to press together the embossed sheet and a backing sheet whereby the two sheets are secured together by means of the adhesive to form the packing material. Another important feature of the invention comprises the provision of novel means for receiving the material as it leaves the finishing drums and successively stripping the same to'the desired width and cutting the same transversely into desired lengths.

Another object of the invention is to provide a machine which will perform all of the above stated objects and in addition will include novel mechanism for successively applying a coating of adhesive to a second sheet provided with embossed areas and pressing said coated sheet into contact with the backing sheet of previously formed material to thus form packing material having increased thickness with resulting increased resiliency.

Another object of the invention resides in providing a method of forming a sheet in which the longitudinal grooves are formed progressively; in which the grooves are set in the sheet by heating the same prior to forming embossed areas in the sheet by simultaneously heating the r sheet and forming transverse grooves therein; in which the embossed sheet is joined to a backing sheet and simultaneously heated again to set the adhesive, resulting in the finished packing material.

A further object resides in providing a pair of drums having groove forming members thereon for forming embossed areas in the sheet, and succeeding pairs of drums with only one drum of each pair having the groove forming members thereon, the cooperative drum of each pair being plain.

A further object of the invention is to pro-- vide. amachine having pairs of drums, certain of which have groove forming members thereon forsuccessively forming'nembossed areas in a sheet of paper and setting the embossed areas while simultaneously applying the embossed sheet to'abacking sheet.

With theseandivariousfothen objectsin view, the invention may r 'cbnsist of certain 'novel features of I construction and operation as will be more 'fully'. described 'rand particularly pointed out'in the specification, drawings and claims appended'hereto. I 1

Figure 5 is a sectional diagrammatic-view of and a Figure 11'is a fragmentary perspective view showing the'surface of the female forming drum.

The machine of the present invention is particularly useful in construction of packing material such as shown in detail in Figure 8, for packing fruit, radio tubes and other fragile articles, and also eggs for shipment, it being desirable in packing the latter to employ sectional dividers in connection with grooved sheets or fiats, each egg when packed being located in contact with a fiat or embossed area and being separated from adjacent eggs by the sectional dividers which have location in the grooves. The present invention contemplates a method and apparatus for continuously forming packing material of the kind described from rolled paper stock of a relatively inexpensive grade and further contemplates forming packing material of a modified form, more particularly illustrated in Figure 9, which consists in the flats or embossed areas extending from both sides of a backing sheet, the product having a substantial increasein resiliency and cushioning effect due to the additional embossed area.

ing a sheet 10 having longitudinal grooves l1 and transverse grooves 12 Illhe materialgof grooves il'and transverse grooves 12 asrat 16 and 17 respectively. In Figure 9 a slightly modified form of'material is :shownin which the sheet 10, in combination with the hacking sheet 15, has

secured thereto an embossed sheet 20, the embossed sheet 20 having contact with'thebacking sheet .15 at points 18 and corresponding respectively to the longitudinal and; transverse grooves of the embossed sheet .20. Packing material constrnntedas above has the advantage of increased resiliency-and resulting cushioning efiect'by reason of the additional embossed areas-on sheet Such material .finds'manyuses, especially is the same useful unpacking-eggs, .since it can be used as a dividing-partition, eggs having contact with the. raised areas of sheet -10 and other eggs in contact' with :the corresponding areas of sheet 20.

Referring more particularly to Figures 1 and 2, the machine is located upon any suitable base 21 having uprights 22, .23 and'24 secured thereto. Side frames 25 .and 26 are in turn supported from the uprights and held in spaced position by means of any suitable transversely extending tiewbars.

Located. upon the frames 25 and 26 centrally thereof are water tanks 27, thetanks supported a suitable distance above the frames and serving as a reservoir for supplying water to a number ofpipes 28. The tanks are provided for the purpose of cooling the bearingsand journal,

boxes of the various drums and rolls to be later described, since certain of these drums are electrically heated and in order to provide for efficient operation of the same, zitis necessary to provide a continuous flow of cooling water to maintain the trunnions at a moderate temperature.

At the feeding end of the machine, Figure 1, is located a plurality of stands 30 for supporting-a roll of forming paper 10 and a roll of backing paper 15. Each stand is provided with a suitable journal bearing 33, divided centrally thereof forming a member 31 pivoted at 32, the parts being held in operative position by means of winged nuts 34. The rolls of paper stock are supported on shafts 35, the shafts in turn having engagement in bearings 33 and. by reason of the construction of the bearings the shafts can be removed and :s'moilar shafts having a new roll of paper thereon can be substituted therefore. Upon the base-21 is supported an idler roller 3'? under which is passed the paper -.from rol-l 15, while secured to stand v22 is aplurality of idler rollers 38 underwhich passes the paper from roll 10 and from which it is run in-a substantially companion rolls 52, 5 3, 5.4:and55.

vertical direction between anumber of steam pipes 40 from small openings in which issues live steam, so that the same is directed against the surface of the paper. Located below the idler rollers 38 is a drip pan 41 which collects the moisture of condensate resulting from the a condensation of the steam due to its contact} with the paper. The paper sheet secured from roll 15 comprises the backing sheet of the material, while the paper from roll 10 comprises the embossed sheet and this latter, prior to forming the same with embossed portions, is passed through In Figure 8 the material is shown as compr'is--- a plu-rality of gathering rolls, which will be described.

' lIhe paper ldafter. passing between the steam pipes 40 tosuitably moisten the same, is directed over a heating roll 42 journaled at the extreme right handendof'the frames 25 and 26. As

shown in Figure 3, the roll is suitably heated by means of a length of resistance coil located within the roll, :thecurrent being conducted to the resistance-coil by means of connector rings 43. For receiving the paper from the roll 42 and for functioning as pressurerolls for squeezing the excess moisturewfromthe paper, are a plurality of cooperating rolls 44 and 45, the'upperroll '44 being-provided with aqgroove 46, while the-lower roll is provided. with a*bulge .-47-cooperating with the groove. Located in advanceof rolls44 and area plurality-0E forming-walls 48, 49, 50, 51, etc; which -have=-cooperative -relationship with The, rolls 48, 49,50 and 5 1 .are .driven--i-n a clockwise direction and-for thegjpurpose are providedwith suitable trunnions=to which are-secured gears. 56-.- The rolls-52;,53; 54 and 55=are driven in a counterclockwise direction by means ofgears 57 secured to thetrunnion-of the same, as shownin Figure 1. Shaf-tAB- is provided withshoulders 58 and 59, which cooperate with similar shoulders 60 providedonshaft 52. These shoulders are disposed-man offset relation as -shown in Figure l, so that as asheet passes between the rolls 48 and 52, agathering of the stock occurs at the center: thereof .in the, formation-in the sheet of offset portions which ,are subsequently finally formed into grooves.

The-precedingrolls 49 and 50 are also formed with-shoulders 62, while their companion rolls 53 and .54 are provided with similar shoulders which cooperate with 62' in the same manner as described in connectionwith roll48 and 52. Also provided on .rolls 49 and 56 are beads 63 and 64 which have engagement with grooves 65 formed in the companion rolls 53 and 54. These beads are arranged substantially in alignment with shoulders 58 and 59 of the preceding roll and finally form the ultimate inside grooves of the sheet in a manner to utilize the stock offset by the shoulders 52 and 53 as previously brought out. Upon the succeeding roll 51 are formed similar beads-66 andshoulders 65, the beads being aligned withbeads 63 and 64 so that they function to retain the shape of the grooves finally formed by the latter beads. The shoulders 65 function to form additional offsets in the plane of the paper, which are subsequently finally formed into grooves by means of the beads on succeeding rolls. The gathering of the sheet of paper therefore occurs with the forming therein of a groove by means'of the bulge 4'7 and groove 46, which initially gathers the stock without giving thereto my definite formation. By reason of the shoulders 58 and 59 offsets are formed in the stock which are subsequently finally formed into grooves; It is thus seen that, as the paper passes through the gathering rolls, the same is formed with grooves progressively beginning from the center of the sheet and continuing to either side thereof when it is subsequently submitted to further forming mechanism, to be presently described.

The rotation of the gathering rolls is accomplished by means of gears 56 provided on the upper rolls, which have meshing engagement with gears 57 provided on the lower rolls. Located between gears 57 are idler gears 68, which have meshing engagement with adjacent gears 57 so that all of the upper rolls, namely, 48, 49, and 51 are driven in a clockwise direction and at the same speed, while the lowersrolls 52 to 55 inclusive are driven in a counter-clockwise direction at the same speed. By means of meshing gears 68 and 69 secured to roller 44 and 45 respectively, the same are driven in the desired rotation and in accordance with the rotation of the forming rolls.-

The sheet upon leaving the forming rolls next.

'aside frames provided therefore. All four of the drums 70, 71, 72 and 73 are provided with a heating device comprising a resistance coil 75 which is located and rigidly supported within the drum. Connector rings 76 are provided for furnishing the resistance coil with a continuous supply of electric current, the rings being suitably secured to the trunnions 74 and having connection to the coil through openings 76. The drums 70 and 71 are provided with meshing gears 78, which by means of a suitable idler pinion, is driven in accordance with the rotation of the gathering rolls. Drums 72 and 73 are also provided with suitable driving gears 79 having meshing engagement to each other-and adapted to receive rotation from a main driving gear 80.

Drum 70 is'formed with a plurality of beads 81 which cooperate with'corresponding grooves 84 formed in the drum 71. It is to be noted that these beads and their corresponding groove allow the drums to receive the paper as it leaves the gathering rolls and permanently set the plurality of grooves previously formed therein. Referring to Figure 10 the surface of drum 72 is shown as provided with a number of annular beads 82, which are in substantial alignment with the annular beads 81 on roller 70. Intersecting beads 82 are a plurality of transversely extending beads 83, the annular and transverse beads forming indentations in the surface of the drum. The drum 73 has a formation for cooperating with drum 72 and is formed with annular grooves 85, Figure 11, which are intercepted by a plurality of transversely extending grooves 86, these grooves resulting in a series of raised portions upon the surface of the drum. As previously stated drums 72 and 73 are heated so that, as the paper is passed between the rolls the longitudinal grooves formed therein are still further set by means of the beads 82 and groove 85, while the paper in addition is formed with transversely extending grooves by means of beads 83 and grooves 86. By first constructing the longitudinal grooves and then the transverse grooves in a manner as disclosed, the paper at no time is under tension and the danger of fracturing or tearing is entirely eliminated.

By reference to Figure 1. it is seen that both the forming rolls and the gathering rolls are driven in accordance withtherotation of the main driving gear by means of the idler pinions described so that a sheet of paperinserted between drums 44 and 45 will be continuously fed to the gathering rolls and from the gathering rolls will be fed to the grooving and embossing drums with a uniform speed, so that no tearing of the paper nor undue strain is placed upon the same.

The next step in the operation of the machine is tov apply to the surface of the embossed sheet a coating of adhesive which'is accomplished by suitably journaling, in the ,side framesa plain surface roll 95, Figure 2, having cooperative engagement with a plain surface roll'96. The drums are suitably-mounted in the side frame; by means of trunnions 97 and are adapted to be driven by gears 98-having meshing .engagement witheach other,

- which in turn are driven-afrom ro1l;:73 by means of pinion 99. Locatedunder roll 96'and extending the entire width of the roll is a pan 100 for containing a supply of adhesive such as-sodium or potassium silicate,the pan being so located in relation to roll 96 that a portion of the roll will be immersed in the adhesive. Located adjacent the roll 96 is a scraper 101', which is spaced a slight distance from the periphery of the roll so that the surplus adhesive carried by the roll will be removed-and allowed tov drop back into the pan. The paper as it leaves the embossing roll 72 and 73 is fed between rolls 95 and 96, which results in coating the bottom surface of the sheet with an adhesive, the bottom surface however, comprises merely the grooves 11 and 12, since the; sheet is provided with the embossed areas and the grooves are the only part of the sheet designed to engage the backing sheet. The next operation is therefore to bring in contact with the embossed sheet a backing sheet, and this operation will be now described.

As shown in Figures 2 and 4 a second embossing roll is provided including drums 102 and 103,

each having a cooperating plain surface roll 104 and 105 respectively. Also associated with the embossing roll 102 and its plain surface roll 104 is a second plain surface roll 106, the latter rolls functioning to present to the-embossed sheet the backing sheet 15. The drums 102, 103, 104 and 105 are provided with suitable trunnions 107 and by means of adjustable journal boxes 108 are journaled within the side frames 25 and 26. These rolls are also heated in a manner as described in relation to rolls 72 and 73 by means of a length of resistance coil 109 located within the drum and supplied with current by means of collector rings 110, secured to the trunnions described. By means of gears 111 secured to the drums the same are driven in unison by reason of the idler pinion 112 having meshing engagement with gear 98 and pinion 113, which has meshing engagement with adjacent gears 111. The drum 106 respective members 132 at'l45.

is also :driven. bydhe --'desire'dtspeedf::as'gear .114 has meshing engagement with the corresponcv ing' gear 111 on'the'drum .104. By'referring'to Figure 5 it will .be;seen .that'thebacking paper15 is run over .rollersflintil the same is presented-to roller 106 which provides a smooth surface ."for taking out any creasesin the paper and for subsequently presenting-the same to drum-104 where thesame is brought into contact with theembossed paper .10 to'which' hast been-applied thecoating of adhesive as "described; By mean's of 1 the heat in the drums'1ll2;.1='03; 104-and 105' Ire- I spectively, the formation of the embossed areas 01 thelpaper is finally set,- and'ini addition "th'e 'ad-f hesive is dried so that its adhering-- qualities are materially.increased,"whereby,' when the material: leaves rolls 103 and 1105; the sheets willbe securely' united, thepacking- "material. having'a form r as shown in Figure '8. 'For'stripping the material into desired widths cutters 115 are 'employed and mountediupon transverse shafts 116and'117 suitably journaledtin the side 'frames.- Pinion 118" meshing with gear 111 serves: to drive'shaft 117 which turn drives-.shaftii 16' by means of-meshing pinions 120 secured' to the'sh'afts respectively.

The delivery =end-1 of the machine rat-themes ent invention' contemplates novel mechanism for cutting the packing material iiito desiied leng'ths without causing buokling ori damageito the p'receding portionv-ofi the hma'terial. The structure clearly shown in FigurQ-isdriveri "by ineansoffabelt 12-1 which transmitsf-power' from -the' pulley 92 to a speed-reducing:mechanism-designated in its entirety by 122. "-"Belt"-1'23 "connects the speed reducing mechanism 'to a?'tra'nsvnar-se shaft 124 tU- which is suitably secured 'ai cam 125 formed to provide a cam race .125, in which .op'eratesa; roller '7 127. Located upon base' 21 are verticalarms 128 pivoted at 129 r and having connection -to' a 'link 130 which inturn'ha's roller12 7 rotatably secured thereto.- The :left end' of frames 25 and 26-are formed with an upper'be'aring-surfaoe 131 upon which is mounted for-slidably movement thereon members 132. Members1-32 are'joined bytrans- 1 verse-shaft 133 which suitably spac'es'themembers' and which foi'ms a mounting for 'a'rms '134 to which are seoured'a' cutting blade-135. "Referring again toarms 128* it is 'seenthat th samea'ie" connected" at their upper end to links'136 which are pivotally connected at- "137: t'o"'tlie sli'dable' members 132, resulting in an actuation of the members '132 in accordance with movement of arm 128. This'armis in turn" actuated by'cam 125 and the movement is such that the members 132 are re'oiprocated upon the bearing surfaces 131 formedin the frames 125'and 126.

Bearings 140 formed integrally with members 132 provide a mounting foratransverse shaft 141 to which is "secured a cam 142. The cam is adapted to engage a pin 143 provided on arm 144, the arm being in turn pivoted to oheof the Suitable linksf 146 and 147 serve to operatively connect the arm 144 to the shaft 133 journaied upon the slidable members. Rotation of shaft 141 is accomplished I by providing the shaft with a suitable gear and connecting the same to shaft 124 by means of a belt 150.

As the finished material leaves the cutters 115 it'is' presented to retarding rolls 151 and 152 suitably journaled within the side'frames and-driven by means of gearing from the cutter shaft 117. For adjusting the spacing of theretarding rolls' a member 153 is provided mounted inthe side' frames and functioning to adjust the-vertical traveling in -syhchron'ism readers height of the upper retarding roll by means'of material. Depending from the members 132 and .positioned 'level with the -endless'tapes 156 is a block 157 provided in its upper surface with a second cutting blade 158 for cooperating with cuttapes functioning as a supporting means fdr' the" ting blade 135 to cut'the packing material transversely. The packing material in out form drops to a table 1 60 supportedby'means' of a leg 161-, the table providing abearingfor theshaft 162. Endless tapes 1 63 are mounted on shafts 162 "and 155, the lat'terbeing-driven by belt 159 from asuitable pulley located'on shaft 154. The 'table 160 therefore forms: a delivery mechanism for presenting to 'the operator individual sheets of the material 165' out to'the desired lengths.

The members 132 have reciprocating movement and in one direction, travel against the direction of traveI 'of the packing material,"=but in their" return movement the member's travel at a rate of speedsubstantially equal tothat' of the packing material. The pivotal movement of shaft 133 to -pause i the 1 cutting movements of 'blade" 135 is so tii'ned that-with the members132 traveling towardsthe -right,Figure 2; the blade 135'Wi11 be disengagedrflohi' blade-158; but"as"the= members 132 i begin their travel: towards "the left' blade 135 travels" downwardly a'sthehigh part of cam 142 engages pin 143'an'd the movementof blade 1'35 continues fuhti'l the travel towards the left of members "132 is substa-ntial1y completed. It is thus seen that-engagement of blade 135 with blade 138 wiIl out the materialtrahsversely without-causing buckling oflthe material, since the cutting is accomplished with the mechanism with" the travel of the packing material;

Referring 'to Figur 6 a modified 'formo'f mechanism fo'r 'mak'ing-packing material is disclosed, comprising a 'seriesof form'ing 'rolls 2'44; 248, 249, etc.', which "operate asdescribed and which present the sheet to-a'series of forming drums and embossing drums 2*10 ahd'272, respectively. In

advance of'the drums are a'plurality' of plain surface drums 295 and 296, which cooperate with a. and is fed over rollers to a'pluiaility of drums 300 and "501 the latter drum operating in "conjunction with-a pan 302 containing'sui'ta'ble adhesive such as sodium or potassium silicate for applying to the undersuriace of-theembossedsheet 20 a thin coating of adhesive. As previously explained, with the preferred modification a backing sheet 15 is-employedwhich is 'run over suitable rollers located in positionfor' presenting the sheet to suitable mechanism for bringing the same into contact with'the previously embossed sheet to unite the same together into the finished packing material. With-the apparatus as shown in Figure 6 the backing sheet 15 is run over roller 303 and presented to a plurality of cooperating embossing drums 202', 203, 204 and 205. These embossing drumsare of the same form'and character as drum 72 previously described, having annular beads provided {on 'theperiphery thereof with transverse'intersecting beads forming the surface of the drum into a plurality of depressed portions. These depressed portions cooperate with the embossed areas on the sheet 10 and the sheet 20 and press the same into contact with the backing sheet 15. As the embossed sheets have previously been coated on the proper surface with adhesive uniting of the three sheets takes place, thus forming the completed packing material, as particularly disclosed in Figure 9.

The usual form of mechanism for cutting and stripping the material is embodied in cutting rolls 220 which cooperate with retarding rolls 251 and 252 to present the material to' the transverse cutting mechanism including the cutting blade 235.

It is to be understood that I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
