Description
EEEEEEEEEEEEEEEEEE TS if i Y 53M :EN l i i Patented Aug. 13, 1935 Courtney P. Win-terrand DunbarA. Rosenthal, i Chambersburg, Pa.
"Application .lanuaryl19, 1935,'Serial`No. 2,572
v5, claims. (o1. 20s-57) Thislinvention relates to packages of `superposed paper sheets and more-especially to a novel package of crepe` paper Atowels or 'the like.
JAn `object of the `invention `is `to Aproduce a package `of superposed crepe paper towels-each sheethaving extreme softnessanda velvety tex# ture, and the sheets in `thepackage being-so condensed in` comparison with conventional packages of paper towels that the improved package will oecupyfless storage-space so `thatthelcost of shipping and storing the improved packages is correspondingly reduced.
l Heretofore, it has beenl customary 4to" `effect softness of papersheets by' means of embossing rollers, fin which casethe paper insingle'thickness is fed `vthrough the embossing "rollers in a continuous web. process does not reduce `the thickness `of the paper, `butin manycases increases the same.4 In accordance with the `present invention, the crepe paper towels areiirstorganizedintoa suitable v piled-stack, andthe entire stackis thensub-v jected 4to a numberof blows of` progressively increasing pressure until the maximum pressure is-reached During Vthe hammering, the stack. is
l held in such` manner as `to prevent distortion and the hammering or pressure results .in-crushing-of the sizing or iber binding material throughout the stack and "thereby not onlymakes the sheetsv softer but 'reduces the thickness of `the package. In an application 'for patent, Serial No; 727,572,
iiled May 25, `1934, a process and apparatus are disclosed for making the package onstack `of paper "towels forming 1the subject matter of the In 'that application 'it was about 1000 pounds upwardly, are suitable for the making of-the"improvedfipackage, but the softening Veffect is increased 4in proportion to the pressure. In practice, approximately 1500 pounds ram pressure has given very satisfactory )results on certain kinds of paper without excessive power requirements, but in actual practice,` it is best to use ram pressures of approximately 40,000 pounds up to 100,000 pounds for stacks of folded towels, napkins, etc., made of crepe paper.
The invention will be described in vconnection with the accompanying drawing 4and it consists in the novel features hereinafter described in detail, illustrated'invsaid drawing, and more paro ticularly pointed out in the appended claims.
In the drawing: Fig. 1 is a side elevation, partly in vertical longitudinal section, of one form of apparatus However, the embossing suitable topmaking the improved package of crepe paper towels.Y l
'-Fig', 2 is `a perspective-View of the improved package.' vl In accordance withv the present invention an ordinary or yconventional stack or package. `of crepe paper towels fis transformed in such manner -that the resultingpackage `isof materially reduced thicknessinlcomparison with that of a conventional "package and each towel is softer than the crepe "paper towels "heretofore known.
These results are brought about by crushing `the sizing, ber binding `material or other stiffening throughout the package. ,In order that 'the invention may be understood it is pointed out that l in one method of lmaking packages of crepe paper towels, the wood pulp employed as raw material is 'beaten whilein the 'presence of water so'asto `convertithe same into a `pasty mass. Thenresin soajp or any :other suitable sizing agent is .added to the 'mass and' the .beating is"continued until the disintegration of "the pulp is complete. At this timeralumzor-thelike'is added to the mass for the lpurposezof precipitating the resin or sizing on to theljlibers "of the mass. vNowthe mass is fedito a :crepe paper machine Where it is formed intoa web of `creped paper and is dried. This drying, of course, causes the sizing and any` other*V constituents within the mass which is capable of `stiiening under heat, to stillen the sheets, with Ithe .result that towels made' from such paper :are relatively stiff and more por less harsh :to the `skin ofthe user. After the web is creped and dried lit is run through a folding ma,- chine ywherein the web isfolcled and out into towel'lengths and nallyrrthe resulting sheets are placed in superposed `relation tomake up the stack `which `forms `the 4package-of crepe paper towelsn l Y, i Y
As disclosed in the above mentioned patent application, such stacks are treated in a particular way in order to form an improved crepe paper towel package. In order that such treatment may be readily understood from the present application, it will be noted that 4 designates suitable supports carrying horizontal shafts 5 on which are mounted pulleys or rollers 6 and 1. The pulley 6 is fixed to its shaft. A belt 8 is mounted on the pulleys and is adapted to feed stacks 9 of the paper articles through the compressing Pivotally connected links I3 and I4 connect lever I2 to a crank I5 on the main shaft I6 of the machine.
Supports Il at the medial portion of the machine carry an anvil I8 across which the upper bight of the belt travels in order to bring the stacks successively beneath the hammer I9. The latter is vertically guided by a guide 20 fixed to the supportsy i?, and the upper end of the hammer is pivotally connected at 2i to a link 22 suspended from a crank 23 fixed to the main shaft I6.
The upper face of the anvil has a fiat surface intermediate its ends, and the hammer Yhas a lower flat surface corresponding thereto, but a long horn or projecting shoe 24 extends forwardly from the hammer toward the roller 5 for a purpose hereinafter described.
The main shaft may be driven by any appropriate prime mover, for instance, through the instrumentality of a belt 31 which drives a pulley 38 fixed to the main shaft.
In operation, it will be understood that when the main shaft I6 is turned in a clock-wise direction, the hammer I9 will be reciprocated, and while the hammer is moving upwardly, the belt 28 will be moved in a clock-wise directiomand the beltV 8 in a counter-clock-wise direction. Of course, the belts will be stationary when the hammer is in its lowermost position. In accordance with such method, the stacks or packages 9 are placed on the belt 8 at the right end of the machine, and the belt is advanced between strokes of the hammer. In practice, the belt advances about five inches for each stroke of the hammer, and the projecting horn 24 acts to gradually reduce the thickness of the package or stack step by step with graduallyk increasing pressure until the package reaches the iiat part of the'hammer. Then the maximum pressure is brought to bear on the stack for the purpose of materially reducing its bulk. During such operation, the upper belt cooperates with the lower belt to prevent distortion of the package or stack and distribute the pressure uniformly over the entire area of the sheets.
As extremely high pressures are used in such method, a stack of paper towels or napkins of the customary thickness cannot only be reduced to about one-half such thickness, but the paper is given a velvety or soft texture so that a towel out of a package treated in thisv manner can be used on the face aswell as on the hands.
Prior to this invention, it has been customary in packaging crepe paper towels and the like, to compress the stack toi-a slight extent for the purpose of placing a retaining band of paper around the same, but this compression is of such minor degree as to in no way change the characteristics of the paper sheets.
It has been found that by using relatively high `pressures ranging between about 1000 and 100,000 pounds ram pressure, the customary stack can be reduced to about half the conventional size and that eachv towel or the like in the stack is so changed that its outer surfaces have maximum softness and a velvety texture.
While we have disclosed one form of apparatus and method which may be employed in the making of our improved package, we are aware that the package may be made in other ways without departing from the spirit of the invention as expressed in the claims.
What we claim and desire to secure by Letters Patent is:
l. A package of crepe paper towels in which the solidied resin or fiber binding material throughout the package is in crushed condition.
2. A package of crepe paper towels in which the solidified sizing throughout the package is in crushed condition.
y3. A package of crepe paper towels comprising superposed sheets of crepe paper, each sheet containing solidiied sizing in a crushed condition and thecorrugations of each sheet being relatively at in comparison with similar sheets in which the sizing is in uncrushed condition.
4. A package of crepe paper towels comprising superposed sheets of crepe paper forming a stack, each sheet containing solidied sizing material and such sizing material being in crushed condition throughout the package.
5. A package of crepe paper towels comprising a stack of superposed sheets of crepe paper, the number of sheets in the stack being equal to the number of sheets in a conventional paper towel package but the package being of substantially reduced thickness in comparison with a conventional package, and the solidified sizing in each sheet being in crushed condition.
