APPARATUS FOR PRODUCING CREPE PAPER.

Application filed March 14, 1925. Serial No. 15,515.

This invention relates to apparatus for producing crepe paper and involves it as a prod.- uct and also-the method of and apparatus for making the same. In commercial practice, it has been found desirable to make crepe elastic ina plural ity of directions. In other words, for practical purposes, I have discovered that it is of considerable advantage to provide for elasticity in the crepe, or the like, in a plurality of directions where such crepe is used for bags, containers, liners for cartons, and the like.

To that end, the present invention has for one of its primary objects the production of an apparatus for longitudinally pleating and crinkling a web of paper, fabric or other material either prior to or after said material has had 'cross-crinkles formed therein.

The apparatus includes instrumentalities for feeding and pleating the web, for effecting a crowding of the pleats as the web travels through the apparatus, and for finally pressing the pleats into crinkles as the web .passes from the apparatus. V The invention also involves a unique method of creping paper or the like, in the practice of which said apparatus may be employed.

The inventionfurther involves the product resulting from the practiceof my improved method. I

The apparatus contemplates action upon the web either while dry'or wet, and is capable of use in connection with either or both of the I principles disclosed in my pending applications Serial Nos. 704,867 and 704,868, filed April 7, 1924.

The method may be practiced with various types of apparatus, but I prefer to utilize that p which is herein disclosed, it being understood that even this apparatus is susceptible of a wide range of modification and variation Without sacrificing any of the salient features of my inventive-concept.

Other objects and features characterize the f apparatus, and they will in part be apparent a'nd'in part be made to appear in the description hereinafter setforth.

,In the drawing 1 for; g my'iiivention;

I Fig; 2 is an enlarged view in rear elevation, also fragmentary, showing the relation of the upper and lower pleating instrumen- Figu're 1 is a fragmentary view in top plan ainaclnne constructed in accordance with talities and the mechanism for driving the same, and means for varying such relation;

Fig. 3 is an enlarged fragmentary view in side elevation of the structure Fig. 4 is a fragmentary enlarged detail sectional view illustrating the relative positions occupied by the pleating and the crinkling instrumentalities; and

Fig. 5 is an enlarged detail view showing the manner of mounting of certain of the beltcarrying shives on the apparatus.

Referring to the practical embodiment of the invention illustrated in the accompanying drawing, the reference- characters 1 and 2 designate, respectively, upper and lower frame members or plates of a machine adapted to function for the production of a crepe product. The lower plate 2 is designed to be mounted, preferably, in a horizontal position, upon suitable standards (not shown), and the upper plate 1 is adjustably .supported in spaced relation thereto by resilient elements, such as springs 3, mounted on bolts 4 and disposed between laterally-extending lugs 5 and 6 on the respective plates.

The bolts 4;, which are preferably provided with winged heads 7 to permit easy manipulation thereof, traverse the lugs 5 on the upper plate 1 and are threaded to engage within threaded apertures 8 in the alining lugs 6 on the lower plate 2. It will be observed that the construction permits tightenirig'of the bolts in opposition to the pressure exerted by the springs 3 to move the plates nearer together and vice versa, and, in addition, to vary the pressure on the web A of the instrumentalities supported by the plates, and also to provide means for predetermining the depth of pleat produced in the web by said instrumentalities.v The arrangement of the bolts and springs in spaced pairs also makes it possible to yieldingly maintain plate 1 parallel with or at an angle to plate 2 and thereby vary the action of the pleatinginstrumentalities carried by these plates.

- The frame members 1 and 2 are similar, each comprising a substantially rectangular portion 9 and a triangular portion 10, the rectangular portion being cut out at its edge remote from the portion 9 to provide spaced. su porting arms 11. referably and as shown, means are provided for drawing or feeding the material through between the plates and pleating said material during its passage therebetwe'en;

- around one plate pass between such means including (in the present instance) a plurality of round endless belts 12 traveling around the upper and lower plates and so arranged that the belts traveling adjacent belts traveling about the other plate.

The belts 12 0f the upper plate 1 preferably pass over and are drivenby a series of uniformly spaced shives 13 fixed to. a common shaft 14 havin and revolves within the cut-out portion 21 at the apex of the latter. I This belt 19 passes about shive 18 and the central shive 22 on the shaft 14 and its path of travel is therefore along a central line of the apparatus throughout.

Similar cut-out portions 23 are provided at regular intervals in the front rearwardlysloping edges 24 of plate 1 to accommodate a series of shives 25, which are rotatably mounted on stub-shafts 25 fixed to the plate. It is to be noted, in this connection, that theshives 25 are spaced a, greater distance apart than are the shives 13 on the shaft 14, which construction causes the belts 12 to travel in an angular direction with respect to the line of travel ofthe belt 19 and to gradually converge toward the rear of the apparatus for a purpose presently to be explained. The cutout portions 23 are accordingly provided at the necessary angle to the central line of the.

machine to dispose the shives 25 in working relation with the respective shives 13.

Thelower plate 2 supports front and rear series of shives 26 and 27, respectively, about which travel belts 28 corresponding to the belts 12 and similarly traveling in a direction slightly angular to the plane of travel of the belt 19. The two sets of belts 12 and 28 are -so disposed relatively as to bear a working relation toward and a coaction between each other. That is to say, the plane of the lower portions of the belts 12 may coincide with the plane of the upper portions of the belts 28,

the two sets of belts thus running side by'side and preferably in the same direction and vat the same speed. By reason oft-he adjustability afforded between'plates 1 and 2 by the bolts 4, the horizontal relation of the two sets of belts 12 and 28 may be varied at the will of the operator; the pressure of the spring 3 between the plates permitting more or less of a yielding action of the belts on the web as it passes through the machine between the belts.

suitable bearing, as at 15, in the plate 1. ortions of the plate are cut As the web of material is started into the together w th the lateral pressure thereon due to the convergence of the belts acting to gradually form longitudinal pleats in the web and to gradually decrease the total width of the web as the material thereof is con-,.

sumed in the formation of the pleats. If desired, in some instances, it maybe desirable to omit the crinkling operation (about to be ing alone.

Preferably and as shown,- means are pro-' vided for applying pressure to the product produced by the apparatus and method thus far described to compress the pleats in the web into permanent crinkles, this means (in the present instance) comprising a pair of cooperating rolls 29 and 30 mounted on shafts 31'and 32, respectively, having suitable bearing, as at 33, in the spaced arms 11 of the respective plates 1 and 2. The shaft 32, as shown, extends at one end past the frame of the apparatus and has mounted thereon a pinion 34 for cooperation with a like pinion 35 fixed to the shaft 14, and a second pinion 36 for cooperation with a like pinion 37 fixed described) and merely accomplish the pleatthe upper portion of the apparatus, which has suitable bearing in the supporting arms 11 of said -member, and this shaft is driven through the agency of cooperating pinions 39 and 40 carried by shafts 38 and 14, respectively.

The rolls 29 and 30 being carried by the respective plates 1 and 2, the pressure with which they engage the web A passing therebetween is adjustable by bolts 4 and is of a yielding character due to the springs 3 disposed between said plates. It will be observed that the rolls 29 and 30 are so positioned that the meeting-line thereof is in the plane of travel of the web, with the result that the latter is fed therebetween directly after the pleating operation is completed.

From the foregoing, it is clear that the paper or like material, which may or may not a have been previously cross-crinkled, and may each support, the elements of one set traveling side-by-side and coacting with those of the other to pleat material carried by and between the elements, means for effectingmovement of said elements, and means for varying the relation of one set to the other.
