PAPEB-CRINKLING APPARATUS.
Application led July 16.
This invention relates to an a paratus for crinkling a web of paper or the e and has as its object to provide an apparatus of this sort having various features of novelty and advantage. More particularly an aim of the invention is to provide certain improvements in the paper crinkling machine illustrated in my Patent N o. 1,548,790 issued August 4, 1925. One' of said improvements consists in Yproviding pressure means forl insuring proper stripping of the web from either or both of the cylinders at the desired points. f
Other objects will be in art obvious "and in part pointed out`more 1h detail herein' after.
The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified inthe lconstruction Yhereinafter set forth and the sco e of the a plication of which will `be in cated in t e appended claims. 4 v In the accompanying'drawings wherein I have shown two embodiments which the present invention may take:
Figure 1 is a plan view showing' my improved arrangement, this view bemg taken substantially on line 1--1 of Fig.` 2;
Fig. 2 is a Vvertical sectional view taken substantially through the center of the apparatus and on the line 2--2 of Fig. 1;
Fig. 3 is an en1arged -detail view of adjacent portions of the'vacuum cylinders;
35 Fig. 4 is a view similar to Fi 1, this view being taken substantially on e 4-4 of Fig. 5; and i Fig. 5 "s a vertical sectional view taken substantially on line 5--5 of Fig. 4.
Referring to the embodiment illustrated in Figs. 1 to 3, A designates` a cylinder which is adapted to carry a web tota receiving lcylinder B. These cylinders are closely'adJacent and just out of contact. The
receiving cylinder B has a slower-peripheral s eed than has the delivery cylinder A, so that as the paper is delivered from once linder to the other it is crinkled. -In is embodiment the cylinders rotate in op site directions. 'The cylinder A is provide with a multiplicity of perforations 10 'and the cylinder B is likewise rovided with a plurality of perforations 1 .v The cylinders are geared together so as to rotate at the desired relativespeeds. thepresent instance the 1927. Serial No. 206,255.
The web of paper or pulp designated by the numeral 20 may come from a suitable supply roll or from al paper making machine', nelther of which are shown as they 'form no part of the present invention.' The web passes between the lcylinder 10 and a pres-v sure roller 21. This roller presses the paper against the cylinder 10. If it -is desiredto produce transversely crinkled paper which is ongitudinally corrugated, the pylinders may be circumferentially corrugated as illustrated in Figs. 1 to 3. The circumferential ribs 22 of the cylinder A match with the grooves 23 of the cylinder B. Also in this case thel roller 21 may be circumferentially corrugated and mesh with the corrugations of the cylinder A as illustrated. 'Ihe roller V 21 may be connected up to the cylinder A so through gears 25. Also the circumferential ribs of the cylinder B may be ofa wa formation, thus providing these ribs wit riilles 26 and clearances 27 between the riiiles. The cylinder B carries the cross crinkled and longitudinally corrugated paper to a receiving belt 28.
In accordance with the' present invention, there is provided, preferably -in each cylinder, a vacuum device for holding the paper against the peripheries of these cylinders, and' also pressure means for stripping the paper from the cylinders at .the desired points. Within the cylinder A is a hollow stationary core 30 upon which the cylinder A closely fits. This core is open 'for a portion of its length and particularly between the roller 21 and the point of transfer from the cylinder A to the cylinder B in order cthat` when suction is set up within the core, air may be drawn through the perforations 10 with the result that the atmospheric res Asure will holdthe web against the perip ery lo'fthe cylinderA up' to approximately/the transfer nder A to the cylinder Eoint from the c as a hollo'wv hub The core 30 l31 connected to a vacuum dpipe 32 in order that air'mmay be exhauste p rom the main chamber of the.V core. The core 30 is further providedjwith a. pressurel chamber 33 which 110 ety is open at its outer end, that is, at the inner periphery of the cylinder A. The mouth of this chamber is adjacent to and preferably is slightly to the delivery side of the point of transfer from the cylinder A to the cylinder B. The pressure chamber 33 is connected by a pipe 34 to a suitable pressure device, not shown.
The cylinder B is provided with a core 36 which is generally similar to the core 30. The suction hchamber of the core 36 is connected by a pipe 37 to a suction device, and the pressure chamber 38 is connected by a pipe 39 to a pressure device. The suction or vacuum chamber of the core 36 is cut away from substantially the point at which the paper lis delivered to the cylinder to the point at which it is discharged from the cylinder. The pressure chamber 38 has its mouth disposed adjacent the receiving belt 28. The core 36 blanks the cylinder through the remaining portion of its periphery. The operation of the apparatus shown in Figs. 1 to 3 is briefly as follows: The web of paper 2O is delivered from a suitable source of suppl and either in dry or moist condition, dependI ing upon the requirements, between the roller 2l and the cylinder A where it is caused to take the corrugated form of the cylinder A. Between the roller 2l and the cylinder B the web is caused to adhere to the periphery of the cylinder A by the suction created within the main chamber of the core30. When the web is transferred from one c linder to the other it is transversely crin ed, owing to the fact that the cylinder B rotates at a slower peripheral speed than the cylinder A. Also due to the riilies 26, the crinkling operation is expedited and the desired design 'may be given to the web. After the paper has come into contact with the cylinder B, it is stripped from the cylinder A in order to insure its roper transfer by the combined action of t e pressure within the pressure chamber 33 and the suction within the core 36. ihe transversely crinkled and lon itudinally corrugated paper is caused to a ere to the cylinder B between the cylinder A and the dehvery belt by the suction within the core 36, and when the aper comes opposite the belt 28 it is stripped) from the cylinder B by the pressure within the pressure chamber 38, this pressure of course being effective throu h the perforations 11.
Re erring now to the embodiment shown in Figs. 4 and 5, the cylinders A and B are generally similar to the cylinders A and B of the preceding embodiment, but they are not circumferentially corrugated, the cylinder A having a plain surface and the cylinder B having a riflled surface, the riles being desio'nated by the numeral 40. Also in this emodiment, the cylinder B' rotates in the same direction as the cylinder A and ,at a slower speed than the cylinder A. The web of paper 2O passes about suitable rollers 41 and onto the periphery of the cylinder A against which it may be pressed by a roller 42. The cylinder A is provided with a stationary core 43 the chamber of which is connected up by a pipe 44 to a suitable suction device. The core blanks that portion of the cylinder with which a web is not in engagement. The cylinder B isprovided with a core 45 which is similar to the core 36 of the preceding embodiment. The core 45 .has a pressure chamber 46 which is'connected u by a pipe 47 to a pressure device. 28 esignates a receiving belt.
In the embodiment shown in Figs. 4 and 5 the web is carried by the rotating cylinder A to the cylinder B. Owing to the fact that the cylinder A operates at a slower speed and has rifiles, the paper is transversely crinkled on this cylinder. The suction within the core 43, and effective through the perforations 10', causes the paper to adhere to the cylinder A and the suction withinthe core 45 causes the aper to adhere to the periphery of the cy inder B between the point where this cylinder receives the paper and the pressure chamber 46. The pressure within the chamber 46 is effective through the perforations 11 in the cylinder B' to strip the paper from this cylinder.
As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof,V it is intended that all matter contained in the above description or shown in the accompanyin drawing shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the language used in the following claims is intended to cover all of the generic and ecic features of the invention herein escribed and all statements of the sco e of the invention which, as a matter o guage, might be said to fall therebetween.
