Application filed January 29 1926. Serial No. 84,740. i

The present invention relates to collecting, folding, and dehvery apparatus of rotary web perfecting presses, and more particu larly to the construction andmode of opera.-

tion of the. collecting cylinder of a press of of the oncoming web, and the two are led forward together and adjacent to each other around the folding cylinder whena second section is cut from the web. The two sections are then folded together and delivered as the finished product.

If the trailing edge of the first section overlaps the cutting knife when the second section is cut, narrow strips of paper, which the pressmen call sauerkraut will be cut from. the first section. This is undesirable and objectionable. i i

' T 0 meet this particular problem the structure shown 7 of June 16, 1903, was devised, The collecting cylinder which in this patent is also shown as a cutting cylinder, had a part of its periphery cut back or clearance into which the trailing end of the first section could be thrownat the time that the knife was projected tocutthe second section from the web.

V The growth in modern newspaper work now requires. a press capable of collecting and folding a product varying in size from a few pages to sixty-four or more pages, and this demand has greatly complicated the problem of collecting. I y

While the clearance provided in theEvensen patent abovementioned for the trailing end of the section is essential to get a clean out free of sauerkraut, no: matter What the thickness of the web may be, an appreciable increase in'thethickness of the web requires a reduction in some manner in the diameter and the effectiye circumference of the cutting and collecting cylinder to secure proper folding remade ee te e e ae i f t was in Evensen Patent No. 730,892

to provide a recess. accompanying and prevent chokes inv the folding mechanism. If these alterations materially reduced as is the case, the same difficulties arise from having the diameter and effective circumference of the cutting and collecting cylinder too smalhall as here after explained. w i

To overcome thesefdifiiculties forj'webs of varying thickness, 1 reduce somewhat the diameter of the cutting and collecting cyl-' inder itself, and reduce the effective length of its circumference. The effective length of itscircumference I find can be reduced by increasing the recessed or relieved part of the" cylinder, provided in the Evensen pat ent above mentioned, to form 'a longerde-- piession. Then to compensate for difierent thicknesses .o'f'webs to be run through the I 1nachine,I provide adjustablemeans for filling out to varying degree the aforesaiddepression in order to change. the effective length of the circumferenoeof the cylinder;

This means maybe a plurality of fingers pivoted together to extend fiout of the body of the cylinder to ffillout the depression,

or it may be a plate likewise pivoted' ian'd capable of swingingoutto varying degree to fill out the depression, or anyjother suitable means of equivalent effect. 3

Now,.in order to acquaint thoseskilled 7 1n the art with the manner of constructing and using a device embodying my invention, I shall describe in connection with the drawingsja machineemploy ing my invention. Inthe drawings 1 Figures 1, 2 and 3 are showing the web held by the impaling pins diagrams, 131g "1 on the cutting and collecting cylinder and being led onto said cylinder;

'Fig. 2 shows the first section which is dis l 1 posed on the cutting and collecting cylinder i I being severed from the web and theadvance edges of both the web and the section being seized by theimpaling pins of the-folding cylinder;5 v V -Fig. '3shows the trailingedge of the first section thrown 'into the relief o'r depression on the cutting cylinder in advance of the eredfromthe web;-' Fig.1 in a side 'elevational] view of a cutft ing and. collecting cylinder embodying my knife just" before the second section is sev;

rod 23 extending through integral lugs 24 formed on the back sides of the fingers 19.

I A cover plate 25 is placed at each end "of the cap screws moving through slots 29 in the end plates '25 'to'permit of common adjustment of the plates or fingers 19 simultaneously. It can now be seen that by releasing the cap screws 28 the plates or .fingers 19 may be swung in common inwardly or" outwardly with respect to the slots 18, so as to bring a greater or less extent of said plates up to the main periphery of the cylinder 5. By this means the effective length of the circumference of the cylinder 5 may be varied without interfering with the portion of the recess or depression immediately in advance of the knife 7.

While I have shown the adjustment plates or fingers as being disposed in the forward part of the continuous depression 17 it is to be understood that a depression might be formed upon another part of the periphery of the cylinder 5, and its extent varied by like means without departing from my invention.

Also, instead of having a series of fingers or plates 19 extending through the slots 18, a continuous or overhanging plate, such as shown at 30 in Fig. 8, might be employed, either in connection with a part of the depression 17 or a separate depression, as may be desired. As shown in Figs. 8 and 9 a longitudinal recess 31 is formed in the bottom of the depression 17'adjacent its leading edge 32, and in this longitudinal recess a curved plate 30 is seated, this plate having at its ends pivot lugs 33 pivoted oncap screws 34 which are threaded through plates 35 secured upon the ends of the cylinder 5. The plates 35 are secured upon the ends of the cylinder 5 by the machine screws 36 which have counter sunk heads and the shanks of which are threaded into the main body of the cylinder. The opposite ends of the end plates 35 are secured by like machine screws 37 having counter sunk heads and shanks likewise threaded into the main body of the cylinder. The longitudinal adjusting plates 30 have slotted lugs 38 with adjustable cap screws 39 passing through the slots and threaded into the plates 35 to clamp the slotted lugs in any desired position. Thus, by loosening the cap screws 39 and swinging the adjustable plate 30 about the pivot '34,

the efiective circumferential length of the cylinder "may be changed moving the v plate 30in or out to a greater or less degree and then clamping the sameby means of the clamping'screws 39. 7

Attention-is called to the fact that whereas in theform shown in Figs. 4450 7, in-

clusive, the trailing edge of the adjusting means moves i d out in he m Shown m-Flgs. 8 and 9 the leading edge fth adjusting means30 is swun in and out Either method may be employedrega-rd being had to the space and material re quirements of the particularinstallation;

It may now be seen that my invention pro vides a cylinder which is adjustable incircumferential length without 4 interfering with the are of the depression-which receives the trailing edge of the first section or sheet, so that assuming that the proper length of circumference of the cylinder has been provided, the trailing edgeofthe first section or sheet will be permitted to be 7 thrown into the depression or recess to prevent the same bemg again out by the knlfe 7,

It will also be seen that by changing the j effective circumference of the cylinder provision is made for handling sheets or sec tions cut from webs of different thickness.

By my invention it is possible to make the cylinder considerably under size to take care of large products because I can bring out the circumference to any size, within limits, for proper operation with a smaller product. i

I do not intend to be limited to the details shown and described. j
