Description
Dec. 17, 1929. 1', PETQ WEB JOINING. APPARATUS Filed March 1925 Patented Dec. 17, 1929 PATENT OFFICE JAMES T. PETO, 0F RIDGEWOOD, NEW JERSEY WEB-JOINING APPARATUS Application filed March 6, 1925. Serial No. 13,513.
This invention relates to printing presses, and it has reference particularly to the joining of the leading end of a fresh web to the web about to be exhausted so as to effect entry .of the fresh web into the press in that way and thus avoid stopping the press.
According to one feature of the invention, given means'to hold a part of one web in pendent position and coactive means, having an upwardly open intake enterable from above by the Webs, to press them together so as to cause them to adhere and be joined when an adhesive has been applied to one, there is meansto guide the other web in a substantially horizontal plane toward the pendent part of the first web and close to the nip of said pressing means. Thisarrangement affords the necessary clearance (over the said guiding means) for the hand manipulation of the leading end of the fresh web into the pressing means, which is best accomplished when the hand can be entered between the webs to smooth and regulate them, it being noted that each is frequently of more or less flimsy material (as newspaper) and that one is further wetted with the adhesive. In apparatus of this class heretofore devised, the webs were either both entered'laterally into the pressin means or both upwardly, which require special means to insure support of the lead ing end of the fresh web while waiting to be entered, or they were both pendent from means well above the pressing means so that it was difiicult to use the hand to enter the fresh web into the pressing means in a way to have it register squarely with the other web and not become creased in the incidental manipulation, thus to form a good splice or joint.
The pressing means preferably employed by me comprises two members (as rolls) one of which is movable toward and from the other. Another feature of my invention consists in a novel means for supporting these members and for controlling the position of' the movable member.
In the drawings,
Fig. 1 is a side elevation;
Fig. 2 a sectional view on line 2-2, Fig. 1; and
Figs. 3 and 4 are detail views of the Web pressing means, Fig. 3 showing the pressing means in active condition and Fig. 4 showing the same in inactive position, and in each of these figures theworking or old web is shown by broken lines and the new web by solid lines. I
A supporting means or frame structure is afforded by two uprights a which rest on a base 6 or the floor and have forward extensions a at the top to connect them-with the frame of the press (not shown). The supporting means or frame structure may also include two angle brackets c adjustably secured as by set-screws c on studs (Z which are fixed to the uprights of the frame structure by nuts d; the brackets may be adjusted toward and from each other on the shaft or around it, their normal position being such that one arm of each projects toward the press and the other downward.
The supporting means or frame structure also includes means for directing or guiding the two webs, as well as means for supporting the two. web rolls, the latter means in the present case being two pairs ofbrackets e and 6 (arranged one above the other at the back of the frame structure) in which the shafts f and f for the web rolls 9' and g are j ournaled. The means for directing or guiding the two web are as follows: Each web in the first place-extends up and over a roller h (h) journaled in suitably cushioned bearings i (i) of a well known type adapted to tension the web. The upper web A then extends forward over a roller from which it hangs pendent as shown in Fig. 1. The lower web B then extends forward over a platform is adjustable around the axis of and supported by a fixed horizontal shaft Z- of the frame structure.
The coacting pressing means are as follows:
The depending arms of the bracket 0 (which brackets are fixed as already indicated) afford journals for the shaft or gudgeons m of a pressure roller m forming one of said means. The other of said means includes, with a shaft n revoluble in the rearwardly projecting arms of the brackets c, a pair of pendent links 0 fixed adjustably to 'so arranged that the roller the shaft by set-screws p and a pressure roller 1 whose shaft or gudgeons 1' are journaled in the links 0. The coacting pressing means are of the one is laterally opposed to the rol er m included in the other means; also so that the platform is will deliver the web B over the roller m. It will be preferable to provide anti-friction rollers .21 on the shaft or gudgeons 1' of the roller At e ther side of the frame structure, but preferably at each side, there is ivoted on the stud t a lever u. This lever as a camslot 1/ which receives the anti-friction roller .9 and is arranged at an incline as shown in Fig. 1. Thus when either lever u is moved on the stud t as a pivot up or down it will shift the pivotally pendent pressing means toward or from the other pressure means.
Preferably a roller 4) is journaled on the shaft 'n in such position that when the web A is the fresh or new web and is waiting to be joined to the other or old web B its free or pendent end will be held more or less definitely over the crotch or entry between the two rollers m and q.
Below the pressing means is a roller w under which the web passes on its way to the ress. p 0pemtion.-The normal position of the movable pressing means is retracted, Fig. 4. Assume the working or old web to be the u per web A. The free end of the new web is then laid on platform 10 and pasted, ready for joining, as indicated at a; in Fig. 2
and introduced into the space between the two pressing rollers with its edge exactly between the most approximate or nipping portions of said rollers. \Vhen the working web is about to be exhausted one of the levers u is lifted and so brings roller gFinto coactin pressing relation to roller m ig. 3), whic is then rotated, with roller g, by the moving webAand so the other webis caused to be started advancing and the splice is at the same time formed due to the pressure; upon the s licebeing formedthe web A may be severed. hen web B is the working web and web A the fresh web the operation of joining is obviously substantially the same. In both cases the mechanism necessary is reatly simplified because the entering to t e pressing means being from above (the space between the rollers forming an intake 0 ening upwardly) t e free end of the fres web naturally 1611(5 itself thereto, and in both cases the operation is simplified and an accurate, effective and neat, joint is possible because one web is positioned to permit manual manipulation of the Webs in effecting the joining and a clear view of the joining operation. Due to the weight of the movable pressing means and the weight also of lever u, taken with the inclination of the slot u, the roller q is normally held clear (Fig. 4) of roller m and also in more or less fixed position notwithstanding the fast-moving and vibrat ing web may at times move in contact therewith. 1
Having thus fully described my invention what I claim and desire to secure by Letters Patent is:
1. In a web joining apparatus, the combination of supporting means, a pair of web pressing means therein, one being arranged laterally of and movable toward and from the other, and means to move the movable pressing means toward and from the other pressing means, said last-named means and movable pressin means having the one a cam-slot engage by the other and confining each of them against movement independently of the other.
2. In a web joining apparatus, the combination of supporting means, a pair of web pressing means therein, one being arranged laterally of and pivotally pendent in the supporting means and movable toward and from the other, and means, pivoted independently of the first named pressing means, to move the movable pressing means toward and from the other pressing means.
3. In a web joining apparatus, the combination of supporting means, a pair of web pressing means therein, one being arranged laterally of the other and including a link structure pivotally pendent in the first struc ture and a roller revoluble in the link structure, and means, supported inde ndently of the link structure, to shift the first pressing means toward and from the other pressing means.
4. In a web joining apparatus, the combination of supporting means, a pair of web pressing means therein, one being arranged laterally of the other and including a link structure pivotally pendent in the first structure and a roller revoluble in the link structure, and means to shift the first pressing means toward and from the other pressing means, the third-named means and said first pressing means having the one a camslot engaged by the other and confining each of them against movement independently of the the other.
5. In a web joining apparatus, the combination of supporting means, a pair of web pressing means supported therein, one bein arranged laterally of and movable towar and from the other, and a cam device, supported in the supporting means independently of the movable pressing means and mov able against the same, for moving said movable pressing means in one direction.
In testimony whereof I afiix my signature.
