METHOD OF AND MEANS FOR SEVERING AND FEEDING A-WEB OF FLEXIBLE MATERIAL Filed March 28, 1955 3 Sheets-Sheet 2 INVENTOR 1 1054 1 Fewer BY M ATTORNEY J. PEYSER Jufiy 28, 1936.

METHOD OF AND MEANS FOR SEVERING AND FEEDING A WEB OF FLEXIBLE MATERIAL 3 Shets-Sheet 3 Filed March 28, 1955 g INVENTOR 15 0M fiwa ATTORN EY Patented July as, 1936 GE F E METHOD or AND MEANS FOR SEVERWG AND FEEDING A WEB OF mamas MA- TEREAL invention relates to a method of and means for severing and feeding a web of flexible material, and has for its main object and feature the accurate and speedy production of covers for a match-books from a web and the feeding of such covers to the conveyer of a match-book machine of the type shown for instance in my application Ser. No. 11,269 filed March 15, 1935.

In the accompanying drawings the invention is shown in a concrete and preferred form in which:

Fig. 1 is a top plan view of a device embodying the invention;

Fig. 2 is a view partly in side elevation and partly in section of the device shown in Fig. 1;

Fig. 3 is a perspective fragmentary view of the feed-table, deflecting member and knife;

Fig. 4 is a transverse vertical sectional view substantially on the plane of line H of Fig. 2; and

Fig. 5 is a more or less diagrammatic perspective view of the feeding and severing elements of the device.

I0 indicates a feed-table, the outer end of which is provided with a cutting edge H, and

I2 is a recess in the side of the table, the purpose of which will appear later. Below said'feedtable and forwardly thereof isa support l3 to receive a sheet or section from table l6. l4 indi- 3 cates a knife to cooperate with edge l l to sever a section from a web fed along table l0, and

I5 is a deflecting member to deflect a portion of the web into recess l2. Knife l6 and deflecting member I5 are mounted on a slide l6 recip- 35 'rocating in guides 11, and slide I6 is actuated from rockshaft ill by means of connections I9.

26 indicates a cover conveyer, the upper run of which is on a level with support l3. Said conveyer is here advanced intermittently step by 40 step by suitable means (not shown), and it will be noted that support I3 is cut away at 2! to permit feed dogs 22 to pass up through said support to engagethe back edge of the sheet and carry it along. 23 are reciprocating meml5 bers sliding in the framework, and provided with projections 24 to feed a sheet from support l3 'onto conveyer 20. 25 indicates a rockshaft actuating the members 23 by means of connection 26, and actuating the rockshaft l8 by means of 0 connections 21. Rockshaft 25 is actuated from eccentric 28 by means of connections 29, and eccentric 28 is mounted on shaft 30 carrying gear 3| receiving its motion from gear 32 on shaft 33. 34 indicates a pair of feed rollers here driven 5 continuously to feed web W forward from a web roll (not shown) to provide a slack and pendent portion W in the web. 35 and 36 indicate a pair of intermittently acting feed rollers to alternately feed and release the web, and it will be noted that one of said rollers, here 36, is mutilated or has high and low spots as shown, the web being fed forward when high spot of 36 engages 35, and being released when the low spot of 36 comes opposite 35. Any suitable means are employed to continuously drive rollers 34, 35 and 10 36, such, for instance, as sprocket chain 31 passing over sprockets 38, 33, 40 and M.

Web W is severed partially at W before it is fed through rollers 35 and 36, and this may obviously be done while the web is in transit from 35 its roll, or it may be done by a separate operation and the web rewound into roll form. This partial severance W is transversely of the web at one of its side edges and is at predetermined points in the length of the web, partial severg0 ance or slit W defining the size of the cover or sheet to be completely severed from the web. 5 Said web is threaded through rollers 3d, 36and 36 with a slack portion at W as indicated in Fig. 2, and the forward end of the web placed 5 on feed-table l0. Rollers M-maintain slack and pendent portion W in the web, and rollers 35 and 36 draw intermittently from said slack portion and advance the web along feed-table it. The high and low-spots onlroller 36 are of such so length and the speed of rotation of rollers 35 and 36 are so calculated and. timed that with each intermittent feeding movement of said rollers an amount of web in excess of the length defined by the distance between slits W is ad- 35 vanced. In so advancing the web, the partially severed portion of the web passes over recess i2 and, when the rear end of the forward web section is above said recess, deflecting member i5, the face of which is in line with that of knife id, 40 descends deflecting said partially severed portion into recess l2 thereby blocking the web when the undeflected portion of the next succeeding web section encounters the face of the deflecting member. Rollers 35- and 36, however, continue momentarily to feed the remainder of the web whereby a buckle W is formed in said remainder of the web. At substantially the same time that the undeflected portion of the next succeeding web section encounters the face of the demember, the partial line of severance reaches the plane of the cutting edge of knife I 4 and the latter almost immediately completely severs the web in line with the partial severance, and this action also tends to blockthe web and to create the buckle aforesaid as rollers 35 and 36 still continue to urge the remainder of the web forward. Rollers 35 and 36 now release the web and the weight of slack W retracts the web a certain distance and buckle W disappears. The object of the slight overfeed caused by rollers 35 and 36 is to render certain that sufficient web is always fed so that a cover of proper size will be severed from the web, defleeting member l5 and knife l4 preventing too large a cover from being severed from the web. In order to prevent buckle W from being formed too closely adjacent to the cutting devices, cover plates 42 may be arranged above table ill in closely spaced relation thereto and, if desired, spring-pressed plungers 43 or light springs may be carried by slide Hi to bear upon the paper and prevent slack W from retracting the web too far. The deflected portion W regains its shape and is not permanently deformed out of the plane of the web or sheet, and to assist the severed sheet W in passing to support l3, ejectors 44 carried by slide l6 may be used. Members 23 now advance and sheet W is transferred to conveyer 20 of the match-book machine.

I claim:

1. The method of severing a web of flexible material into predetermined lengths which consists in: partially severing the web transversely at a predetermined point in its length; advancing said web an amount in excess of that defined by its partial severance; deflecting the partially severed portion of the advancing web and completely severing it in line with its partial severance thereby causing a buckle to be formed in the remaining and advancing portion of the web; and retracting the buckled portion of the web.

2. The method of severing a web of flexible material into predetermined lengths which consists in: partially severing the web transversely at predetermined points in its length; intermittently advancing said web an amount in excess of that defined by its partial severance; deflecting the partially severed portion of the front section of the advancing web and completely severing it in line with its partial severance thereby causing a buckle to be formed in the remaining and advancing port-ions of the web; and, intermittently and alternately with the advance and complete severance of the web, retracting the buckled portion of the remainder of the web.

3. The method of severing a web of flexible material into predetermined lengths which consists in: partially severing the web transversely at a predetermined point in its length; maintaining a slack and pendent source of supply of said partially severed web; advancing said web from said slack supply an amount in excess of that defined by its partial severance; deflecting the partially severed portion of the advancing web and completely severing it in line with its partial severance thereby causing a buckle to be formed in the remaining and advancing portion of the web and stopping the advance of said remaining web portion thereby allowing the weight of said slack and pendent source of supply to partially retract the buckled portion of the web.

4. The method of severing a web of flexible material into predetermined lengths which consists in: partially severing the web transversely at predetermined points in its length; maintaining a slack and pendent source of supply of said partially severed web; intermittently advancing said web from said slack supply an amount in excess of that defined by its partial severance; deflecting the partially severed portion of the front section of the advancing web and com- 1 pletely severing it in line with its partial severance thereby causing a buckle to be formed in the remaining and advancing portion of the web; and, intermittently and alternately with the advance and complete severance of the web, ai- 1 lowing the weight of said slack and pendent source of supply to partially retract the buckled portion of the web.

5. A web severing and feeding device including: a feed-table having a cutting edge at its out- 20 er end and a recess at its side; means to feed a web partially severed at predetermined points, along said table, the partially severed portion of the web passing over the recess aforesaid; a deflecting member to deflect the partially severed portion into the recess aforesaid while the web is moving; and a movable knife to complete the severance of said web in line with its partial severance.

6. A web severing and feeding device including: a feed-table having a cutting edge at its outer end and a recess at its side; intermittently acting means to alternately overfeed and release a web, partially severed at predetermined points, along said table, the partially severed portion of the web passing over the recess aforesaid; means to maintain a slack and pendent supply of said web for the use of the intermittently acting means; a deflecting member to deflect the partially severed portion into the recess aforesaid while the web is moving; and a movable knife to complete 'the severance of said web in line with its partial severance.

'7. The method of severing a web of flexible material into predetermined lengths which consists in: partially severing the web transversely at one of its side edges at predetermined points in its length; advancing said web an amount in excess of that defined by the distance between successive lines of partial severance; de-

fleeting the partially severed portion of the advancing web before completely severing it and completely severing said advancing web in line with its partial severance, thereby causing a buckle to be formed in the remaining and still advancing portion of the web; ,and retracting the buckled portion of the web. 8. A web severing and feeding device including: a feed-table having a cutting edge at its outer end and a recess at its side; means to feed a web partially severed at predetermined points, along said table, the partially severed portion of the web passing over the recess aforesaid; a movable knife to complete the severance of said web in line with its partial severance; and a deflecting member to deflect the partially severed portion of the web into the recess aforesaid-while said web is moving and before the line of partial severance reaches the knife. 7
