RICHTER, OF BERWYN, ILLINOIS, ASSIGNOQ' TO G088 PRHQ'TING PRESS COMPANY, A CORPORATION OF ILLINOIS WEB SUPPLYING AND CONTROLLING MECHANISM Original application filed March 22, 1928, Serial No. 263,624. Divided and this application filed July 26,

. 1980. Serial No. 470,820.

The invention relates to novel and useful improvements in web pasting means for webs drawn from rotatable rolls, and in certain aspects thereof the invention relates more particularly to such means as applied to fast rotary printing press, although in other of its features the invention has other applications.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

This application is a division of my prior application Ser. No. 263,624, filed March 22, 1928. 4

The accompanying drawings, referred to herein and constituting a part hereof, illustra-te one embodiment of the invention and together with the description, serve to explain the principles of the invention.

Of the drawings Fig. 1 is a side elevation of a mechanism embodying the invention;

Fig. 2 is an enlarged, fragmentary, end lelevation, taken substantially on line 2-2 of Fig. 3 is apo'sitional diagram showing the operation of pasting the webs; and

Figs. 4 and 5 are fragmentary elevations showing different stages in the pasting of the webs.

Referring now in detail to the embodiment of the invention illustrated b way of example in the accompanying rawings, the invention is shown a plied to a type of websupplying means or printing presses, wherein two web supply rolls are contiguously mounted on the machine frame, an exhausted roll being removed and replaced by a fresh full roll while the web from the other roll is running to the printing machine. The

resent invention provides novel means for bringing a fresh web supply roll approximately up to speedand attachin the two webs together to lead the fresh we through the printing press or other machine.

Referring now in detail to the present preferred embodiment of the invention, a frame 1 has at either side upright frame members 2 and 2, and each of these has oppositelyprojecting brackets 3 and 4, which are adapted, respectively, to support the shafts of web supply rolls a and b in operative relation to the tension controlling means and the web pasting mechanism. Two brake mechanisms are provided, one cooperating with Web supply roll a and the other cooperating with web supply roll I), both brake mechanisms being governed by a common control to the web-tension governed controlling means. The brake mechanisms are preferably constructed and arranged so that an exhausted roll may be removed and a new web supply roll may be inserted without displacing the brake mechanisms from their mounting on the machine, or disconnecting them from the common control. A single description is sufficient for both mechanisms. The roll mountin and brake mechanisms may comprise a sha or mandrel 10 passing through the web supply roll in the usual manner, the mandrel being journaled in the side brackets 3, 3 or 4, 4 of the frames. A new web supply roll is rolled in from the exterior end of the brackets along the tops thereof to the bearings for its shaft 10. A brake pulley 15 is fixed in position on one end of shaft 10 which projects outside of the corresponding bearing in frame bracket 3, the brake pulley being provided with a peripheral V-shaped groove. Working in the groove in the pulley are two arcuate V- shaped brake shoes 16 and 17, which are pivoted-to the ends of opposed pairs of brake arms 20 and 21. The web tension controlling mechanism for the web rolls may be of any desired or convenient type but is preferably of the type shown and claimed in the parent application Ser. No. 263,624, and is so shown in the accompanying drawings. Inasmuch as this part of the mechanism forms no part of the present invention, a detailed description of this mechanism is not included.

supply roll to make what is known as a runpester.

the embodied form of mounting and.

moving means for said web pasting rollers, there is journaled in the side frames 2 and 2 of the machine a shaft 171, and fixed thereon are two arms 172' and 173. Pivotally supported in the top of the arm 172 is a bar 174, and pivotally supported in the top of the am 173 is a bar 175. A roller 179 has its shaft journaied in the corresponding ends of the bars 174 and 175. To hold the roller 179 in longitudinal position and the bars 174 and 175 in alinement and position, the ends of the roller axle are. shouldered within the bars (Fig. 2). The shaft 182 of the roller 179 at either end of the roller and within the respectirehars 174 and 175 is adapted to pass into and out of the slot guideways 163 formed in the plates 161 and 162 fixed on the machine frame. In the opposite ends of the bars 17 4: and 175 is journaled a roller 185 which togather with roller 17 9, ma be provided with a resilient covering, as 0 rubber, the roller shaft 187 being held in place against longitudinal displacement, and the corresponding ends of the bars 174 and 175 being held in alinement and position by similar means to those already described in connection with roller 179, The shaft 187, at either end of the rolier 185 and within plates 161 and 162 is adapted to enter into and travel along the slot guideways 164 in the plates, similarly to the mechanism and operation at the other side of the press. Means are provided for man Bally rocking shaft 171 to effect the pasting operation at either side. Said means as embodied comprises a lever 191, fixed to one end of shaft 171 on the outside of the side frame A .boss 192 on the lever 00- operates with a boss 193 on the frame when the mechanism is in central or inactive position, as shown in Figs. 1 and 2, and a pin 194 passes into internal apertures in the two bosses and holds the lever 191 locked. in inacthe position. The entire mechanism is rocked either to the right or left about shaft 171, and one of the . rollers 179 or 185 is guided by the corresponding pair of slots 163 or 164, moving to and fro in the slots during the rocking of the entire device about shaft 179 to simultaneously swing the rollers 17 4 and 17 5 about their pivotal mounting on arms 17 2 and 173 to move the other roller to and from pasting position. This action will be apparent from Figs. 1, 3, 4 and 5. In the diagram of Fig. 3 it is assumed that the web I), approaching exhaustion, is to be pasted to a fresh web roll a. Handle 191 is turned to the left, and the successive'positions of the various parts of the mechanism are indicated by exponents a, b and 0 applied to the reference numerals for those parts. In practice, the lead end of the web of roll a has a band of paste applied thereacross and it is located just beyond the point where roll 17 9 will con tact therewith. When roll 179 is impressed in position 1790, it presses the running web b firmly against roll a which is thereby started into rotation, or roll a may be otherwise started to rotate. It has practically an entire revolution in which it is brought up to speed by the pressure of running web I) under roller 1790. As the band of paste on rotating roll a engages with running web 6, they are pasted together, web b is severed, and the lead of web a is carried through the printing press or other machine.

The invention in its broader aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the invention and without sacrificing its chief advantages. I

What I claim is 1. A web attaching mechanism including in combination means for rotatively supporting a. plurality of web rolls, a roller journaled at either side of arunning web, a. movable support for'both said rollers, a movable support for said movable support and additional means for guiding one of said rollers out of contact with the fresh web roll. 2. A web attaching" mechanism including in combination means for rotatively supporting a pluralit of web rolls, a roller journaled at either sidb of a running web, a movable support for both said rollers, a movable support for said movable support, and additional means for guiding one of said rollers out of contact with the fresh web roll while the other roller is pressing a running web against a fresh web roll.
