. FABRIC HANDLING.

Application filed April 22, 1925.- Serial No. 25,166. H i

' In handling of rubberizedfabric it is customary where, sheets of such fabric are superposed, to insert a sheet of canvas duck or other suitable material, termed a liner, between the. adjacent surfaces of the'rubberized fabricto prevent adhesion. Where the rubberizedfabric is in the form of a web'it isfwound into aroll of liner material for thesame purpose. My-invention relates to a device for windingia web of liner material into aroll, and has for itsobject to provide a deyice of this character which may be conveniently usedin connection with a calender, cutter or other mechanism, and by means of which rubberized fabric strips or a web of rubberized'fabric may be wound into theliner in a more efficient and economicalmanner than has hitherto been possible and in a more compact form, resulting in maximum protection to the fabric and the utilization of the maximum capacity of the liner.

In the accompanying drawings which illustrate one embodiment of my invention,

Figure 1 is a plan view, 1

Figure 2 is'an end elevation,

Figure 3 is a detail of means for accurately positioning my device, and

Figures 4, 5 and 6 are detail views partly in section of the bearings supporting the liner rolls. I Referring to the drawings 1 designates the frame of the device which is supported upon flanged wheels 2 adapted to run'upon suitable rails placed in front of the machine in conjunction with which my device is used. In order to enable easy adjustment of the position of the device on the rails I prefer to provide one ofthefianged rollers with a lever 3 mounted on the shaft of the flanged by a spring .6 to engage suitable recesses 8 in one of the flanges of the roll; As will be evident a slight transverse movement along the rails may be imparted by rocking the lever 3 when pin 4 is in engagement with a suitably positioned recess 8.

Atthe rear of frame 1 I provide bearings generally indicated at'lO and 11, in which the shaft of the liner supply drum 5 is removably and rotatably mounted. As shown in Figure 4 bearing 10 is provided with a suitable bearing surface 12 in which is mounted a shaft 13 having an enlarged head 14 slotted at 15 to receive the squared end of the shaft of the liner supply roll. i

collar lfiisfitted on head 14 and is pro? vided' with a block or key 17 sliding in a groove 18. forming an extension'of groove 15. Theblock 17 in the position shown in Figure 4 closes-groove 15 to lock the liner shaft in position but releases the latter when n the collar. 16 is moved to the left in said figure. The collar 16 isadapted tov be releasably held in looking position by a spring pressed ball 19 secured in head l4and engaged-in a recess 21 in .the collar 16. The opposite end of shaft 13 is provided with a reduced portion 22 and a threaded portion 23 upon which latteris mounted ahand wheel 24 provided with a shoulder 25 engaginga disc 26 splined on reduced portion 22.

A second disc 27 isbolted to bearing 10 and a disc 28 of leather or other suitable material is interposed between members 26 and 27. As will be evident the tightening of hand wheel 24 will drawhead 14 against bearing 10 to increase the friction between rotating disc 26 and stationary disc 27, thus creating a drag on the liner as it is unwound from the'liner supply drum.' Bearing 11 is similar to bearing 10 just described except that the brake mechanismmay be' omitted. It will also be understood that any suitable means may be used to produce and control drag on the liner web ,andI do not confine myself to the specific means just described, for that purpose.

From the drum 5 the liner, indicated. at

80, passes under a guide rod 32, rotatably mounted in bearings 33"secured to frame'l at 33, over spreading rolls 34 angularly mounted to rotate in bearings 35, and thence around a drum 36 secured to shaft 38 freely rotatable in bearings 40 secured to the frame 1 at 41. The drum 36 is preferably of substantial diameter to minimize the tendency to throw wrinkles into the liner web as it is turned around thedrum.

A liner receiving drum 42 is rotatably and removably mounted in bearings 44 and 4'5 secured to uprights 46 forming part of frame; 1. Bearing 44, shown in detail'in- Figure 5 is similar to bearing 10 previously described except that the brake or drag mechanism of the latter has been replaced by a sprocket Wheel 48 securedby bolts 49 to a hub 50 splined on the reduced portion 22 of the stub shaft 13. Sprocket 48 and consequently drum 42 is driven by a sprocket sup iortenl in frame 1 The speed of motor 7 56 is controlled by anyconyentional means; Dru111 42 is thus positively drlven 1n the direction of the arrow in Figure 2 anddraws the liner material from drum 5 beneath rod 32, over spreadlng rolls34, and around drum 36. Through manipulation of hand wheel 24 suitable tension is applied to the liner so that in its passage from full 36'toidrum 42 it fol-111s a substantially smooth' taut'table? as at (30, npon whieh strips 01" sheets ofrub ber inedfabric maybe laid or otherwise received and Wblll'lkllllti) the-linen Preferably the movement of the liner isicontinuousbfut obviously it may be intermittently operated if desiredJ If desired afweb of rubberized fabric may be directly wouncl'into the liner as shown, forexamplefin the drawings ac companying my co-pending application Serial Nnmber'l,864=, filed Januarygfi; 1925. In addition to the advantages derived from presenting the linerin the form of table 60, by the useof my device the liner as it is rolled up maintained under substantially uniform tension and as a'result the liner and v rubberized labric'are lwound into a compactrollcapable OfIBSlSlZlHQj the rough usage incident to transporting the roll to the placem'hgrefihe rubberized fabric is to be utilized for manufactunng purposes.
