Abstract: 701,329. Winding and measuring fabrics. CANET, R. M. A. May 31,1951 [June 2, 1950], No. 12996/51. Class 42 (2) A machine-for simultaneously making-up a plurality of ribbons in so-called " English style," or on rolls, cards or the like, comprises means for positioning and moving the ribbons in flat formation under constant tension and with a constant spacing between them, the ribbons being moved by two revolvable heads, at least one of which is mounted yieldingly to allow its moving towards the other, and to hold fast between driving plates, provided on the heads, a carrier arranged axially of the heads, and on which the ribbons are to be finally made up. As shown, the skeins of ribbon are unwound from reels comprising spools 2, 2a, urged apart by elastic links 4, the pivot 3 of the upper spool being suspended from horizontal arms 6, which are slidable in slots in a member 7 secured to an upright on the frame 1, and located by bosses 13 engaging in V-shaped slots 9 or 10. The ribbons 5 then pass over a rod 14, a roller 15, and a rod 16 to a separating device 17 comprising a plate and a number of rocking members, those beneath a given ribbon being depressed thereby, whereas those on either side remain to form lateral guides. They then pass over measuring rollers 27, associated with a revolution counter, over a separating device 28 similar to the one 17, over a clamping ruler 29, and past cutters or trimmers, being finally wound on members supported between plates 36, 36a. The plates 36 and 36a are geared together and are rotated by an electric motor 37 through worm gearing 39, 40 and chain and sprocket transmission, the plate 36a being biased towards the plate 36 by a spring. The clamping ruler 29 consists of a hollow beveledged ruler, incorporating rubber pads, and a top member which may be engaged therewith to clamp the ribbons. In the position shown in Fig. 1, it is used in open condition, but when the winding support is changed, it is closed to clamp the ribbons, clipped on the next winding support, and replaced by another open ruler. When making-up the ribbons on cards, the cards are traversed after a given number of turns, by connecting the plate 36, through a fork 72 (Fig. 22) to a block 60, through which passes a threaded rod 57, which is engaged by a releasable split threaded sleeve 58 ; rotation of the rod 57 causes compression of a spring 63 positioned between the sleeve 58 and the block 60, which is restrained by the engagement of a blade extending from one of a series of stops 62 by spring-biased blades 64, pivoted in the block 60. The blades 64 are released from a stop 62 after a predetermined number of turns by the movement, by a projection on the shaft of a wheel 74, which is driven stepwise by a projection rotating with the shaft of the plate 36, of a lever 69, having a cam surface on its end, which engages a ball 68 acting on the blades 64 causing them to disengage the stops 62, the block 60 then moving under the action of the spring 63 until spring abutments 71 contact the next stop 62. The inertia of the ball 68 carries it forward allowing the blades 64 to re-expand and engage the blade extending from this stop. Alternatively, a hand-operated device for moving the plate 36 by means of a wedge, may be employed. Modifications of the ribbon supply and takeup means to permit two ribbons to be wound simultaneously in each lane, and to permit the interleaving of paper, are described.
