1,170,508. Winding and reeling. GENERAL CABLE CORP. 28 Feb., 1967 [28 Feb., 1966], No. 9373/67. Heading B3E. Wire coiling apparatus includes a capstan on which the wire is wound by a feed roll mounted on a carrier, one of the capstan and the carrier rotating with respect to the other, the said other being capable of turning in response to tension in the wire, under restraint. Wire 24 from a driven capstan 16 passes over guide sheaves 68 and down a hollow rotating shaft 38 to the lower end of which is secured a flyer 40. The wire then passes over rolls 92, 88, 94 and 90 on the flyer 40 to a V- groove in a capstan 70 to lie therein for an arc of 90 degrees, the wire then passing over a roll 98 and under a casting roll 100 on the flyer 40 back into the groove in the capstan 70 to lie therein for an arc of 270 degrees the last 90 degrees of which it lies under the previous 90 degrees lay of wire. The wire then falls in coils on to a receiver 116. The flyer 38, 40 is driven by a pulley 42, variable pulley 46, pulley 60 and pulley 64 on the capstan 16, the variable pulley being so adjusted by screw means 53 that the speed of the shaft 38 exceeds the speed of the capstan 16. The resultant tension in the wire being coiled produces a turning moment on the capstan 70 which rotates slowly in response, being secured to a brake drum 74 engaged by a brake band 78, coils smaller than the capstan 70 thus being produced. The speed of the shaft 38 and flyer 40 can be varied cyclically, to produce a bundle containing cyclically varying coil sizes, by turning the screw 53 by electromechanical means to vary the pitch of the pulley 46. In a modification, Fig. 8 (not shown) the coil receiver may be adjusted eccentrically and be rotated slowly from the braked capstan to produce a patterned bundle. In another modification, Fig. 9, a flyer 340 carries straightening rolls and the coils are directed by an eccentric guide 400, slowly rotated by a braked capstan 370, to a receiver 316. Coil catcher fingers 420 provided on the guide 400 retain a coil temporarily while a full receiver 316 is replaced by an empty one.
