<p>781,013. Machines for making wire ropes. COOK, J. March 8, 1955 [March 19, 1954], No. 6812/55. Class 109 A wire stranding machine comprises a base, a flyer 19. rotatably mounted thereon, a motor 57 and driving connection for rotating the flyer, a reel supporting member coaxial with the flyer to receive a reel and to rotate it relatively to the flyer, means 'for guiding wire strands to and on the flyer and to distribute them on to the reel, and a drive between the flyer and reel supporting member to control positively the relative motion between flyer and reel, and means for varying the ratio of the drive during the winding of wire on to the reel. Wires W from supply spools are led through a spider S into the bore of the shaft 27, thence around a pulley 20 to pulleys 56 on bars 55 of the flyer 19 driven by the motor 57 through pulleys 58 (not shown), 25 and belt 58a. The pulley 25 has attached thereto a pulley 24 which through a belt 63, drives a pulley 62 on a lay shaft 59, the pulley 62 being manually adjustable by a hand wheel 78 or automatically through a worm wheel 68 and shaft 67. The lay shaft 59, which is braked by an electric-type brake 59a when the motor 57 is switched off, through a belt 70 and pulley 71, drives the hollow shaft 36, which, through a dog plate 51 and pins 52 rotates the reel 53 to take up the twisted wires. A further motor 46 (not shown), through a screw, reciprocates the shaft 36 and hence the reel 53 to traverse the gauge.</p> |
