Title: Improvements in machines for producing wire strands
IPC: B21C37/04
Filed: 1936-06-17
Abstract: 474,695. Making electric conductors. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., HUNTER, P. V., and HILL, H. June 17, 1936, No. 16888. [Classes 83 (ii) and 83 (iv)] Rolling.-A stranding-head for the manufacture of pre-spiralled strand for the conductors of multiple electric cables has two roll dies arranged close together, each with a pair of powerdriven rolls, the pairs acting on the strand in relative transverse manner. The rolls are mounted in a rotatable frame in two similar parts bolted together but angularly adjustable. The stranding-head comprises two pairs of roll dies 1, 2 close together. The housing frame 3 is divided transversely into two parts comprising side walls 4 united at each end by apertured walls 5. The adjacent ends make a spigot and socket joint 6, and are held relatively adjustable by bolts 7. The outer end walls carry hollow trunnions housed in bearings 10 in pedestals 11. Each trunnion of the head is driven from a shaft 12 by chain gearing 13, 14. The rolls are interchangeable and are detachably mounted on shafts 15 in bearings 16 in the extremities of the limbs of U-shaped members 17 in slots 18 in the walls. In the case of each pair of rolls, one is fixed, and one is adjustable in a slot 18 by a set-screw 23 in a cap member 22. Rotation of each roll is caused by rotation of the head and is effected through fixed bevel gear-wheels 25 and toothed gearing as shown. Slipping couplings are provided at 26. The spur wheels 28, 29 may be changed to vary the relative speeds of the rolls and head. The stranding-head shown forms a pre-spiralled strand of sector shape for a three-core cable. The compound wires, of circular section, are led through a preliminary shaping die 33, then through the rear trunnion, through a second shaping die 34. The shape of the pairs of rolls is shown in Figs. 3, 4. The shaft 12 carries an adjustable coupling 40, which is not required if the head is driven from one end only. With oval conductors, one pair of rolls compress the strands along the inner axis of the ellipse, and the other along the major axis. The shaft of one roll may be driven from the shaft of another roll. Specification 354,927, [Group XXV], is referred to.
