Abstract
A machine for continuous stranding and cabling, for the manufacture of a cable from single wires, the machine including a stranding battery provided with a plurality of single-twist or double-twist delivery stranding spindles, a double-twist cabling device, which includes means for winding up the cable located after the stranding battery, and two twisters associated with the cabling device. Traction means are provided for the strands and for the cable, with two traction stages, one at the stranding stage and one at the cabling stage. The peripheral or drive speed of the traction means at the stranding stage is equal to or greater than the peripheral speed of the traction means at the cabling stage, whereby the tension upstream of the cabling means is reduced.
Claims15
A machine for continuous stranding and cabling for the manufacture of a cable from single wires comprising
- (A) a stranding battery including
- a plurality of delivery spindles;
- (B) double-twist cabling means including
- a substantially horizontal spindle,
- a fixed cradle,
- a winding station on said fixed cradle, and
- cabling guide means for guiding the cable along a double-twist path about said fixed cradle;
- (C) traction means including first drive means engaging said strands and second drive means engaging the cable, and
- means for correlating the speeds thereof so that the speed of the first drive means is at least equal to the speed of the second drive means;
- (D) a first twister intermediate said stranding battery and the inlet of said double-twisted cabling means;
- and
- (E) overtwist means including a twister on said fixed cradle and positioned coaxially with said spindle to receive the cable from said cabling guide means.
The method of forming cable from individual wires comprising
- stranding a plurality of said wires to form a plurality of strands;
- assembling and advancing a plurality of said strands;
- p1 imparting the selected final twist to the associated strands while cabling the strands in a double-twist loop cabling step;
- overtwisting the cable within the zone defined by the loop to stabilize the selected final twist;
- and
- winding the finished cable.
