Abstract
An apparatus and method are described for producing compact stranded conductors on single and double twist machines. This is achieved by preshaping and metering the preshaped wires to have generally sectored cross-sectional profiled complementary configurations and positioning and orienting the preshaped wires to substantially correspond to their positions and orientations in relation to the core wire in the final compact twisted conductor. The wires are metered to a double twist strander which is used to initially twist the preshaped wires about the core wire in a generally loose construction, and these wires are subsequently locked into abutment against each other when imparted a second twist to form the compact composite conductor.

Apparatus for making twisted compact conductors including a plurality of wires comprising means for providing a plurality of complementary segmented preshaped wires each having a desired cross-sectional profiled configuration in the final compact conductor and each defining at least lateral surfaces;
- means for positioning and orienting the preshaped wires with relation to each other to substantially correspond to the positions and orientations therebetween in the final twisted compact conductor;
- twisting means, downstream of said means for positioning and orienting, for imparting at least one twist to the wires;
- means for feeding the wires to said twisting means at a rate of speed to cause the lateral surfaces of adjacent preshaped wires to substantially abut against each other and to produce the desired lay, whereby interstices between the wires forming the twisted conductor are substantially eliminated to form a compact twisted conductor.
A method of making compact conductors comprising the steps of providing and feeding a plurality of complementary segmented preshaped wires each having a desired cross-sectional profiled configuration in the final compact conductor and each defining at least lateral surfaces;
- positioning and orienting the preshaped wires with relation to each other to substantially correspond to the positions and orientations therebetween in the final twisted compact conductor;
- imparting at least one twist to the wires after the wires have been positioned and oriented, the feeding of the preshaped wires taking place at the rate of speed to cause the lateral surfaces of adjacent preshaped wires to substantially abut against each other and to produce the desired lay of the product, whereby interstices between the wires forming the twisted conductor are substantially eliminated to form a compact twisted conductor.
