Abstract
A mandrel for use in a strander assembly includes a mandrel body having a forward radiused end and an axial cable core receiving passageway extending from a rearward to a forward end of the mandrel body. A cable core is routed through the mandrel body and one or more strands are positioned to converge on the mandrel radiused end. The strands engage the mandrel radiused end at a common approach angle and follow the radius of the mandrel forward end to intersect the cable core. Rotation of the strands relative to the cable core wraps the strands about the cable core, resulting in a finished wound cable construction.
Claims20
A mandrel for use on a strander assembly for winding at least one secondary strand about a primary cable core, comprising:
- a mandrel body having a forward radiused end for operably engaging and directing the secondary strand against the radiussed end to an axial cable core exit opening extending from within the mandrel body through the mandrel body forward radiused end;
- and
- an axial cable core receiving passageway extending through the mandrel body from a rearward to the forward end of the mandrel body.
A strander assembly comprising:
- a pulling mechanism for axially advancing a cable core and secondary strands;
- a guide mechanism for axially directing at least one secondary strand toward the cable core at an approach angle;
- means for rotating the at least one secondary strand about the cable core;
- a mandrel body disposed at a forward end of the strander assembly, the mandrel body having a forward radiused end for operably engaging and guiding the at least one secondary strand to a cable core exit opening extending from within the mandrel body through the radiused end of the mandrel body;
- and an axial passageway extending from a rearward to the forward end of the mandrel body dimensioned to axially receive the cable core therethrough.
