Abstract

A production unit for twisted cable is disclosed that facilitates the supply and removal of fixed length cables, thereby contributing to improved workability and automation compatibility. A plurality of pairs of relatively rotatable opposed cable clamps are provided with one cable clamp of each pair provided at one end of the fixed length cables and the other of each pair of cable clamps provided at the other end. Each pair of clamps is intermittently moved forward in a direction transverse to the opposed direction in which the cables extend. Each pair of cable clamps sequentially circulate, and the supply and removal operation of fixed length cables to and from the pairs of clamps are conducted respectively at predetermined positions by stations provided in the circulating route, by which it becomes possible to carry out the supply and removal of fixed length cables to continuously repeat the twisting operation.

Dependent claims

A production unit for twisted cable, including parallel arrangements of a plurality of pairs of opposed cable clamps, the clamps at one side for clamping one end of a pair of fixed length cables and the clamps at the other side for clamping the other end of said pair of cables, each pair of cables extending in a substantially longitudinal direction between a respective pair of cable clamps, with one cable clamp of each pair being driven in rotation by a drive unit, and the other cable clamp of each pair being fixed, thereby giving relative twisting rotation to both cables, further comprising:

a forward movement mechanism provided for intermittently advancing each respective pair of cable clamps in a direction transverse to said substantially longitudinal direction;
a supply station from which said fixed length cables are supplied to each respective pair of cable clamps on the upstream side, and a removing station for removing the pair of fixed length cables from the cable clamp;
and
a rearward movement mechanism for forming an endless form carrying channel with the carrying route formed by said forward movement mechanism and for moving rearwardly the cable clamp previously moved forwardly by said forward movement mechanism.

1 more element

A production unit for twisted cable, comprising:

a cable production unit for providing a plurality of pairs of fixed length cables;
a straightening device for removing deformation from each pair of cables prior to twisting by drawing the fixed length cables which are provided by said production unit;
a delivery unit for delivering each respective pair of fixed length cables from said cable production unit to said straightening device;
parallel arrangements of a plurality of pairs of opposed cable clamps, the clamps at one side for clamping one end of a pair of fixed length cables and the clamps at the other side for clamping the other end of said pair of cables, each pair of cables extending in a substantially longitudinal direction between a respective pair of cable clamps, with one cable clamp of each pair being driven in rotation by a drive unit, and the other cable clamp of each pair being fixed, thereby giving relative twisting rotation to both cables of each said pair of cables;
a forward movement mechanism provided for intermittently advancing each respective pair of cable clamps in a direction transverse to said substantially longitudinal direction;
a rearward movement mechanism for forming an endless form carrying channel with the carrying route formed by said forward movement mechanism and for moving rearwardly the cable clamp previously moved forwardly by said forward movement mechanism;
and
a removing station for removing each pair of fixed length cables from the respective pair of cable clamps after twisting.
