Apparatus for rotating a set of carriers for a strand supply bobbin relative to moving strands from a set of contra-rotating carriers for a strand supply bobbin

摘要

Apparatus for rotating a set of braiding machine front strand carriers around the front side of a first table carrying a set of contra-rotating rear strand carriers on the rear side. Strands from the rear carriers pass through arcuate slots in the first table. A second table is in front of the first table. The tables rotate in opposite directions. The apparatus of the invention has a shuttle for mounting each front carrier, with an arcuate slide tang having a length less than the distance between any two first table slots and carrying a radially inner drive block with two actuator slots. A circular shuttle mounting track carried on the first table front side has inner and outer roller segments between any two first table slots engaging the shuttle slide tangs. A circular actuator cam track carried on the first table has a set of inwardly directed V's with an apex inwardly of an inner end of each table slot. A set of shuttle drive assemblies is mounted on the rear side of the second table. Each drive assembly has two symmetrical and articulated drive arms extending laterally from a single actuator post. Each drive arm follows the cam track and carries an actuator dog for articulated movement into and out of driving engagement with a shuttle drive block actuator slot; so that rear carrier strands positioned at the inner end of each table slot pass between front strand carriers and drive assemblies.
