Abstract

A cable-stranding apparatus includes a stationary guide, a motor, a driven guide, and a controller electrically coupled to the motor. The stationary guide is configured to guide strand elements in a spaced-apart configuration and to pass a core member. The motor is operatively associated with a guide driver. The driven guide is disposed at least partially within the guide driver so as to rotate therewith. The driven guide is configured to receive the strand elements from the stationary guide, individually guide the strand elements received from the stationary guide, and to further pass the core member. The controller is electrically coupled to the motor and configured to control the rotational speed and direction of the motor.

Dependent claims

An SZ cable-forming system comprising:

a plurality of strand storage containers, each container holding a cable strand element;
a strand guide device for collecting and distributing the plurality of cable stranding elements;
an SZ cable-stranding apparatus comprising:
a rotatable drive shaft defining an axial shaft hole therein;
a guide member disposed in the axial shaft hole, wherein the guide member is fixed to the drive shaft so as to rotate therewith;
and
a positional feedback device that provides information about the rotational position of the guide member;
and
inductively-driven rotors that surround and are configured to drive rotation of the drive shaft;
wherein the SZ-cable stranding apparatus is configured to receive the plurality of cable strand elements from the strand guide device and perform SZ-stranding of the plurality of cable strand elements to form an SZ-stranded assembly;
and
a coating unit configured to receive the SZ-stranded assembly from the SZ cable-stranding apparatus.
