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.

Cable stranding apparatus employing a hollow-shaft guide member driver

A cable-stranding apparatus for performing SZ-stranding of strand elements about at least one core member is disclosed. A first stationary guide member individually guides the strand elements in a spaced apart configuration and centrally passes the at least one core member. At least one hollow-shaft motor is arranged downstream of the stationary guide member. A rotating guide member is disposed in the hollow shaft and rotates with the hollow shaft according to a rotation relationship. The rotation relationship controls the rotational speed and direction of the rotating guide member to SZ-strand the strand elements about the at least one core member to form an SZ-stranded assembly. Embodiments of cable-stranding apparatus having multiple hollow-shaft motors and respective multiple rotating guide members are also disclosed.

Cable-stranding methods for performing SZ-stranding of strand elements about at least one core member are disclosed. One method includes passing initially spaced apart strand elements through peripheral guide holes and passing at least one core member through a generally central location of at least one guide member. The method also includes actuating a controller that controls the rotation of the at least one guide member and rotating the at least one guide member to form the SZ-stranded assembly.

Cable stranding methods employing a hollow-shaft guide member driver

The present invention includes systems and methods for monitoring the spooling area of a rotatable reel for winding or unwinding an elongated material, for example, a cable. The monitoring system has a detector for sensing the presence and position of a cable surface or object or operator positioned between the detector and the reel. The detector can control rotation of the reel directly, or send a position signal to a computer where the position signal indicates the detected presence and/or position. The computer can have a memory and/or a processor for respectively storing and analyzing the position signal. The computer is operative to compare the position signal to previously received position signals to determine a condition, for example, the amount of cable on the reel, the presence of any object, and/or the existence of a safety-threatening condition. The computer can generate an output signal for use in, for example, controlling the reel speed and/or torque, or the application of brakes.
