摘要:
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.

A method of manufacturing an electric cable includes winding together two groups in such a manner as to form a group helix, each group having two twisted-together conductor wires, and where the groups are wound together at a speed that varies between two limit speeds having the same sign and in such a manner that the pitch of the group helix varies along the cable between two limit values having the same sign.

A method for producing a tubular underwater pipe including: assembling a structure of peripheral metal elements (3A, 3B, 3C) wound in an S-Z configuration about a central flexible core (1) as the core is driven in movement along its longitudinal axis; providing an inductive sensor (12) arranged for rotation about the central flexible core (1) in a manner synchronized with the longitudinal movement of the core so that the sensor scans the periphery of the structure opposite and in the immediate proximity of peripheral elements wound about the core and during the assembly step; using the sensor (12) to acquire measurement signals (S) of which the amplitude varies according to whether or not the sensor (12) is located opposite a peripheral element during the rotation of the sensor (12); and using the measurement signals to control the positioning of the assembled peripheral elements.

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.

Apparatus for manufacturing a helically-wound electric cable having a winder means for winding two groups, each group having two twisted-together conductor wires, in such a manner as to form a group helix. A means is provided for varying the pitch of the group helix, having two accumulators located respectively upstream and downstream from the winder means, each accumulator having a moving drum enabling a varying length of a central line to be retained. A control means controls the position of each moving drum, where the groups are wound together at a speed that varies between two limit speeds having the same sign and where the winding is in such a manner that the pitch of the group helix varies along the cable between two limit values having the same sign.
摘要:
The present invention relates to a helically-wound electric cable comprising at least two groups that are wound-together so as to form a group helix, each group comprising at least two twisted-together conductor wires. In the cable of the invention, the pitch of the group helix varies along the helically-wound electric cable between two limit values having the same sign.
