Method and device for determining or aligning the angular position of individual wires within a sheathed cable containing twisted wires

摘要

A method is disclosed for determining an angular position of individual wires at a predetermined cross-sectional position in a multi-wire sheathed cable, which has, inside a sheath, a plurality of individual wires twisted around one another with a predetermined lay length. The angular position of the individual wires is determined relative to a reference direction, which extends through the central longitudinal axis of the sheathed cable. The method includes: determining an end angle position of the ends of the individual wires relative to the reference direction at an end of the sheathed cable, determining the distance between the end of the sheathed cable and the predetermined cross-sectional position in the longitudinal direction of the sheathed cable, and determining the angular position of the individual wires relative to the reference direction at the predetermined cross-sectional position based upon the end angle position, the lay length, the twist direction, and the distance.

1. A method for aligning a multi-wire sheathed cable containing a plurality of individual wires,
wherein the plurality of individual wires are twisted around one another in a twist direction (+/−) and with a lay length (S), the plurality of individual wires are disposed within a sheath, and a reference direction is perpendicular to a central longitudinal axis of the sheathed cable, the method comprising: determining a desired angle position (β) of at least one of the plurality of individual wires relative to the reference direction at a predetermined cross-sectional position in a longitudinal direction of the sheathed cable, determining a distance (D) between an end of the sheathed cable and the predetermined cross-sectional position in the longitudinal direction of the sheathed cable, calculating a target end angle position (α) of the at least one of the plurality of individual wires relative to the reference direction at the end of the sheathed cable based upon the desired angle position (β) of the at least one of the plurality of individual wires at the predetermined cross-sectional position, the lay length (S), the twist direction (+/−), and the distance (D), and rotating the sheathed cable about its longitudinal axis until the actual end angle position of the at least one of the plurality of individual wires matches the calculated target end angle position of the at least one of the plurality of individual wires.
