Abstract

The present invention refers to a method of twisting at least two individual conductors comprising the following steps: fixing the first conductor ends of individual conductors, which have been cut off to a suitable length, in respective separate untwisting fixation means which are rotatable essentially parallel to a twisting axis; fixing the second conductor ends of said individual conductors in respective separate twisting fixation means which are arranged such that they are adapted to be rotated in common about said twisting axis; arranging a twisting slide between the essentially tensioned conductors; and rotating the twisting fixation means in common about the twisting axis and rotating the untwisting fixation means about the conductor axis of the respective conductors in the same direction. This method aims at achieving a reduced production expenditure for twisted conductors on the basis of more flexible production conditions. In addition, the present invention refers to an apparatus for twisting at least two individual conductors.

A method of twisting at least two individual conductors and operating a twisting apparatus comprising at least two untwisting fixation means (10) used for fixing first conductor ends (33) and arranged such that they are adapted to be rotated separately about an axis of each conductor and substantially parallel to a twisting axis (A), at least two twisting fixation means (8) used for fixing second conductor ends (35) and arranged in opposed relationship with said untwisting fixation means (10) and adapted to be rotated in common about the twisting axis, and a twisting slide (6) which is adapted to be positioned between said conductors (15, 16), said untwisting fixation means (10), and said twisting fixation means (8) being adapted to be moved relative to one another along the twisting axis (A), the method comprising the following steps:

fixing the first conductor ends (33) of individual conductors (15, 16), which have been cut off of a suitable length, in respective separate untwisting fixation means (10) which are rotatable substantially about an axis of each conductor and substantially parallel to a twisting axis (A);
after the fixing of the first conductor ends (33), moving the untwisting fixation means (10) along the twisting axis (A) relative to and away from the twisting fixation means (8) by a specific length so as to insert the conductors (15, 16) into the twisting apparatus;
fixing the second conductor ends (35) of said individual conductors (15, 16) in respective separate at least two twisting fixation means (8) which are arranged such that they are adapted to be rotated in common about said twisting axis (A);
tensioning the conductors;
arranging a twisting slide (6) between the tensioned conductors (15, 16);
and
rotating the at least two twisting fixation means (8) in common about the twisting axis (A) and rotating the at least two untwisting fixation means (10) about the conductor axis of the respective individual conductors (15, 16) in the same direction and coordinated with the rotation of the twisting fixation means so as to prevent torsional loads on the individual conductors.
