Date Oct. 8, 1987.An alternate reverse or so-called SZ-twisting method and apparatus and cable product produced by alternate reverse twisting method and/or apparatus. Elements (2 ) which are to be alternately reversely twisted may be wires, leads, optical fibers, their groups and which can also include quads of wires, leads, optical fibers. Elements (2) to be twisted and a possible core element (9) are drawn from a fixed divider (3), preferably a perforated holeplate, through a twister (6), preferably a perforated holeplate, rotating periodically in opposite directions, to a presser (7), preferably a nipple, in which the elements to be twisted and the possible core element are pressed together, to form an alternately reversely twisted product (8). Between the divider (3) and the twister (6) pipe group (4, 5) is provided for defining the feedpaths of the elements (2) to be twisted and the possible core element (9). The pipe group includes both a centrally located central pipe (5) for defining the feedpath of the possible core element and several peripheral pipes (4) for defining the feedpaths of said elements to be twisted, which peripheral pipes circumferentially surround the central pipe and are periodically twistable in opposite directions around and against the central pipe.
