FIELD: electricity.
SUBSTANCE: backward pull mechanism 1 for twisting of paired electrical wires 1 comprises a pair of clamps 2 for electrical wires, a pair of movable plates 3 in the base to which a pair of clamps for electrical wires is fixed respectively, the common fixed plate 5 in the base with which the pair of movable plates comes into contact with potential sliding in longitudinal direction along the respective guide paths 4, a pair of pneumatic cylinders with potential automatic unclamping of electrical wires fixing by clamps and a pair of pneumatic cylinders 6 for application of backward pull, which connect the common fixed plate with the pair of movable plates in the base.
EFFECT: invention allows excluding wire sagging even in case of deviation in their length during manufacturing of twisted-pair cables.
