A gripper for electrical or optical lines (24, 24’) such as wires, cables, line bundles, optical fibres has two gripper jaws (22, 22’) which can be moved relative to a counterbearing by means of a drive arrangement as well as rela-tive to one another. Typically twisting heads (4) for twisting apparatuses for the said lines (24, 24’) are equipped with such grippers. The gripper and therefore also the twisting head (4) and the twisting appa-ratus are provided with a drive arrangement which comprises at least one drive (17) with adjustable force, which acts via a link chain (15, 19, 19‘, 20, 20’) on the or each gripper jaw (22, 22‘). The link chain (15, 19, 19‘, 20, 20‘) in this case has a section (19, 19’) which is movable parallel to the drive (17) but in the opposite direction of move-ment. (Fig. 1) |
