A gripper for electrical or optical lines (24, 24′) such as wires, cables, line bundles, optical fibers has two gripper jaws (22, 22′) movable relative to a counterbearing as well as relative to one another. Twisting heads (4) for twisting apparatuses for the lines (24, 24′) are equipped with such grippers. The gripper and the twisting head (4) and the twisting apparatus are provided with a drive arrangement including at least one adjustable-force drive (17) that acts via a link chain (15, 19, 19′, 20, 20′) on gripper jaw (22, 22′). The link chain (15, 19, 19′, 20, 20′) in this case has a section (19, 19′) movable parallel to the drive (17), but in the opposite direction of movement. |

1. A twisting machine comprising:
a hollow cylindrical support structure, said hollow cylindrical support structure having a proximal end, and said hollow cylindrical support structure having a distal end; a shaft connected to said proximal end of said cylindrical support structure; a pressure ring disposed around said shaft, said pressure ring being reciprocatable relative to the shaft along an axis of rotation of said shaft; a plurality of pressure rods extending from said proximal end of said hollow cylindrical support structure, said pressure rods being operatively connected to said reciprocatable pressure ring to reciprocate therewith, said pressure rods extending towards said distal end of said cylindrical support structure; a plurality of respective angle levers each operatively connected with a respective one of said pressure rods at respective locations proximate to said distal end of said support structure, each of said angle levers having a respective first lever-arm end that respectively engages a respective one of said pressure rods; and, a plurality of movable gripper jaws situated proximate to said distal end of said hollow cylindrical support structure, said movable gripper jaws being mounted to controllably reciprocate radially relative to the axis of rotation of said shaft, each of said angle levers having a respective second lever-arm end that respectively engages a respective one of said gripper jaws to provide that controlled reciprocation of said pressure ring along the axis of rotation of said shaft controllably reciprocates said movable gripper jaws radially relative to the axis of rotation of said shaft. |
