Abstract

A card controlled machine is provided for automatically lacing, into cable form, a plurality of strands which are arranged in a toothed clamping fixture. The latter retains and aids in compressing the strands during the lacing operation. The successive steps of the operation are illustrated in drawings A through H.

Cable Lacing Machine

A card controlled machine is provided for automatically lacing, into cable form, a plurality of strands which are arranged in a toothed clamping fixture. The latter retains and aids in compressing the strands during the lacing operation. The successive steps of the operation are illustrated in drawings A through H.

The lacing assembly 1 including a hollow shuttle 2 and a gripper element 3
(A) is positioned under card control with respect to the teeth 4 of a clamping fixture 5 between which a lace is to be installed. The lacing assembly is lowered into position (B) and the hollow shuttle 2, threaded with a plastic coated lacing 6, is moved under the cable strands 7 and between the fixture teeth 4 to insert the lace 6 into the gripper 3.

The shuttle 2 is retracted and the assembly is raised to its original position
(C) above the clamping fixture 3. The lacing assembly is then rotated 180 degrees (D) to form a loop in the lacing and is then lowered until the lacing is drawn tightly around the strands.

A welding head 8 (F) is lowered from within the lacing assembly to the cross- point of the lacing loop. The plastic coated lacing is fused together by a welding process utilizing the principal that energy is absorbed by a dielectric in a varying electric field. The teeth 4 act as one plate of a capacitor and the welding element 8 acts as the other, while the lacing 6 acts as the dielectric between the two plates. After welding, the tension on the e...
