Abstract

865,493. Self-coiling cables. WESTERN ELECTRIC CO. Inc. Aug. 15, 1958 [Aug. 29, 1957], No. 26324/58. Drawings to Specification. Class 36. A self-coiling cable is made by twisting the cable to form a helix, setting the helix by heat treatment, reversing the pitch of the helix and at the same time over-twisting the freshlyformed coil, and subsequently removing substantially all' of the over-twist from the cable. The pitch of the helix is preferably reversed by the method described in Specification 536,937.
