Abstract
Abstract Described is a high-flex insulated electrical cable (11) for the carriages of flat knitting machines, this cable having two concentric multi-strand twisted layers (12, 13) each of which is comprised of a plurality of insulated individual strands (17) laid in long lay at the same twist angle. To enable a cable (11) of this nature to resist torsional stresses to an increased degree while retaining its shape and also to give it an extended length of life despite such torsional stresses, the individual strands (17) of each layer (12, 13) have an outer peripheral layer of resiliently deformable soft plastic (18, 19) injected therearound which penetrates into the gussets (22) which are formed between the individual strands (17).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
118 words
A high-flex insulated electrical cable, comprising: a plurality of multi-strand layers, arranged concentric with one another, disposed in long lay at the same angle of twist, each layer having a plurality of twisted strands arranged adjacent to one another, with each said strand defining an outer peripheral area and with adjacent said strands defining a gusset region between them, and a resiliently deformable soft plastic injection coating for each layer, each said coating extending over the outer peripheral areas into the gusset regions defined by the strands of its respective said layer, said resiliently deformable soft plastic coatings being sufficiently resiliently deformable so as not to obstruct the extension or compression of the cable during torsional stressing thereof.
Claim 2
Dependent Claim
118 words
A high-flex insulated electrical cable, comprising: a plurality of multi-strand layers, arranged concentric with one another, disposed in long lay at the same angle of twist, each layer having a plurality of twisted strands arranged adjacent to one another, with each said strand defining an outer peripheral area and with adjacent said strands defining a gusset region between them, and a resiliently deformable soft plastic injection coating for each layer, each said coating extending over the outer peripheral areas into the gusset regions defined by the strands of its respective said layer, said resiliently deformable soft plastic coatings being sufficiently resiliently deformable so as not to obstruct the extension or compression of the cable during torsional stressing thereof.
Claim 3
Dependent Claim
