Abstract
Abstract Continuous lengths of flat electrical cable have segments of the cable easily strippable for termination purposes. Flat multiconductor cable may be produced by laminating conductors between sheets or ribbons of plastic insulation material. Easily strippable segments of such a cable may be made by interrupting the laminations in the insulating sheets at periodic intervals. The insulating material which has not been laminated may subsequently be cut transversely just prior to end-use application, and pulled away from all conductors simultaneously, thereby exposing all conductors for termination.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
95 words
An easily strippable, flat carbon cable for transmission of electricity, comprising: a. A multiplicity of elongated electrical conductors insulated with a continuous coating of a primary insulation, b. at least two elongated sheets of polymeric electrical insulating material enclosing said multiplicity of insulated conductors, forming a multi-conductor cable, c. said sheets being alternately bonded together in a first longitudinal segment of cable and not bonded together in a second longitudinal segment of cable located adjacent longitudinally to said bonded segment, d. said bonded and non-bonded segments alternating periodically along the entire length of said cable.
Claim 2
Dependent Claim
95 words
An easily strippable, flat carbon cable for transmission of electricity, comprising: a. A multiplicity of elongated electrical conductors insulated with a continuous coating of a primary insulation, b. at least two elongated sheets of polymeric electrical insulating material enclosing said multiplicity of insulated conductors, forming a multi-conductor cable, c. said sheets being alternately bonded together in a first longitudinal segment of cable and not bonded together in a second longitudinal segment of cable located adjacent longitudinally to said bonded segment, d. said bonded and non-bonded segments alternating periodically along the entire length of said cable.
Claim 3
Dependent Claim
41 words
The cable of claim 1 in which at least two of said elongated electrical conductors insulated with primary insulation are twisted together to form a twisted pair, and at least one of said twisted pairs are interposed between said insulating sheets.
Claim 4
Dependent Claim
11 words
The cable of claim 1 in which said sheets are polytetrafluoroethylene.
Claim 5
Dependent Claim
11 words
The cable of claim 1 in which said sheets are polyester.
Claim 6
Dependent Claim
11 words
The cable of claim 1 in which said sheets are polyamide.
Claim 7
Dependent Claim
11 words
The cable of claim 1 in which said sheets are polyimide.
Claim 8
Dependent Claim
11 words
The cable of claim 1 in which said sheets are polyurethane.
Claim 9
Dependent Claim
11 words
The cable of claim 1 in whiCh said sheets are polyvinylchloride.
Claim 10
Dependent Claim
11 words
The cable of claim 1 in which said sheets are polyolefin.
Claim 11
Dependent Claim
13 words
The cable of claim 1 in which said sheets are fluoronated ethylene propylene.
Claim 12
Dependent Claim
19 words
A ribbon cable in accordance with claim 1, the non-bonded segments extending across the entire width of said cable.
Claim 13
Dependent Claim
59 words
A ribbon cable in accordance with claim 1, the non-bonded segments of said insulating sheets extending outwardly from the centerline of said cable toward the edges of said cable but not extending to the edges of said cable, said insulating sheets being bonded together for a distance inward from the cable edges along the entire length of said cable.
Claim 14
Dependent Claim
105 words
A process for making an easily strippable, flat ribbon cable for the transmission of electricity, which process comprises: a. interposing at least one elongated electrical conductor between a pair of elongated sheets of electrical insulating material to form a bondable assembly, b. passing said bondable assembly through the nip formed between two pressure rollers, at least one of which rollers has a depression in its surface, c. thereby bonding said sheets with conductors between where they contact each other in passage through said rolls, but forming no bond between said sheets where said depression is adjacent one of said sheets and relieves the bonding pressure.
Claim 15
Dependent Claim
105 words
A process for making an easily strippable, flat ribbon cable for the transmission of electricity, which process comprises: a. interposing at least one elongated electrical conductor between a pair of elongated sheets of electrical insulating material to form a bondable assembly, b. passing said bondable assembly through the nip formed between two pressure rollers, at least one of which rollers has a depression in its surface, c. thereby bonding said sheets with conductors between where they contact each other in passage through said rolls, but forming no bond between said sheets where said depression is adjacent one of said sheets and relieves the bonding pressure.
Claim 16
Dependent Claim
20 words
The method of claim 13 wherein said bonding is accomplished by introducing an adhesive between the sheets of insulating material.
Claim 17
Dependent Claim
32 words
The method of claim 13 wherein said bonding is accomplished by raising the temperature of said insulating sheets, at their respective surfaces of contact, to the point where said sheets become tacky.
Claim 18
Dependent Claim
29 words
The method of claim 13 wherein said sheets are unsintered polytetrafluoroethylene and said bonding is accomplished by laminating said assembly with the pressure rollers operating to compress said sheets.
