Abstract
Abstract Telecommunications cable formed by locating a plurality of conductors in a group in an open array, which is preferably planar, and shaping the group into arcuate configuration around a longitudinal axis with the conductors extending generally in the direction of the axis. A layer of insulation is then provided around the group to hold it in its planar configuration.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
90 words
A method of making a telecommunications cable comprising: disposing a plurality of insulated conductors together into a conductor group in which the conductors are in open planar array in a direction normal to a longitudinal direction of the group and retaining the conductors in their relative positions in the group; shaping the group into an arcuate configuration around a longitudinal axis with the conductors extending in the general direction of the axis; and providing a layer of insulation extending around the axis and surrounding the group in its arcuate configuration.
Claim 2
Independent Claim
90 words
A method of making a telecommunications cable comprising: disposing a plurality of insulated conductors together into a conductor group in which the conductors are in open planar array in a direction normal to a longitudinal direction of the group and retaining the conductors in their relative positions in the group; shaping the group into an arcuate configuration around a longitudinal axis with the conductors extending in the general direction of the axis; and providing a layer of insulation extending around the axis and surrounding the group in its arcuate configuration.
Claim 3
Dependent Claim
42 words
A method according to claim 1, comprising retaining the conductors in open array by the use of a flexible holding material having longitudinally extending side edges, and turning the side edges towards each other to form the material into substantially cylindrical configuration.
Claim 4
Dependent Claim
18 words
A method according to claim 2, wherein the side edges are brought into close proximity with one another.
Claim 5
Dependent Claim
20 words
A method according to claim 3, comprising turning the side edges of the holding material around a longitudinally extending core.
Claim 6
Dependent Claim
22 words
A method according to claim 3, comprising twisting the cylindrical configuration to provide helical paths for the conductors around said longitudinal axis.
Claim 7
Dependent Claim
23 words
A method according to claim 2, wherein a binding tape is wrapped around the cylindrical configuration before the layer of insulation is applied.
Claim 8
Dependent Claim
25 words
A method according to claim 2, wherein the layer of insulation is applied to the insulation by extending polymeric insulating material around the cylindrical configuration.
Claim 9
Dependent Claim
21 words
A method according to claim 7, wherein the layer of insulation is formed with spaced apart holes passing through the insulation.
Claim 10
Dependent Claim
27 words
A method according to claim 2, wherein the holding material is wrapped around itself and around the longitudinal axis to provide at least two layers of conductors.
Claim 11
Dependent Claim
60 words
A method according to claim 2, comprising winding the cylindrical configuration onto a spool while rotating the spool around the longitudinal axis to twist the cylindrical configuration to provide helical paths for the conductors around said longitudinal axis, unspooling the cylindrical configuration while retaining the helical paths of the conductors, and extruding the layer of insulation around the cylindrical configuration.
Claim 12
Dependent Claim
50 words
A method according to claim 2, comprising passing the flexible holding material carrying the conductors through a turning guide to form the material into substantially cylindrical configuration and passing the cylindrical configuration downstream from the guide and extruding a polymeric insulating material onto it to provide the layer of insulation.
Claim 13
Dependent Claim
33 words
A method according to claim 2, comprising providing the flexible holding material as a support tape and retaining the conductors in open array by holding them onto the support tape by an adhesive.
Claim 14
Dependent Claim
28 words
A method according to claim 2, comprising holding the conductors in open array by extruding around them a web of insulating material which provides the flexible holding material.
