Abstract

Abstract A cable or cord of a noncircular cross-section composed of a multiplicity of substantially parallel core yarns covered with a textile sheath, the core yarns being bound together and the sheath being bound to the core yarns by means of an adhesive or binder, such cord or cable being characterized in that the noncircular cross-section has at least one axis of symmetry and that, along the entire length of the cord or cable, at least one reinforcing element is present normal to the axis or one of the axes of symmetry, extending over the entire width of the core. Such cables or cords are produced by cross-section, a sheet of parallel core yarns with a binder, disposing the core yarns in the position that they will occupy in the finished noncircular cross-section cable or cord, and covering the core thus formed of parallel core yarns with a sheath, and thereafter vulcanizing the entire assembly, such process being characterized in that the core yarns provide a noncircular cross-section with at least one axis of symmetry and, at the time of formation of the core, reinforcing elements are introduced between the core yarns, such reinforcing elements also being impregnated with a binder, the elements being disposed along the entire length of the cable normal to the axis of symmetry or to one of the axes of symmetry of the core and extending over the entire width of the core at their point of introduction.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 97 words
A novel cable comprising a multiplicity of substantially parallel core yarns constituting a core of a noncircular crosssection, said core being covered by a textile sheath, the bond between the core yarns and said core and sheath being imparted by a binder, said cable being characterized in that said noncircular cross-section has at least one axis of symmetry and said cable contains at least one reinforcing element normal to the axis of symmetry and extending over the entire width of said core at its point of introduction, said reinforcing element extending the entire length of said cable.
Claim 2
Dependent Claim 97 words
A novel cable comprising a multiplicity of substantially parallel core yarns constituting a core of a noncircular crosssection, said core being covered by a textile sheath, the bond between the core yarns and said core and sheath being imparted by a binder, said cable being characterized in that said noncircular cross-section has at least one axis of symmetry and said cable contains at least one reinforcing element normal to the axis of symmetry and extending over the entire width of said core at its point of introduction, said reinforcing element extending the entire length of said cable.
Claim 3
Dependent Claim 14 words
The cable of claim 1 wherein said reinforcing element is composed of a fabric.
Claim 4
Dependent Claim 46 words
The cable of claim 2 wherein said fabric is located in said cable so that its warp is parallel to the longitudinal axis of the cable, elongation to rupture of said fabric being 10-30 percent in the warp and less than 10 percent in the weft.
Claim 5
Dependent Claim 11 words
The cable of claim 1 wherein the noncircular cross-section is elliptical.
Claim 6
Dependent Claim 29 words
The cable of claim 4 wherein said reinforcing elements are normal to the major axis of symmetry of said elliptical cross-section and parallel to the minor axis of symmetry.
Claim 7
Dependent Claim 17 words
The cable of claim 5 wherein one reinforcing element is disposed on the minor axis of symmetry.
Claim 8
Dependent Claim 142 words
A process for the production of a cable composed of a multiplicity of parallel core yarns which comprises: a. impregnating a sheet of parallel yarns with a binder; b. disposing said yarns in the position that they will occupy in the finished cable in a manner so as to produce a core of noncircular cross-section having at least one axis of symmetry; c. at the time of formation of said core introducing between the yarns at least one reinforcing element normal to the axis of symmetry of said core or one of the axes of symmetry of said core and extending over the entire length of said core and over the entire width of said core at the point of introduction; d. covering the core thus formed in step (c) with an outer sheath; and e. vulcanizing the assembly of step (d).
Claim 9
Dependent Claim 142 words
A process for the production of a cable composed of a multiplicity of parallel core yarns which comprises: a. impregnating a sheet of parallel yarns with a binder; b. disposing said yarns in the position that they will occupy in the finished cable in a manner so as to produce a core of noncircular cross-section having at least one axis of symmetry; c. at the time of formation of said core introducing between the yarns at least one reinforcing element normal to the axis of symmetry of said core or one of the axes of symmetry of said core and extending over the entire length of said core and over the entire width of said core at the point of introduction; d. covering the core thus formed in step (c) with an outer sheath; and e. vulcanizing the assembly of step (d).
Claim 10
Dependent Claim 32 words
The process of claim 7 wherein the core produced in step (c) and assembly of step (d) are impregnated with a binder both before and after covering said core with said sheath.
Claim 11
Dependent Claim 29 words
The process of claim 7 wherein at the time of formation of the core electrical conductor elements are introduced so as to extend the entire length of said core.
