Abstract
Abstract The making of a closed layer from shaped wires on ropes, cables and similar products in which shaped wires are wound on a rope core and in concurrent plastic squeezing of these wires for redistributing their material and changing their profile so that they become reliably interlocked throughout the entire layer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
A method of manufacturing a closed layer on a core such as a wire rope, cable or similar product of wires having a non-round cross-sectional profile shaped to provide gaps between adjacent wires, said profile being selected in accordance with the definite configuration of the core and oriented in a definite manner with respect to the core, the method comprising the steps of applying a layer of wires of approximately the same hardness and essentially identical elongated cross-sectional profile onto the core at a required pitch with the one of the shorter dimensions bearing against the core said gaps being provided between the other shorter sides of adjacent wires, and subjecting the layer to plastic squeezing with the gaps serving for the redistribution of the material of the wires and for altering the profile thereof with at least the degree of interlocking of the wires over thE layer being increased.
Claim 2
Independent Claim
150 words
A method of manufacturing a closed layer on a core such as a wire rope, cable or similar product of wires having a non-round cross-sectional profile shaped to provide gaps between adjacent wires, said profile being selected in accordance with the definite configuration of the core and oriented in a definite manner with respect to the core, the method comprising the steps of applying a layer of wires of approximately the same hardness and essentially identical elongated cross-sectional profile onto the core at a required pitch with the one of the shorter dimensions bearing against the core said gaps being provided between the other shorter sides of adjacent wires, and subjecting the layer to plastic squeezing with the gaps serving for the redistribution of the material of the wires and for altering the profile thereof with at least the degree of interlocking of the wires over thE layer being increased.
Claim 3
Dependent Claim
21 words
The method as claimed in claim 1 wherein a base for making the closed layer is constituted by a removable mandrel.
Claim 4
Dependent Claim
35 words
The method as claimed in claim 1 wherein the wires of the closed layer are of 8-shaped profile with one or two axes of symmetry in its cross-sectional plane, for increasing the degree of interlocking.
Claim 5
Dependent Claim
31 words
The method as claimed in claim 1 wherein the wires of the closed layer are of single- or double-wedge shaped profile, whereby the wires are mutually interlocked over the entire layer.
Claim 6
Dependent Claim
30 words
The method as claimed in claim 1 wherein the rope, cable or similar products with several closed layers are made by subjecting each closed layer in succession to plastic squeezing.
