Abstract
Abstract A ribbon, preferably made of polytetrafluoroethylene and preferably in an unsintered configuration but having lens or trapezoidal cross section is used for wrapping elongated stock such as electrical conductors, tubes, or a removable mandrel, the wrapping to be made with overlapping edges followed by fusion to obtain a coherent tubular configuration.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
108 words
A conductor or cable having a cover comprising a helically wrapped, and thereby stretched, ribbon made of an unsintered powdery or granular synthetic, not amenable to working from a melt but having high temperature resistivity and being thicker in a central portion with tapering edges of reducing thickness and smooth surface, said ribbon having a thickness in its central area from 30 to 200 micrometers and a thickness at the edge region of 5 micrometers and less, adjacent loops of the wrapping overlapping at adjoining tapering edges, thermal sinter treatment subsequent to wrapping having caused fusing of the overlapping edges to result in an overall approximately smooth surface.
Claim 2
Dependent Claim
108 words
A conductor or cable having a cover comprising a helically wrapped, and thereby stretched, ribbon made of an unsintered powdery or granular synthetic, not amenable to working from a melt but having high temperature resistivity and being thicker in a central portion with tapering edges of reducing thickness and smooth surface, said ribbon having a thickness in its central area from 30 to 200 micrometers and a thickness at the edge region of 5 micrometers and less, adjacent loops of the wrapping overlapping at adjoining tapering edges, thermal sinter treatment subsequent to wrapping having caused fusing of the overlapping edges to result in an overall approximately smooth surface.
Claim 3
Dependent Claim
21 words
A wrapping on a cable, or conductor as in claim 1, said synthetic being a polymer containing fluorine, preferably polytetrafluor polymer.
Claim 4
Dependent Claim
27 words
Wrapping on a cable or conductor as in claim 1, wherein the edge width for overlapping and of reducing cross-sectional thickness is between 5 and 50 millimeters.
Claim 5
Dependent Claim
45 words
Wrapping as in claim 1 wherein said cable or conductor is an auxiliary support, there being a plurality of layers of such ribbons whose overlapping edges having been fused subsequent to wrapping to obtain a self-contained tubular configuration from which the support can be removed.
Claim 6
Dependent Claim
18 words
Wrapping on a cable or conductor as in claim 1 wherein said ribbon has a lens-shaped cross section.
Claim 7
Dependent Claim
18 words
Wrapping on a cable or conductor as in claim 1 wherein said ribbon has a trapezoidal cross section.
Claim 8
Dependent Claim
17 words
Wrapping on a cable conductor as in claim 1 wherein said ribbon has very flat declining edges.
Claim 9
Dependent Claim
74 words
Wrapping ribbon made of a temperature-resisting synthetic material not amendable to be worked from a melted consistency and having a cross section deviating from a rectangular configuration by a thicker central portion tapering toward the edges in a curved or straight configuration to assume a lense-shaped or trapezoidal cross section, the surface being smooth throughout, wherein the central portion is 30 to 200 micrometers thick, the edge thickness being not more than 5 micrometers.
Claim 10
Dependent Claim
74 words
Wrapping ribbon made of a temperature-resisting synthetic material not amendable to be worked from a melted consistency and having a cross section deviating from a rectangular configuration by a thicker central portion tapering toward the edges in a curved or straight configuration to assume a lense-shaped or trapezoidal cross section, the surface being smooth throughout, wherein the central portion is 30 to 200 micrometers thick, the edge thickness being not more than 5 micrometers.
Claim 11
Dependent Claim
27 words
Ribbon as in claim 8, wherein the central portion is 30 to 200 micrometers thick at a total width of the ribbon from 4 to 50 mm.
Claim 12
Dependent Claim
26 words
Ribbon as in claim 8, the central portion being from 60 to 180 micrometers thick, the width of the ribbon being from 10 to 30 mm,
Claim 13
Dependent Claim
12 words
Ribbon as in claim 8, the material being a high temperature synthetic.
