Abstract
Abstract To produce a tension-proof and pressure respectively moisturetight uniform sealing of cable ends, a pulling mandrel is driven into the cables end. The pulling mandrel is pointed in the front, becomes constricted in the middle and has the shape of a somewhat truncated cone followed by a cylinder at the rear, where it is possible to construct a thread for screwing on a pulling eye. The cable wires and the cable jacket are pressed together over the constricted portion by means of a tension band.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
A pulling attachment for a cable end of a communications cable wherein said attachment is introduced into the end of a cable and coaxially disposed with respect to the sheath thereof, comprising a mandrel possessing front and rear sections separated by at least one cylindrical middle section of reduced diameter with respect to said front and rear sections, said front section comprising a tapered conical tip expanding to a diameter larger than that of said middle section, and said rear section comprising a truncated cone extending from the reduced diameter of said middle section to a cylindrical rearmost portion, said attachment further comprising at least one tensioning means arranged around said at least one middle section of reduced diameter which presses the wires of the cable against the mandrel at an area of reduced diameter.
Claim 2
Dependent Claim
135 words
A pulling attachment for a cable end of a communications cable wherein said attachment is introduced into the end of a cable and coaxially disposed with respect to the sheath thereof, comprising a mandrel possessing front and rear sections separated by at least one cylindrical middle section of reduced diameter with respect to said front and rear sections, said front section comprising a tapered conical tip expanding to a diameter larger than that of said middle section, and said rear section comprising a truncated cone extending from the reduced diameter of said middle section to a cylindrical rearmost portion, said attachment further comprising at least one tensioning means arranged around said at least one middle section of reduced diameter which presses the wires of the cable against the mandrel at an area of reduced diameter.
