Abstract
Abstract An apparatus for stranding an outer layer of wires on an inner layer cable core is disclosed. The apparatus comprises a tubular stranding machine comprising a rotating tube within which are stationary mounted on the same axis a series of cradles each supporting a spool of wire from which are paid-off the outer wires, means for guiding said outer wires along the outside wall of said tube towards a stranding die located at the front of the stranding machine, means for guiding a cable core originating from the back of the stranding machine along the outside wall of the tube, and a wire straightener stationary mounted at the front of the stranding machine ahead of the stranding die and through which is passed the cable core to eliminate the waviness of the cable core due to rotation during traveling along the outside wall of the tube.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
An apparatus for stranding an outer layer of wires on an inner layer cable core comprising: (a) a tubular stranding machine comprising a rotating tube within which are stationarily mounted on the same axis a series of cradles each supporting a spool of wire from which are paid-off the outer wires; (b) means for guiding said outer wires along the outside wall of said tube towards a stranding die located at the front of the stranding machine; (c) means for guiding a cable core originating from the back of the stranding machine along the outside wall of said tube and then inside the tube through a guiding die located on the same axis as the tube, towards said stranding die; and (d) a wire straightener stationarily mounted on the axis of the tube between the guiding die and the stranding die and through which is passed the cable core to eliminate the waviness of the cable core due to rotation during traveling along the outside wall of the tube.
Claim 2
Independent Claim
169 words
An apparatus for stranding an outer layer of wires on an inner layer cable core comprising: (a) a tubular stranding machine comprising a rotating tube within which are stationarily mounted on the same axis a series of cradles each supporting a spool of wire from which are paid-off the outer wires; (b) means for guiding said outer wires along the outside wall of said tube towards a stranding die located at the front of the stranding machine; (c) means for guiding a cable core originating from the back of the stranding machine along the outside wall of said tube and then inside the tube through a guiding die located on the same axis as the tube, towards said stranding die; and (d) a wire straightener stationarily mounted on the axis of the tube between the guiding die and the stranding die and through which is passed the cable core to eliminate the waviness of the cable core due to rotation during traveling along the outside wall of the tube.
Claim 3
Dependent Claim
27 words
An apparatus as defined in claim 1, wherein the cable core is made of a central wire upon which is stranded at least one layer of wires.
Claim 4
Dependent Claim
29 words
An apparatus as defined in claim 1 or 2, further comprising a spool located at the back of the stranding machine and from which the cable core is paid-off.
Claim 5
Dependent Claim
