Abstract
Abstract A machine for continuous stranding and cabling, for the manufacture of a cable from single wires, the machine including a stranding battery provided with a plurality of single-twist or double-twist delivery stranding spindles, a double-twist cabling device, which includes means for winding up the cable located after the stranding battery, and two twisters associated with the cabling device. Traction means are provided for the strands and for the cable, with two traction stages, one at the stranding stage and one at the cabling stage. The peripheral or drive speed of the traction means at the stranding stage is equal to or greater than the peripheral speed of the traction means at the cabling stage, whereby the tension upstream of the cabling means is reduced.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
149 words
A machine for continuous stranding and cabling for the manufacture of a cable from single wires comprising (A) a stranding battery including a plurality of delivery spindles; (B) double-twist cabling means including a substantially horizontal spindle, a fixed cradle, a winding station on said fixed cradle, and cabling guide means for guiding the cable along a double-twist path about said fixed cradle; (C) traction means including first drive means engaging said strands and second drive means engaging the cable, and means for correlating the speeds thereof so that the speed of the first drive means is at least equal to the speed of the second drive means; (D) a first twister intermediate said stranding battery and the inlet of said double-twisted cabling means; and (E) overtwist means including a twister on said fixed cradle and positioned coaxially with said spindle to receive the cable from said cabling guide means.
Claim 2
Dependent Claim
149 words
A machine for continuous stranding and cabling for the manufacture of a cable from single wires comprising (A) a stranding battery including a plurality of delivery spindles; (B) double-twist cabling means including a substantially horizontal spindle, a fixed cradle, a winding station on said fixed cradle, and cabling guide means for guiding the cable along a double-twist path about said fixed cradle; (C) traction means including first drive means engaging said strands and second drive means engaging the cable, and means for correlating the speeds thereof so that the speed of the first drive means is at least equal to the speed of the second drive means; (D) a first twister intermediate said stranding battery and the inlet of said double-twisted cabling means; and (E) overtwist means including a twister on said fixed cradle and positioned coaxially with said spindle to receive the cable from said cabling guide means.
Claim 3
Dependent Claim
17 words
A machine as claimed in claim 1, and further including lapping means associated with the cabling unit.
Claim 4
Dependent Claim
31 words
A machine as claimed in claim 1, wherein the stranding battery includes aligned vertical double-twist spindles carrying bobbins of single wire and means for regulating the delivery tension of the wires.
Claim 5
Dependent Claim
21 words
A machine as claimed in claim 1 including means for regulating the direction and speed of rotation of said first twister.
Claim 6
Dependent Claim
15 words
A machine as claimed in claim 1, wherein the cabling guide means includes double loops.
Claim 7
Dependent Claim
34 words
A machine as claimed in claim 5, wherein guide means which allow the twist to run back are located at the inlet and outlet of the cabling guide loop through which the cable travels.
Claim 8
Dependent Claim
24 words
A machine as claimed in claim 2, wherein the lapping means includes a lapping spindle mounted on the fixed cradle coaxially with the spindle.
Claim 9
Dependent Claim
28 words
A machine as claimed in claim 1, wherein the second drive means of the traction means includes a capstan mounted on the fixed cradle of the cabling spindle.
Claim 10
Dependent Claim
21 words
A machine as claimed in claim 8, wherein the first drive means includes a single capstan for all the stranding spindles.
Claim 11
Dependent Claim
19 words
A machines as claimed in claim 8, wherein the first drive means includes a capstan for each stranding spindle.
Claim 12
Dependent Claim
54 words
A machine as claimed in claim 1, wherein the speed of the first driven means is greater, by between 1 and 10%, than that of the second drive means. (E) overtwist means including a twister on said fixed cradle and positioned coaxially with said spindle to receive the cable from said cabling guide means.
Claim 13
Independent Claim
70 words
The method of forming cable from individual wires comprising stranding a plurality of said wires to form a plurality of strands; assembling and advancing a plurality of said strands; p1 imparting the selected final twist to the associated strands while cabling the strands in a double-twist loop cabling step; overtwisting the cable within the zone defined by the loop to stabilize the selected final twist; and winding the finished cable.
Claim 14
Independent Claim
70 words
The method of forming cable from individual wires comprising stranding a plurality of said wires to form a plurality of strands; assembling and advancing a plurality of said strands; p1 imparting the selected final twist to the associated strands while cabling the strands in a double-twist loop cabling step; overtwisting the cable within the zone defined by the loop to stabilize the selected final twist; and winding the finished cable.
Claim 15
Dependent Claim
26 words
The method of claim 12 including advancing said assembled strands at a speed slightly in excess of the speed of the cable in the cabling step.
Claim 16
Dependent Claim
13 words
The method of claim 13 including the step of pre-forming said assembled strands.
Claim 17
Dependent Claim
28 words
The method of claim 14 in which the assembled strands are advanced at a speed between 2% and 6% in excess of the speed in the cabling step.
