Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
129 words
In a stranding machine which includes an accumulator for strands, further including means for rotating the accumulator on a stranding axis, and at different particular speeds, there being transition periods during speed changes, there being additionally means for paying strands to be twisted, the improvement comprising: a stranding nipple disposed for positioning and running the strands to be twisted into the axis, to obtain twisting of the strands upon relative rotation between the accumulator and the stranding nipple about the axis; and means for moving the stranding nipple towards the accumulator on the stranding axis and at least approximately during each transition period, said means moving the stranding nipple in the opposite direction on the axis during periods of rotation of the accumulator at each of the particular speeds.

Claim 3
Dependent Claim
60 words
Stranding machine as in claim 1, means for operating the means for moving the stranding nipple towards the entrance of the accumulator at essentially similar speed as the pay-in speed of the strands and during each of the transition periods, said operating means positioning the nipple close to the entrance of the accumulator at the end of each transition period.
Claim 4
Dependent Claim
33 words
Stranding machine as in claim 1, there being a guide plate with plural apertures for guiding individual strands towards the stranding nipple, the guide plate disposed for moving in unison with the nipple.
Claim 5
Dependent Claim
17 words
Stranding machine as in claim 1, there being displaceable strand guiding means disposed between nipple and accumulator.
