Abstract
Abstract A method of and high speed machine for stranding to form ropes from filaments by feeding filaments from storage spools to a rotary stranding head. Rope issues from the machine in the opposite direction by employing deflector devices associated with guide carriers. The stranding head is rotated in the same direction but at about twice the speed as the guide carriers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
93 words
A method of stranding filaments to form ropes, cores of cables or the like, which comprises the steps of a. feeding the filaments from storage spools towards a junction, b. twisting the filaments into a strand at said junction by rotating said filaments at a predetermined speed in a predetermined plane and axis, and c. deflecting the formed strand in said plane and along said axis in a direction opposite to the feeding direction while rotating the deflected strand at a speed about one-half of the twisting speed of the original rotational speed.
Claim 2
Independent Claim
93 words
A method of stranding filaments to form ropes, cores of cables or the like, which comprises the steps of a. feeding the filaments from storage spools towards a junction, b. twisting the filaments into a strand at said junction by rotating said filaments at a predetermined speed in a predetermined plane and axis, and c. deflecting the formed strand in said plane and along said axis in a direction opposite to the feeding direction while rotating the deflected strand at a speed about one-half of the twisting speed of the original rotational speed.
Claim 3
Dependent Claim
145 words
A high speed stranding machine to form ropes, cores of cables, and the like, in accordance with the stranding method set forth in claim 1, comprising in combination, a. a pair of guide carriers rotatably mounted in said machine, and adapted to rotate about said predetermined axis, b. a spool carrier inertially supported by said pair of guide carriers and adapted to carry a plurality of spools of filaments, c. a pair of deflector devices associated with each guide carrier and mounted in said predetermined plane, d. a stranding device rotatably coaxially mounted in said spool carrier, e. a guide member inertially mounted in said spool carrier for feeding the filaments to the stranding device, and, f. driving means operatively connected to said pair of guide carriers and said stranding device and adapted to rotate the latter at about twice the speed of the former.
Claim 4
Dependent Claim
41 words
A high speed stranding machine as defined in claim 2, comprising a stranding nipple forming the stranding point of the stranding device, and further comprising a roller system for guiding the stranded product in a predetermined path on leaving the nipple.
Claim 5
Dependent Claim
58 words
A high speed stranding machine as defined in claim 2, wherein a guide roller is juxtaposed to at least some of the storage spools so disposed in relation to the guide member that, when the machine is operative, each filament running off from the spool runs into the guide member at an acute angle to the common axis.
Claim 6
Dependent Claim
21 words
A high speed stranding machine as defined in claim 2, wherein the guide member is a perforated and aXially displaceable disc.
Claim 7
Dependent Claim
20 words
A high speed stranding machine as defined in claim 2, wherein the second drive means includes an infinitely variable transmission.
Claim 8
Dependent Claim
24 words
A high speed stranding machine as defined in claim 2, wherein each of the deflector devices is a deflector segment having a guide groove.
