Abstract
Abstract Cabling device has means for twisting strand elements into respective twisted units having a twist direction which varies from section to section thereof (alternate-reverse twist), and means for simultaneously twisting a plurality of such twisted units into a twisted group also having a twist direction varying from section to section thereof. This two-stage cabling operation is effected by the aid of accumulators. Between the two twisting stages, i.e. the twisted unit-forming means and the twisted group forming means, at least one pulling device is disposed, the pulling device being revolvable about an axis corresponding to the axis of the twist of the twisted units and the twisted group.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
88 words
Cabling device comprising a first twisting stage for twisting strand elements into respective twisted units having a twist direction varying from section to section thereof, a second twisting stage for simultaneously twisting a plurality of said twisted units into a twisted group also having a twist direction varying from section to section thereof, said first and said second twisting stages each including an accumulator and a pulling device disposed between said first and said second twisting stages and revolvable about the axis of twist of said twisted group.
Claim 2
Dependent Claim
88 words
Cabling device comprising a first twisting stage for twisting strand elements into respective twisted units having a twist direction varying from section to section thereof, a second twisting stage for simultaneously twisting a plurality of said twisted units into a twisted group also having a twist direction varying from section to section thereof, said first and said second twisting stages each including an accumulator and a pulling device disposed between said first and said second twisting stages and revolvable about the axis of twist of said twisted group.
Claim 3
Dependent Claim
36 words
Cabling device according to claim 1 wherein said pulling device is common to all of the twisted units and is revolvable at the same speed and in the same rotary direction as said second twisting stage.
Claim 4
Dependent Claim
52 words
Cabling device according to claim 2 whereIn said second twisting stage includes separately revolvable input and output parts of the twisted units being twisted into a twisted group, said pulling device being revolvable at the same speed and in the same rotary direction as said input part of said second twisting stage.
Claim 5
Dependent Claim
23 words
Cabling device according to claim 3 wherein said pulling device is firmly connected mechanically to said input part of said second twisting stage.
Claim 6
Dependent Claim
19 words
Cabling device according to claim 2 wherein said pulling device is firmly connected mechanically to said second twisting stage.
Claim 7
Dependent Claim
64 words
Cabling device according to claim 1 wherein said second twisting stage is revolvable at constant rotary speed and comprises a plurality of rollers for guiding the twisted units in a given travel direction therethrough, said pulling device being a roller located upstream of and being revolvable with said plurality of guiding rollers, said pulling device roller being in the form of a pulling sheave.
Claim 8
Dependent Claim
72 words
Cabling device according to claim 1 including a take-up drum located downstream of said second twisting stage and being adapted to be wound by the twisted group twisted from the plurality of twisted units, said take-up drum being rotatable with constant torque, and said pulling device located upstream of said second twisting stage being operable so as to determine the speed at which the strand elements are pulled through the cabling device.
