Abstract
Abstract An S-Z twisting machine including a twisting disc operated reversibly at the speed n 1 and a tubular accumulator driven with the lower speed n 2 . The elements to be twisted which are applied to the tubular accumulator via an aperture guide disc, are preferably conducted through a further aperture guide disc which is rigidly connected to the tubular accumulator near its center to insure that the loops before and behind the further guide disc are equal per unit length of the tubular accumulator.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
90 words
In a machine for SZ-twisting by means of a stationary aperture guide disc and a reversibly driven twisting disc, where the elements to be twisted are fed to the twisting disc along a tubular guide and tubular accumulator arranged concentrically to the twisting axis and extending from the aperture guide disc to the twisting disc, the improvement comprising drives for the twisting disc and the tubular accumulator designed so that the tubular accumulator can be driven at a speed of rotation which differs from the speed of the twisting disc.
Claim 2
Dependent Claim
90 words
In a machine for SZ-twisting by means of a stationary aperture guide disc and a reversibly driven twisting disc, where the elements to be twisted are fed to the twisting disc along a tubular guide and tubular accumulator arranged concentrically to the twisting axis and extending from the aperture guide disc to the twisting disc, the improvement comprising drives for the twisting disc and the tubular accumulator designed so that the tubular accumulator can be driven at a speed of rotation which differs from the speed of the twisting disc.
Claim 3
Dependent Claim
37 words
The improvement according to claim 1 wherein a common drive is provided for the twisting disc and the tubular accumulator, and where a transmission is arranged between the drive for the twisting disc and the tubular accumulator.
Claim 4
Dependent Claim
14 words
The improvement according to claim 2, wherein said the transmission is a multi-stage transmission.
Claim 5
Dependent Claim
13 words
The improvement according to claim 2, wherein said transmission is a variable transmission.
Claim 6
Dependent Claim
16 words
The improvement according to claim 1, wherein a separate drive is provided for the tubular accumulator.
Claim 7
Dependent Claim
31 words
The improvement according to claim 1 or 5, wherein said drives are adapted to drive the tubular accumulator so that it rotates with approximately one-half the speed of the twisting disc.
Claim 8
Dependent Claim
28 words
The improvement according to claim 6, and further including a rigid aperture guide disc for the elements to be twisted approximately in the middle of said tubular accumulator.
Claim 9
Dependent Claim
34 words
The improvement according to claim 7, wherein the tubular accumulator and the aperture guide disc rigidly connected thereto are rotatably supported in a stationary pillow block in the vicinity of said aperture guide disc.
Claim 10
Dependent Claim
30 words
The improvement according to claim 8, wherein the drive for the tubular accumulator and the aperture guide disc rigidly connected thereto is arranged in the vicinity of said pillow block.
