US 10,793,978 B2 · Workstation of a two-for-one twisting or cabling machine

Abstract

A workstation (1) of a two-for-one twisting or cabling machine which comprises a rotatably mounted spindle (2) and a balloon-yarn-guide-eye (9) height-adjustable by means of a drive (18, 29) coupled to a control device (20) which controls the drive (18, 29) in such a manner that it displaces the balloon-yarn-guide-eye (9) between operating positions (AP1, AP2) dependent upon production parameters and a resting position (RS) advantageous in the case of production interruptions and transient operating phases associated with the latter. A device (21, 23, 24, 25) is present for detecting a measured value (i), which is made available to the control device (20) and which causes the control of the drive (18, 29) to change the position of the balloon-yarn-guide-eye (9).

Dependent claims

An individual workstation of a two-for-one twisting or cabling machine which comprises a rotatably mounted spindle and a balloon-yarn-guide-eye height-adjustable by a drive,

characterized in that,
the drive is coupled to a control device, which controls the drive in such a manner that it displaces the balloon-yarn-guide-eye between operating positions dependent upon production parameters and a resting position advantageous in the case of production interruptions and transient operating phases associated with the latter, and
that a device for detecting a measured value (i) is present, which is made available to the control device and causes the control of the drive to change the position of the balloon-yarn-guide-eye,
wherein the balloon-yarn-guide-eye is separately controlled by the individual workstation.
