Embodiment Construction

[0017] figure 1 A winding machine 1 is shown having a plurality of winding units 2 and a reference winding unit 2' arranged between end frames 55, 56 of the winding machine 1. The winding machine has a central control unit 50 connected via a bus system 60 to a winding unit controller 40 . The central control unit has a keyboard 52 and a display 51 for operation and display.

[0018] figure 2 A schematic side view of the reference winding unit 2' during the winding process is shown. The structures of the winding units 2 are all the same. Only the reference winding unit 2' additionally has a yarn tension sensor 20. At the winding unit 2, the relatively small feed package (commonly called spinning package) 9 produced on the ring spinning machine with only relatively little yarn material is rewound into a bulky cross-wound package 11, due to This is well known and therefore will not be described in more detail. The finished cross-wound bobbins 11 are then transferred b...

Abstract

The present invention relates to a method and a winding machine for operating a winding unit. The yarn tensioning is set by the yarn tensioner (14) and the unwinding accelerator (45) is lowered on the package (9) as the unwinding process progresses. According to the invention, the yarn tension is controlled in a closed-loop manner by means of a yarn tension sensor (20) located in the reference winding unit (2'), wherein the yarn tension is set according to the measured values ​​of the yarn tension sensor (20) a thread tensioner (14) that senses and stores the settings of the thread tensioner (4) at the reference winding unit (2') according to the position of the unwind accelerator (45); and At the winding unit (2), the yarn tensioner (14) is set by the stored value according to the position of the unwinding accelerator (45).

Description

technical field [0001] The present invention relates to a method for operating a winding unit, and more particularly to a method for setting yarn tension. The invention also relates to a winding machine. Background technique [0002] In the case of known winding machines, as described for example in EP 2 468 670 B1, it is possible to control the yarn tension or yarn tension, i.e. relative to the yarn cross-sectional area, in an open-loop or closed-loop manner. Yarn tension. The yarn tension is set via the yarn tensioner. In the case of an open-loop control of the yarn tensioning, no sensor is required and eg a constant control signal is assigned to the yarn tensioner. For closed-loop control of yarn tension, a sensor measuring a quantity representative of yarn tension is required. Sensors known as yarn tension sensors are common. The operator can set whether the yarn tension should be controlled in a closed loop or an open loop. It is wise to specify this setting on a ...
