Problems solved by technology

But if the yarn tension in the final stage exceeds the range that can be controlled by the yarn tensioner, the winding speed is reduced
[0009] The disadvantage of this known method is that the winding speed is reduced prematurely, that is to say, the production capacity of the rewinding operation is not fully used in this known method

Embodiment Construction

[0019] At each station, a yarn 2 is withdrawn from a yarn feed package 1, especially a bobbin produced on a ring spinning machine, which is wound onto a cross-winding package 3, for example a conical cross-winding package . The cross-wound bobbin 3 held by means of a rotatable creel (not shown) rests against a winding roll 4, in particular a so-called grooved roll, by means of which the cross-wound bobbin 3 is rotated and the yarn 2 The cross-wound bobbin 3 is supplied in a reciprocating manner in the axial direction. However, it is also conceivable within the scope of the invention to directly drive the cross-winding bobbin and to use another type of yarn traverse, for example a so-called finger yarn guide. On the way from the yarn feeding bobbin 1 to the cross-winding bobbin 3, the yarn 2, generally formed on a ring spinning machine, passes through a yarn guide 5, a controlled yarn tensioner 6, a yarn tension sensor 9 and a A sensor in the form of a yarn clearer 8 . The y...

Abstract

The invention relates to a method for optimizing the winding speed of a workstation of an automatic winder. A yarn at a workstation is withdrawn from a supply bobbin and wound onto a cross-wound bobbin, wherein the work station controls yarn tension by a yarn tensioner, and the cross-wound bobbin is driven by a driving mechanism capable of controlling rotation speed. An intervention in the winding speed takes place only when a limit for yarn tension control is reached, which means that the yarn tensioner has reached an ultimate opening position and that at least one further so-called offset value is satisfied.In this way, the lowering of the winding speed is delayed. Rewinding at higher winding speed for a long time is allowed, without having to accept lowering in quality.

Description

technical field [0001] The invention relates to a method for optimizing the winding speed of a station of an automatic winder where yarn is drawn from a feed bobbin and wound into a cross-winding bobbin, wherein the station is provided with the aid of The yarn tension of the yarn tensioner is controlled and the cross-winding bobbin is driven by means of a drive mechanism equipped with a speed-controllable drive. Background technique [0002] Textile machines for producing cross-wound bobbins, such as automatic cross-winding winders, are known for a long time and generally consist of a plurality of identical workstations arranged side by side in rows. Each station is equipped with various yarn processing mechanisms or yarn monitoring mechanisms and a station computer, and the station computer is connected with the yarn processing mechanism or yarn monitoring mechanism. The station computers themselves are preferably connected via a bus to the central control of the automatic...
