Problems solved by technology

[0011] These known bobbin preparation devices have proven in practice to have the disadvantage that they are completely independent of the supply requirements of the downstream automatic cross-winding winders, especially the automatic cross-winding winders Bits work independently of their individual bobbin requirements and independently of the state of the fed bobbins

Embodiment Construction

[0037] figure 1 An exemplary embodiment for the connection between the ring spinning machine 1 and the automatic cross-winding winder 2 is schematically shown in top view.

[0038] The conveyor systems of the two textile machines are connected to one another via a connecting system 30 , as is known and is therefore only indicated schematically with arrows. The conveying system installed in the area of ​​the ring spinning machine is not described in detail because it is known on the one hand and it is not the subject of the present application on the other hand.

[0039] The bobbin-empty bobbin conveying system 12 arranged in the area of ​​the automatic cross-winding winder 2 has various conveying sections as usual, in the illustrated embodiment for example having the bobbin conveying section 3, A bobbin return section 4 , a reversibly drivable accumulator section 5 and a transverse transport section 6 leading to the work station 11 . According to an advantageous embodiment, ...

Abstract

The invention relates to a tube yarn preparation method for applying tube yarns manufactured on a ring spinning frame to subsequent rewinding operation on a working position of an automatic cross winding machine with an automatic tube yarn-tube delivering system. In a tube yarn preparation device, yarn heads are loosened and received in the tube yarn, and are positioned on a standby position; the yarn heads are then re-received in the working position area of the automatic cross winding machine, and the tube yarn rewinding operation is started. The method of the invention specifies that the tube yarn (16) supply of the automatic cross winding machine (2) is monitored by a machine control device (28) of the automatic cross winding machine (2), and when the supply is lower than a predetermined supply threshold, the period productivity of the preparation process of the tube yarn preparation device (10) is increased to obtain improvement of the supply of the automatic cross winding machine (2).

Description

technical field [0001] The invention relates to a method for preparing bobbins produced on a ring spinning machine for subsequent rewinding operations. Background technique [0002] With regard to ring spinning machines, it has long been published and clearly described in numerous patent applications that the cops produced on such textile machines, containing relatively small amounts of They are rewound into cross-wound bobbins before continuing on-machine. The rewinding of such relatively small bobbins into larger cross-winding bobbins generally takes place at the station of an automatic cross-winding winder. [0003] However, since cops produced on ring spinning machines usually have so-called post-windings determined by the way such textile machines work, such cops have to be wound before they reach the station of the automatic cross-winding winder. It is processed in a special bobbin preparation unit. That is to say, at the end of the bobbin stroke in ring spinning ma...
