Problems solved by technology

[0003] This method has proven to be disadvantageous in that fluctuations in the yarn tension for the twisted yarn to be wound caused by the upstream twisting process impair the quality of the cross bobbin to be wound finely

Embodiment Construction

[0021] The present invention will be described in more detail below with reference to the embodiments shown in the drawings.

[0022] figure 1 The single figure in is a schematic diagram of the structural principle of the twisting station 1 of a two-for-one twisting machine with a plurality of similar twisting stations, with the aid of which the method of the invention is described. The twisting station 1 of the two-for-one twisting machine comprises a twisting spindle 2 driven by a single-motor spindle drive 3 . The twisting spindle 2 comprises bobbins, bobbin brakes, storage discs on the twisting plate and replaceable yarn guides, such as deflection elements on the storage discs and eyelets on the bobbin brakes, the structure of which guides on their surface And its quality aspect can be adapted to the yarn to be treated. The twisted yarn in the twisting spindle 2 is supplied to a first yarn guide 4 of a feeding device 5 driven by a drive 6 , which draws the yarn out of th...

Abstract

The method involves detecting the tensile force acting on a twisted thread removed from a twisting spindle (2), and comparing the tensile force with a preset reference tensile force. The difference between the detected and reference tensile forces is determined as a correction factor of the driving force of a bobbin drive device (15). The driving force of the drive device and the shifting speed of a traversing device (9) are adjusted corresponding to each other, so that the windings of the twisted thread are arranged within a thread layer parallel to each other over a cross-wound bobbin (10). An independent claim is also included for a double wire twisting machine comprising a twisting spindle.

Description

technical field [0001] The invention relates to a method for precision winding of cross bobbins on a two-for-one twisting machine with several twisting stations, wherein the yarn is drawn from a feed bobbin on a twisting spindle through a traversing device Twisting and winding with bobbin driving means to form cross bobbins, the traversing means are activated according to the bobbin driving means. The invention also relates to a two-for-one twisting machine for carrying out the method, the two-for-one twisting machine having a plurality of twisting stations with a twisting spindle, a traversing device and a bobbin drive on each twisting station A device on which a feed bobbin is arranged on the twisting spindle, from which the yarn is drawn and twisted, and the traversing device is used to move the yarn on the tube to form a cross bobbin. Background technique [0002] A method of this type is disclosed in German published application with publication number DE1685978A1. It...
