Patent ID: 7594382

Claim:
Joining method on a spinning device of a jet spinning machine ( 1 ), wherein a fibre band ( 14 ) drawn to yarn thickness is supplied by a drawing frame ( 4 ) to the spinning device ( 5 ), between an input-side mechanical twist retaining mechanism ( 54 ) and a spinning cone ( 25 ), a rotational flow is produced by a spinning nozzle mechanism, which collects fibres forming free fibre ends and winds them producing a true twist around fibres which do not take part in the rotation and are already incorporated, and the thread ( 26 ) thus formed from the fibre band ( 14 ) is drawn through the hollow spinning cone ( 25 ), wherein, for joining, an auxiliary thread ( 30 ) is used, which is firstly threaded by its free end into the spinning device ( 5 ) and drawn through the spinning cone ( 25 ), wherein joining then takes place on the continuous auxiliary thread ( 30 ) not taking part in the torsion, in that the fibres of the fibre band ( 14 ) are fed onto the auxiliary thread ( 30 ) and wound around it, and wherein the auxiliary thread ( 30 ) being subjected to the withdrawal is guided off and after passing the auxiliary thread end, the newly spun thread ( 26 ), which is free of auxiliary thread, is separated and connected to the end of the upper thread ( 38 ) by a knot or a splice.
