Method for arranging a fibre strand on a spinning device of a spinning station

Abstract

A method for arranging a fibre strand on a spinning device of a spinning station, wherein the spinning device is fed the fibre strand in order to produce a spun thread from the fibre strand by means of a drafting unit having a plurality of roller pairs. The roller pairs of the closed drafting unit are each operated, in a manner corresponding to the predefined drafting ratio of the fibre strand, with an introduction speed lower than the operating speed of the drafting unit, the fibre strand is subsequently introduced into the clamping region of an input roller pair of the drafting unit and the drafted fibre strand, after passing through the closed drafting unit and exiting a clamping region of an output roller part of the drafting unit, is subsequently fed to the spinning device.

1 . A method for arranging a fibre strand at a spinning device of a spinning station, wherein the fibre strand is fed, by a drafting system having several roller pairs, to the spinning device for the manufacture of a spun thread from the fibre strand,
 characterised in that
 the roller pairs of the closed drafting system, are each operated, in accordance with the predefined draft ratio of the fibre strand, at an insertion speed which is lower than the operating speed of the drafting system, 
 the fibre strand is then inserted into the clamping area of an input roller pair of the drafting system and 
 the drafted fibre strand is then fed to the spinning device after passing through the closed drafting system and exiting a clamping area of an output roller pair of the drafting system. 
   
     
     
         2 . The method according to  claim 1 , characterised in that the fibre strand, after passing through the drafting system, is fed to a spinning device designed as an air-jet spinning device. 
     
     
         3 . The method according to  claim 1 , characterised in that a suction air flow generating device of the air-jet spinning device is activated before or during the arrangement of the fibre strand at the air-jet spinning device. 
     
     
         4 . The method according to  claim 1 , characterised in that the air-jet spinning device is opened before or during the arrangement of the fibre strand at the air-jet spinning device. 
     
     
         5 . The method according to  claim 4 , characterised in that, after the fibre strand has been transferred to the air-jet spinning device, the drafting system is stopped, the air-jet spinning device is closed and the suction air flow generating device is deactivated. 
     
     
         6 . The method according to  claim 1 , wherein the roller pairs are individually drivable.
