Workstation of an air-spinning machine, and thread-guiding element

Abstract

The invention relates to a thread-guiding element and to a workstation of an air-spinning machine, the workstation comprising an air-spinning device for spinning a thread from a supplied sliver, a thread-guiding unit, which is downstream of the air-spinning device and has an inlet opening for receiving the thread exiting from the outlet opening of the air-spinning device and a thread guide channel for conducting at least the air-spun thread coming from the air-spinning device, and a thread-guiding element for arranging between the outlet opening of the air-spinning device and the inlet opening of the thread-guiding unit. In order to provide a workstation of an air-spinning machine and a thread-guiding element for use at a workstation of a spinning machine, more particularly an air-spinning machine, which ensure that a thread end is reliably returned to the spinning device, it is provided that the thread-guiding element a channel body having a through-channel, which channel body has: a connection section, which is designed for connection to the spinning device and is provided for arranging a first open end of the through-channel in the area of the outlet opening of the spinning device; and an end section, which can be arranged facing the inlet opening, wherein the end section, in order to receive a thread exiting from the inlet opening, is matched to a contour of the thread-guiding unit surrounding the inlet opening.

What is claimed is: 
     
         1 . A thread-guiding element for arranging between an outlet opening of a spinning device and an inlet opening of a thread-guiding unit having a thread guide channel for conducting a thread through the thread-guiding unit,
 characterised by   a channel body having a through-channel, which channel body has
 a connection section, which is designed for connection to the spinning device and is provided for arranging a first open end of the through-channel in the area of the outlet opening of the spinning device, and 
 an end section, which can be arranged facing the inlet opening, 
   wherein the end section, in order to receive a thread exiting from the inlet opening, is matched to a contour of the thread-guiding unit surrounding the inlet opening.   
     
     
         2 . The thread-guiding element according to  claim 1 , characterised in that the thread-guiding unit has a thread deflection unit for deflecting the thread in a defined way, which thread deflection unit forms the inlet opening and comprises, at its end opposite the inlet opening, an exit, which is coupled to the inlet opening by a thread deflection section lying therebetween and by which the thread deflection unit can be connected to the thread guide channel for conducting the thread through the thread-guiding unit to the inlet opening. 
     
     
         3 . The thread-guiding element according to  claim 2 , characterised in that the end section is matched to the contour of the thread deflection unit in the area of the inlet opening. 
     
     
         4 . The thread-guiding element according to  claim 1 , characterised in that the connection section is designed for bayonet-coupling-type connection to the spinning device. 
     
     
         5 . The thread-guiding element according to  claim 1 , characterised in that the channel body is made of a plastic material. 
     
     
         6 . The thread-guiding element according to  claim 1 , characterised in that the end section is funnel-shaped. 
     
     
         7 . The thread-guiding element according to  claim 1 , characterised in that the channel body has a plurality of air passages along the through-channel, for causing a rotational flow within the through-channel. 
     
     
         8 . The thread-guiding element according to  claim 3 , characterised in that the end section is matched to the contour of a deflection roller of the thread deflection unit. 
     
     
         9 . The thread-guiding element according to  claim 5 , characterised in that the plastic material is PVC. 
     
     
         10 . A workstation of an air-spinning machine, comprising
 an air-spinning device for spinning a thread from a supplied sliver and a thread-guiding unit, which is downstream of the air-spinning device and has an inlet opening for receiving the thread exiting from the outlet opening of the air-spinning device and a thread guide channel for conducting at least the air-spun thread coming from the air-spinning device,   characterised in that
 a thread-guiding element characterised by:
 a channel body having a through-channel, which channel body has a connection section, which is designed for connection to the spinning device and is provided for arranging a first open end of the through-channel in the area of the outlet opening of the spinning device, and 
 an end section, which can be arranged facing the inlet opening, 
 
   wherein the end section, in order to receive a thread exiting from the inlet opening, is matched to a contour of the thread-guiding unit surrounding the inlet opening,   is arranged in the area between the outlet opening of the air-spinning device and the inlet opening of the thread-guiding unit.
