Method for removing and drawing a synthetic thread and a device for performing the method

摘要

The invention relates to a method and a device for removing and drawing a synthetic thread to form a fully drawn yarn. The thread is formed by joining a plurality of extruded filaments and is guided by contact on the circumference of heated guide jackets of several driven galette pairs. In order to obtain a gentle and highly homogenized treatment of the filaments, the thread is guided in an S-shaped or Z-shaped thread course by a first galette pair having two guide jackets driven in opposite directions during the removal from a spinning zone and before the drawing. Thus, both sides of the thread can be brought directly into circumferential contact with the guide jackets for in order to heat the thread.

1. A method for removing and drawing a synthetic thread to form a fully drawn yarn (FDY), said method comprising:
foaming the thread by joining a plurality of extruded filaments; and guiding the thread by contact on the circumference of heated guide jackets of first and a second driven galette pairs, wherein the thread is guided in an S-shaped or Z-shaped thread course through the first galette pair having two guide jackets driven in opposite directions during the removal from a spinning zone and before the drawing and wherein the thread is guided in an S-shaped or Z-shaped thread course through the second galette pair having two guide jackets driven in opposite directions after the drawing procedure, wherein the thread is fully drawn in a drawing zone formed allied between the first and the second galette pairs.
