Definitions

  • the invention relates to a method and an apparatus for continuously withdrawing a thread from a supply spool, as well as a method and a texturing machine for texturing a synthetic multifilament thread
  • the method and the device for pulling off a thread are known and are used in textile machines in which a thread placed in front is worked or processed.
  • the thread is drawn off continuously from a supply spool and fed to the subsequent process.
  • the thread end is the supply spool is knotted with the start of the thread of a second supply spool, which is referred to here as the reserve spool, after the supply spool has expired there is an automatic overflow to the reserve spool, the end of the thread in turn being knotted at a thread start of another spool, so that the process runs continuously the knot-like bindings during the subsequent processing or processing of the thread represent problem areas which can lead to defects in the finished product. In extreme cases, the binding can become loose, so that a thread breakage occurs
  • a crimped thread is produced from a plain thread.
  • the thread is twisted and thermally treated for fixing in the twisted state between a thread end of a supply spool and a thread start of a second supply spool (reserve spool) Twist distribution, which results in an uneven crimp.
  • Such imperfections can lead to color defects, for example, in the further processing of the crimped yarn
  • Another object of the invention is to provide a method and a texturing machine for texturing a synthetic thread in order to produce certain packages with crimped yarn which can be assigned to the supply spool and are made from predetermined supply spools with a smooth yarn

This indicates, for example, to an operator that a change in the yarn being prepared is imminent in the machining or processing process. This provides an association between the finished or end product and the supply spool The operator can take measures to avoid possible fault events due to the knot-like binding in the thread.

  • a particularly simple and effective embodiment of the invention is given by the method variant according to claim 4. Since the thread end of the supply spool and the thread start of the reserve spool stand still during the withdrawal of the supply spool, the movement of a piece of thread in the area can already be used to signal the yarn change
  • This variant of the method is characterized in particular by the fact that simple device parts are required for implementation.

  • a textured smooth yarn is textured and then wound as a crimped yarn on a spool.
  • several end spools are wound with crimped yarn from a supply spool. It is necessary for the spool to be changed in the winding discharged as waste in a suction device. It is now due to the method variant according to the invention possible to initiate a bobbin change in the reel in such machines.
