Definitions

  • the invention relates to a thread processing system according to the preamble of claim 1 and a method according to the preamble of claim 47.
  • a feeder unit carrying the thread supply in order to change or adjust the draw length.
  • the unit can be formed by finger-shaped elements which are seated on radial arms and can be adjusted individually or together.
  • different thread qualities need different winding distances in order to ensure an optimal feed to the textile machine.
  • a stop function is provided which limits the withdrawal length of the thread. Especially with such foumisseurs, there is a need for automated operation when changing the size of the unit.
  • the change in circumference should be integrated and take place during operation, ie during weaving.
  • the setting should work with feedback functions and very precisely.
  • the change in circumference should take place with retained thread separation or with a thread separation dependent on the setting, because the thread separation ensures precise and effective control of the Thread supply on the unit is made possible, which otherwise has to suffer from the change in circumference and can cause malfunctions.
  • the invention solves i.a. this problem, which is not possible with currently known solutions, and that because of technically less well functioning and less accurate working systems that make the initial change while ignoring the condition or the harmful influences in the thread supply on the unit.
  • a stop element defines the draw-off length and the thread stretch for the weft thread insertion into the weaving machine. If the size of the unit changes, the stop element must be readjusted. It has therefore been proposed to give the stop member a fixed position in the room and to adjust the unit eccentrically. This requires a transverse displacement of the longitudinal axis of the unit relative to the longitudinal axis of the supplier or an asymmetrically changed cross-sectional volume of the unit and complicates the structure of the supplier. Above all, this principle leads to uneven winding tensions, which take effect along the turns, which means unfavorable effects on the weaving result.
  • the thread separating function is such that it can be controlled individually in connection with the size or in connection therewith. Like the change in scope, it can be carried out in a sub-process by means of a or several processes taking place before or in the function of the textile machine, for example when weaving.
  • the present invention also solves this problem and proposes an arrangement that, from the web or economic point of view, delivers optimal print lengths.

  • the feeder will release the required amount of thread.
  • control equipment is capable of generating one or more control signals which affect the setting element and which result from the start of the textile machine function / weaving function, from the thread change, from a change in media pressure in the nozzle function, etc.

  • the unit is provided with a thread separation function, which is present or can be introduced in preferably all possible circumferential sizes for the unit.
  • the thread separation function is of primary importance in the case of a change in diameter, because the distances between the turns in the thread supply ensure that the thread supply is constantly checked or that a compensation option is created to limit the effective tension increase in the thread supply to a harmless level or increase the diameter. if the diameter is reduced over the distances, ensure that the turns do not get over or under each other and become confused. In both cases, breaking the thread would lead to a malfunction resulting from the change in diameter. In known systems, the change in diameter during operation is directed the influences on the thread supply are ignored.
  • the thread separation which is maintained according to the invention when the diameter changes during operation or is even individually controlled, creates a regulative in the thread supply, which compensates for influences resulting from the change in diameter and avoids malfunctions.
