Abstract
An apparatus for producing a multifilament yarn from a thermoplastic polymer includes a yarn guiding element being movable in a vertical direction. A drive serves to change the vertical position of the yarn guiding element with respect to a point of consolidation of the filaments. At least one sensor senses the yarn tension of the filaments. A control unit serves to control the drive in response to the sensed yarn tension to change the vertical position of the yarn guiding element.
Claims16
An apparatus for producing a multifilament yarn from a thermoplastic polymer, comprising:
- an injector plate being designed and arranged to produce filaments from a thermoplastic polymer;
- at least one yarn guiding element, said at least one yarn guiding element being designed and arranged to be movable in a vertical direction;
- a drive being designed and arranged to change the vertical position of said at least one yarn guiding element with respect to a point of consolidation of the filaments;
- at least one sensor being designed and arranged to sense and determine the yarn tension of the filaments;
- a control unit being designed and arranged to control said drive in response to the sensed yarn tension to change the vertical position of said at least one yarn guiding element;
- and
- a unit for winding the multifilament yarn.
An apparatus for producing multifilament yarn from a thermoplastic polymer, comprising:
- a unit being designed and arranged to produce at least partly fluid filaments from a thermoplastic polymer;
- a cooling unit being designed and arranged to cool the at least partly fluid filaments to at least partly harden at a point of consolidation;
- at least one yarn guiding element being designed and arranged to be movable in a vertical direction;
- a drive being designed and arranged to change the vertical position of said at least one yarn guiding element with respect to the point of consolidation of the filaments;
- at least one sensor being designed and arranged to sense and determine the yarn tension of the filaments;
- and
- a control unit being designed and arranged to control said drive in response to the sensed yarn tension to change the vertical position of said at least one yarn guiding element.
