Method and device for producing a crimped multifilament thread |
摘要 |
A method and a device for producing a crimped multifilament thread are described. A multiplicity of filaments are extruded by means of a spinning machine, cooled and subsequently treated by a drawing device and a crimping device to form a crimped thread. Before the thread is wound up to form a bobbin, a multiplicity of intertwining knots is produced on the crimped thread by a treatment device. In order to obtain defined patterns of the intertwining knots within the thread, a pulse sequence of compressed air pulses at a predefined frequency is directed at the thread. The treatment device has a controllable blowing means. |

1. A device for manufacturing a crimped multifilament thread comprising:
a spinning apparatus; a stretching apparatus downstream of the spinning apparatus; a crimping apparatus downstream of the spinning apparatus; a treatment apparatus downstream of the spinning apparatus for producing an intertwined knot, wherein the treatment apparatus is arranged in a thread track between two driven godets; the treatment apparatus including a controllable blowing apparatus that has a rotationally driven nozzle ring with a peripheral thread guide track and at lease one nozzle bore opening into the thread guide track, which is periodically connected with a compressed air source by rotation of the nozzle ring for periodically producing a compressed air pulse directed on the thread; an enclosure having a thread inlet and a thread outlet with the enclosure being arranged at a front side of a support wall and completely surrounding the nozzle ring to enclose the nozzle ring; and an electric motor associated with the nozzle ring, wherein a back side of the support wall supports the motor. |
