Definitions

  • the present invention relates to a thread deflection unit for a textile machine, the thread deflection unit having a housing which comprises a curved wall section for forming a radially outer wall section of a curved thread deflection channel.
  • Thread deflection units for deflecting a running thread are well known in many designs in the field of textile machines. Such a thread deflection unit usually interacts with a thread deflection roller, via which the thread is deflected from a first direction, from which the thread hits the thread deflection roller, in a second direction deviating from the first direction, in which the thread leaves the thread deflection roller.
  • a thread deflection unit is, for example, from the subsequently published publication DE 10 2017 115 939 A1 known.
  • Usual thread deflection rollers for textile machines are also examples from the publication DE 10 2009 021 066 A1 known.
  • a problem with previously known devices for thread deflection is that the thread deflection is only possible for a deflection angle of 90 ° or greater, which is included in the first and second direction, without adverse effects on the thread handling.
  • a plurality of thread deflection units are usually connected in series in the thread running direction, as a result of which corresponding installation space must be made available.
  • the object of the present invention is to develop the previously known thread deflection unit in such a way that, in particular, space-saving thread deflection for deflection angles of less than 90 ° is made possible, along with improved thread handling.
  • a thread deflecting unit for a textile machine which has a housing which has a curved wall section for forming a radially outer or outer wall section of a curved thread deflecting channel includes.
  • a curved or a curved course is understood to mean embodiments which deviate from a straight course along the course direction between an initial section and an end section.

  • the wall preferably has at least one air flow passage communicating with an environment of the wall, via which a defined air flow component can be exchanged between the thread deflection channel or the thread guide groove and the environment.
  • the at least one air flow passage preferably acts with a regulating device for automatic and / or manual regulation or adjustment of the air throughput exchangeable via the air flow passage.
  • An open contour of the wall thereby reduces a dynamic pressure and the associated turbulence in the thread deflecting channel and the thread guide groove, as a result of which the thread handling during thread transport can be further improved by means of air flow guidance.
  • the air passage in the course of the curved wall section which corresponds to a transport direction of the thread within the thread deflecting channel or the thread guide groove, is further preferably arranged in the wall between an inlet and an outlet of the thread guide groove and / or the thread deflecting channel, or is formed by the wall.
  • the air flow can generally be an air flow generated as a result of compressed air or suction air.
  • the compressed air in the transport direction of the thread upstream to the curved wall section or the suction air in the transport direction of the thread downstream to the curved wall section can be introduced into a channel communicating with the thread deflection channel or the thread guide groove.

  • the yarn strength can be influenced in a suitable manner or a defined yarn strength of the thread can be taken into account during the accompanying transport thereof by the air flow to be generated.
  • the thread guide groove along the curvature forms a cross-sectional shape that is open on one side, for example a V, U or W cross-sectional shape or a similar cross-sectional shape with legs that taper or converge in the direction of the open-ended end of the cross-sectional shape.
