Definitions

  • the invention relates to a holding device for an intermediate support of a warp stop motion of a loom.
  • the invention also relates to a support device with an intermediate support and two holding devices arranged at the two ends of the intermediate support.
  • Warp stopper for weaving machines are known per se.
  • the warp stop motion is used to detect warp yarn breaks during operation of a weaving machine, so that the weaving process can be stopped immediately and the warp thread can be replaced. This avoids fabric being made with weaving defects.
  • a warp stop motion detector has contact rails arranged transversely to the direction of extension of the warp threads.
  • contact blades are arranged, which can short-circuit two mutually insulated electrical contacts of the Kotaktschiene when the associated warp thread breaks.
  • Below the contact rail of the associated warp thread passes through a hole in the contact blade. If the warp thread breaks, the contact lamella falls down and briefly closes the two contacts of the contact rail. This short circuit is detected, so that a Kettfadenbruch can be detected immediately.
  • the contact rails extend in a longitudinal direction transverse to the warp direction. They are connected at their longitudinal ends with the frame of the loom, as for example in EP 1 598 462 B1 is explained.
  • damping means may be interposed in the region of attachment of the contact rails with the machine frame of the loom.
  • For long contact rails it is necessary to additionally support them in the area between their two longitudinal ends.
  • the intermediate support extends between two thread carrying tubes of the warp stop motion, which extend in the longitudinal direction parallel to the contact rails.
  • Such a support device with an intermediate support is in EP 1 598 462 B1 only very schematically illustrated.
  • the support means includes a holding device to secure the intermediate support on the thread support tube.
  • a holding device is, for example, from the technical information Weaving 7 "Kettfadenwumbleter in overview", EN 08.2011 the applicant known.
  • the holding device has a support part and a clamping part, which serve for fastening the support means with the intermediate support on a thread support tube, as is schematically illustrated, for example, on page 2 of this publication below.
  • the support member comprises the thread support tube from below, while the clamping part on the side facing away from the intermediate support at the beginning of the curvature of the thread support tube is laterally stretched.
  • the clamping parts are located below a plane that is applied tangentially to the upper radii of the two thread carrying tubes of the warp straightener.
  • an object of the present invention is to provide a support means for an intermediate support of a warp stop motion and a support means with intermediate support and two holding devices whose life is increased.
  • the holding device for an intermediate support has a supporting part and a clamping part which can be fastened to the supporting part.
  • the support member and the clamping member are adapted to be attached to the thread support tube of Kettfadenissechters.
  • On the clamping part is a first holding surface and the support member is a second holding surface available.
  • the two retaining surfaces adjoin a recess which is formed by the support member and the clamping part.
  • the limited by the clamping part and the support member recess in the circumferential direction is closed completely or at least in an angular range about the longitudinal axis of the thread support tube of at least 270 ° or 300 °.
  • the first holding surface and the second holding surface are in each case flat against the thread carrying tube, when the holding device is fastened to the thread carrying tube and / or the first holding surface and the second holding surface abut at a position on the thread carrying tube, which extends on the side of the longitudinal center plane through the Thread carrying tube is located, on which also supported by the holding device intermediate support is arranged.
  • the longitudinal center plane through the thread carrying tube is oriented at right angles to a transverse direction.
  • the transverse direction is the direction in which the intermediate support extends.
  • a relative movement of the holding device relative to the thread carrying tube is reduced by one or both measures, which can be triggered by vibration or vibration during operation of the loom.
  • Such relative movements can lead to the fact that the fixation of the holding device loosens or loosens on the thread carrying tube, whereby the movement play of the holding device relative to the thread carrying tube increases.
  • the loads on the holding device increase and can lead to breakage of the holding device.
  • the holding device according to the invention is better fixed by the flat contact of the two support surfaces and / or, so to speak, by the overlapping of the thread support tube with respect to previous holding devices on the thread support tube.
  • the holding device can be held free of play on the thread carrying tube and / or positively, so that no increased play between the holding device and the thread carrying tube is formed by vibrations during operation of the loom.
  • the holding device surrounds the thread carrying tube such that a positive fastening is achieved in all directions transversely to the longitudinal direction of the thread carrying tube. The loads on the holding device during operation of the loom do not increase. The life of the holding device and thus the support means with the intermediate support is increased.

  • the first holding surface and / or the second holding surface thus abuts against a curved section of the thread carrying tube in the circumferential direction and in the longitudinal direction, so that an uninterrupted planar contact between the respective holding surface and the thread carrying tube can be produced.
  • a positive encompassing of the respective associated peripheral portion of the thread carrying tubes is independent of the force with which the clamping member or the support member is pressed against the thread support tube.
  • the curved portion of the first holding surface and / or the second holding surface is preferably in an angular range of at least 90 ° or at least 120 ° on the thread support tube.

  • the clamping part and the support member In the clamping position of the clamping element, the clamping part and the support member are non-positively and preferably positively clamped against the thread support tube. The pivotability of the clamping member in the release position of the clamping element simplifies the mounting of the holding device on the thread support tube.
  • the pivot axis may preferably extend inclined relative to the longitudinal center plane through the thread support tube and thus cause a force component in the longitudinal center plane and a force component transverse to the longitudinal center plane between the holding device and the thread support tube.

  • the intermediate support or the spacer element may abut against a support surface of the support projection, so that over the support projection, a transverse force in the transverse direction parallel to the extension direction of the intermediate support can be added to the holding device.
  • the support surface of the support projection rests against the intermediate support or the spacer element in particular when the tensioning element is in its clamping position.
  • this or the spacer element mounted thereon can be supported between the two holding devices and in particular between the two support projections in the transverse direction at both ends or acted upon by a clamping force.

  • the two sections of the first holding surface adjoin one another in the circumferential direction.
