  • the invention further relates to a circular loom, to which a plurality of warp tapes can be fed to a Rundriet, with a main drive and a control device, wherein the circular loom is equipped with Kettbändchenwumbletern.
  • Round looms of this type are for example from the document EP 0 786 026 B1 known.

  • the warp tapes of each reel are fed individually to the round reed of the circular loom.
  • a warp or warp winding is exhausted, ie If the warp tape on it has reached its end, the empty warp spool concerned must be replaced by a full spool (or the entire warp beam) and the new warp tape (s) must be threaded into the circular weaving machine.
  • warp tape guards have been developed that can detect the exhaustion of a warp coil and give a warning signal.
  • Such a Kettbändchenwumbleter is eg from the document DE 562975 known.
  • Kettbmixchenende is accelerated as a rubber band before by the sudden weakening tension when a warp spool exhaustion, whereby it usually gets into a position in which it is not tangible for the attachment of the replacement Kettbmixchens.

  • the control device shuts off the main drive when a quiescent signal occurs.
  • the passage for the Kettbändchen in the sensor piece is formed transversely to the direction of its reciprocating motion between the rest position and the working position.
  • a short and consequently low-friction path of the warp strip is created through the sensor piece.
  • the occurrence of deflection forces on the sensor piece is prevented obliquely to the direction of displacement.
  • changes in the tension of the warp tape and its associated more or less severe sagging to considerable displacements of the sensor piece which are of course easier to detect than minor displacements.
  • the passage for the warp strip in the sensor piece is formed as a laterally open groove, whereby a great deal of time is saved when hooking the Kettbmixchens when commissioning the circular loom.
  • the sensor piece is mounted rotationally fixed.
  • the clamping device is provided with a clamping surface designed as a friction surface, wherein preferably the friction surface is provided by a friction lining, such as e.g. a gumming, or surface roughening, or the formation of serrations is realized.

  • a sensor piece is cheap and accurate to produce, with the clamping forces occurring between the sensor piece and the clamping device are well-defined.
  • the shaft is guided axially displaceable.
  • the axial mobility of the shaft defines the reciprocating direction of the sensor piece between the rest position and the working position as a translational movement. This translatory movement is easily detectable by the detector, which is why it is preferred in this embodiment that the detector detects the approach of the sensor piece to its rest position on the basis of the position of the shaft.
