  • An exchangeable capsule is arranged on the shuttle and contains a weft bobbin with the weft thread inside. These boats can be loaded with full spools.
  • the EP 2 570 530 A1 describes a warp tape monitor for weaving machines, with a sensor piece that has a passage for a warp tape, the sensor piece between a rest position, into which it is pretensioned, and a working position, into which it can be displaced by a tensile stress of the warp tape passing through the passage, is floating.
  • the CH 199413 A discloses a weft bobbin changing device for different types of looms with a fixed bobbin storage container.

  • the hammer can be actuated via a bumper, for example by an eccentric cam, so that the expired coil is replaced by the new one Coil is displaced.
  • the known circular looms have the disadvantage that the replacement of used weft bobbins is laborious. So far, the circular loom has to be stopped for this. Then the weft coils are exchanged manually. When handling the weft bobbins, special care is required to avoid damaging the weft bobbins, the fabric, and possibly even the circular loom.
  • the object of the present invention is to eliminate or at least alleviate the disadvantages of the prior art. Accordingly, the invention aims in particular to simplify the handling of the weft bobbins and to reduce the downtimes of the circular loom.

  • the gripper elements are preferably arranged at a distance from one another which corresponds to the distance between the contact points of the gripper elements on the weft spool. If the bobbin holder is set up to hold the longitudinal axis of the weft bobbin essentially in a tangential direction with respect to the main axis of the circular loom, the gripper elements are preferably spaced apart from one another in a tangential direction.
