For this purpose, the completion of the preparation can be notified by pressing a button or a button of the control device.

This, in turn, offers advantages, as otherwise, for example, could possibly fall through falling or hanging objects such as the free tail in the range of action of the transmitter and so unjustifiably trigger a stop the winder.
  • FIG. 2 shows the winding shaft 102, which is already equipped with a new, empty winding tube 105.

  • the winding 123 is here in a position in which he by the operator from the Winding device can be removed. However, this winding 123 covers the sensor 121 shown in FIG. 1. This means that this sensor detects the presence of a coil and signals this to the control device. With the control device, the transmitter 116 is now deactivated or the deactivation maintained as long as the winding is in the detection region of the coil 123. Only when the winding has been removed, this is detected by the sensor 121, so that the transmitter 116 is activated. Since this is done automatically, ie without any control by the operator, the transmitter .116 is active when the operator loads the winding shaft with a new, empty winding tube 106.
