• the device can not be put out of action by fluff or other impurities and consists solely of an elongated or wire-shaped element, which is transverse to the barrel of the boat and laterally displaced by this, if the thread supply and thread tension is correct. It is easy with this device
• Thread breakage or when the thread is empty or empty
• the device can be produced inexpensively, since the pin for controlling the device only an electrical connection, that is a fine wire, must be provided. To make the device even more cost-effective, it is also possible to combine a plurality of pins, for example in a module of several embroidery sites and a
