Abstract
The shuttle of the tying device is of magnetic metal, at least at its extremities. Each extremity of two arms is fitted with an electromagnet for temporarily receiving and retaining the corresponding extremity of the shuttle. The electromagnets are energized in alternate sequence through circuits comprising switches which are actuated in synchronism with the forward and backward movements of the arms by means of stationary contact-studs.
