Thread inserter and braking mechanism for a knotting apparatus used on spooling machines

摘要

A thread inserter and braking mechanism for a knotting apparatus used on spooling machines includes thread inserting and braking arms disposed on either side of the binding heads and external to the housing mounting the knotting apparatus. Brake pads disposed on either side of the housing cooperate with the thread inserter and braking arms and interact with the threads, retaining the threads to be knotted therebetween. The braking action overcomes the pressure exerted against the threads by the lifting arms of the knotting apparatus and retains the threads in position until the threads are released from the binding heads and a tight knot is formed therein.
