ABSTRACT:
An apparatus to recover and restring a broken threadline in a processing multiple running threadlines includes a waste suction device to collect the broken threadline, an interlacing jet to splice the broken threadline onto a running threadline, a forwarding jet to maintain tension on the broken end, a coanda surface at the exit end of the forwarding jet to deflect the broken end into the suction device. While the broken end travels over a notched swing pin to the waste suction device the swing pin is moved to contact the running end which is pulling the broken end spliced to it forward. The action of the swing pin and a pin or cutter blade at the exit of the forwarding jet serves to sever the filaments of the tensioned broken-end threadline which results in a double end running to a sucker gun at the windup. The ends are then separated, placed in the proper guides and restrung.
