Abstract

Two bobbin tubes are mounted on a common bobbin chuck and a common thread severing means and suction means is used to sever and hold the threads during a bobbin change. After the threads are severed and drawn into the suction tube, a rod which carries two thread holders and the suction tube are pivoted into the thread path and around the fresh empty bobbin tubes on the chuck. A second pair of thread holders guide the threads during this time. After re-threading on the bobbin tubes, the rod and suction tube are returned to their initial positions to place the threads into respective reserve winding devices and thread guides.
