A winding machine, such as a UNIFIL loom winder, manufactured by Leesona Corporation, Warwick Rhode Island 02887, has a spindle assembly for receiving and rotating a bobbin, and a traversing assembly including a traversing member having a pair of jaws releasably threadedly secured to a traverse rod, during winding, for guiding a strand of yarn being wound onto the bobbin. The traversing and spindle assemblies are driven by mechanism within a casing of the winder. This mechanism includes a continuously driven drive shaft connected by a clutch with a spindle shaft which rotates the bobbin and rotatably receives cams for operating the threaded traverse rod to provide the traversing member with builder and reciprocating motions. When the clutch is drivingly engaged it supports an end of the spindle shaft, and when the clutch is disengaged this end of the spindle shaft is supported on a unit which journals the shaft for axial movement. At the end of winding of a bobbin, bobbin doffing and donning operations are initiated, the clutch between the drive shaft and the spindle shaft is released, the jaws are released from the traverse rod and the traversing member is returned to its starting point, the yarn is cut between the traversing member and the doffed, filled bobbin, and the cut yarn is engaged for winding onto an empty bobbin previously donned into the winder. When the traversing member has been returned to its starting position, the clutch again drivingly engages the drive shaft and spindle shaft whereupon the cycle is repeated.
