ABSTRACT:
Prior to doffing a bobbin package, the roving is severed to form a beard which is located adjacent a stop on the spindle. After the bobbin package is doffed, the beard is located adjacent to an axial stop on the spindle. When a fresh tube is donned, the roving beard is brushed down by the tube and clamped by the bottom of the tube against the axial stop. A new package can then be wound while the roving beard remains clamped.
