ABSTRACT:
A material winding and cutting machine is capable of automatically winding and cutting specified lengths of a material formed on a removable workpiece. Winding spindles (10 and 11) are rotatably mounted to drum (4) and revolve with the rotation of the drum between a winding station and a doffing station. Tubes (20) and fixed to the spindles (10 and 11) to receive the material (13). The machine includes a brake (27) which stops rotation of the material (13) about a winding spindle (10) during the cutting operation. The brake assembly stops the winding spindle to provide for an accurate cutting of the material to a predetermined length. Since the material does not rotate about the winding spindle during the cutting operation, the winding spindle incorporates a force storage device (28) to provide the needed tension to the material for proper cutting.
