ABSTRACT:
A spool winding assembly for winding a composite strip onto a spool having a hub is disclosed. The strip includes an elongate plastic strip having a flat base portion and a plurality of laterally spaced apart lengthwise extending rib portions upstanding from the base portion; and a plurality of elongate reinforcing members extending lengthwise within respective rib portions, the rib portions and the reinforcing members forming composite ribs. The assembly includes: a main frame, a spool holder for rotatably supporting the spool relative to the main frame, a spool drive unit for driving the spool with respect to the main frame, a carriage mounted for lateral movement with respect to the spool, a bender mounted to the carriage for receiving the strip as it is fed towards the hub of the spool and for deforming the strip to give it a curved base portion, and a bender drive unit operably connected to the bender for driving the strip through the bender.
