摘要:
A system for forming twisted pultruded fiber reinforced rods is disclosed. In the system of the invention fibers are coated with a resin, drawn through a shaping die and then after at least partially curing, the rod is simultaneously twisted and pulled through the coater by opposed pulling surfaces that rotate as they pull to twist said rod.
