摘要：A composite reinforcing bar is formed by providing a reinforcing material supply of fiber strands rovings; a resin supply bath, and a puller for pulling the resin-impregnated reinforcing material through the resin bath. The material is wound on a holder, while the resin remains unset, rotated about its axis on a drive system so that the material is wrapped around a plurality of bars at spaced positions around the axis such that the fed length of the body is wrapped from one bar to the next to form bent portions of the body wrapped partly around each bar and straight portions between the bars. Each bar has angularly grooves which are shaped to mold the bent portions to a required bent shape. The holder is indexed along it axis and removed when full for curing the resin on the holder while the body remains wrapped thereon.
