Zusammenfassung:	Apparatus for producing bent multi-sided pultruded fibre reinforced plastic reinforcement bar for concrete (commonly known as FRP rebar) comprises multiple resin wetting stages to simultaneously resin impregnate multiple bundles of fibreglass rovings continuously drawn through the resin wetting stages, multiple spiral winding stages arranged to spiral wind warps around the multiple wet rovings, and multiple rotating multi-sided former frames for continuously winding thereon the multiple wet rovings and holding the multiple rovings while curing. A related method is also claimed.
