Abstract
The invention relates to a process and apparatus for manufacturing a body to be reinforced with a fiber-composite material, especially bottles or containers or metal or plastic for holding a pressurized gaseous medium, in which a plurality of light, high-strength inorganic or organic, non-conductive or conductive as well as non-metallic yarns are wrapped around the body, whereby individual fiber strands or fibers are unwound and are bundled and, prior to being wound on the body, are impregnated with a plastic material. The wrapping of the yarns is carried out with controllable, pre-tensioned yarns. During wrapping, the individual yarns are again impregnated with a polymer melt of thermoplastic and each individual wrapping layer is smoothed and/or cooled by a temperature-controlled roller.
