ABSTRACT:
An improved process, and the apparatus for carrying out the process, of forming an elongated hollow body from fibre-reinforced synthetic resins. A plurality of resin impregnated support fibres are positioned over and extend longitudinally along a rotating mandrel, which support fibres are fed from a feed station having a plurality of spools thereon, which feed station rotates synchronously with the mandrel. The longitudinal support fibres form a fibrous substructure which rotates with the mandrel. A plurality of fibrous elements, also resin impregnated, are wrapped around the fibrous substructure to form the hollow body. The hollow body is gripped by a clamping device disposed at the discharge end of the rotating mandrel for pulling the hollow body and thereby displacing same longitudinally along the mandrel, which clamping structure simultaneously permits rotation of the hollow body with the mandrel.
