Abstract

Elbow from glass fibre reinforced thermosetting synthetic resin is produced byh winding continuous glass filament on to a mandrel which previously or subsequently are impregnated with a resin, and hardening the assembly. The glass filament are wound on the an elastically mouldable mandrel. Specifically, the mandrel is an expanding elastic casting which is filled with a hydraulic medium and which is removed from the casing after moulding and hardening after letting out the hydraulic medium.
