Abstract
1,073,978. Moulding hollow tubular articles. SACHSISCHE GLASFASER-INDUSTRIE WAGNER & CO. KOMM. GES. Sept. 11, 1964, No. 37193/64. Heading B5A. [Also in Division F2] A method of producing an elongated elastically resilient hollow body e.g. a vaulting bale, comprises forming a resin impregnated blank of fabric contoured in accordance with the distribution of stress along the length of the body, wrapping the blank round the prepared surface of a core to form a plastics tube of varying wall thickness, setting the plastics material and removing the core. The core surface may be prepared by coating with a parting medium e.g. wax which expands on melting so as to apply outward pressure on the fabric. An electrically conducting foil wound round the fabric may be used for heating the impregnated resin e.g. a polyester, epoxy or phenolic resin or a conducting core may be used.
