Abstract

PURPOSE: To smooth and finish the inner surface of a socket with ease and good accuracy, by molding a tube from a resin material having a curing rate lower than the other part used forming the socket inner surface only.
CONSTITUTION: The band material 6 impregnated with a resin containing a hardener which will decompose at a relatively high temperature, etc. is wrapped around the the mandrel 1 and the inner layer 5 of the socket to form the inner surface layer. A filler is fed from the filler feeder 7 to the surface of the material 6 to form the intermediate layer. The band material 9 containing a hardener which will decompose at a relatively low temperature, etc. is wrapped around the intermediate layer to form the outer layer. The tubular material thus obtained is passed through the heating furnace 10 and cured without curing the inner surface 5 of the socket sufficiently. The semicured inner layer 5 is then cured after processing into a desired state.
