Abstract

PURPOSE: To manufacture a bent pipe having correct thickness and internal diameter by forming a molding matter layer round an elastic cylinder which is held in a straight line form and bending the molding matter together with the elastic cylinder.
CONSTITUTION: By supplying molding matter such as resin mortar between an elastic cylinder 1 which is held in a straight line form by a straight axle 2 and rotated in the circumferential directioln and a holding roll 3 is formed a molding matter large 4 round the elastic cylinder. The molding matter layer 4 is heated to some extent and hardened, then the straight axle 2 is removed from the elastic cylinder 1. As the molding matter layer 4 which is not yet hardened circles the outer circumference of the elastic cylinder 1, a curued axle is inserted into a through hole 11 of the elastic cylinder 1, the molding matter layer 4 is bent together with the elastic cylinder 1, and immediately heated and hardened. Thereafter the curved axle 5 is removed from the through hole 11 of the elastic cylinder 1 and then the elastic cylinder 1 is taken out of the the molding matter layer 4 and thereby the bent pipe is manufactured.
