Abstract

PURPOSE: To prepare uniform curved tubes by winding a shaping core material consisting of a wire and a molding material around a core bar and curving and thermosetting these two materials after removing the core bar.
CONSTITUTION: A molding material layer 3 is formed by winding a separable film on a core bar 1, a wire 2 spirally on the film at proper intervals and further a molding material 3' comprising a strip made of glass fiber or the like and a resin such as unsaturated polyesthel impregnated in the strip. The molding material layer 3 thus formed on the core bar 1 is made to pass through a heating furnace 4 so as to increase the viscosity of the resin to such an extent that the resin is not thermoset, and then cut into a plurality of tube pieces having a predetermined length. The core bar 1 is drawn out of each tube piece and thereby a hollow tube including wire in its molding material layer 3 is obtained. A processing core bar 7 is inserted into the hollow tube for curving the tube to a predetermined angle and a thermosetting process is applied thereto. Thus a curved tube can be obtained.
