发明名称 MOLDING METHOD FOR BENT PIPE MADE OF RESIN
摘要 PURPOSE:To contrive an improvement in productivity and stabilization in quality by preventing a useless reciprocating movement of a roving, by so constituting the title method that a winding surface of the roving crosses always at right angles with an axial tangent line of a core metal at a winding position. CONSTITUTION:As for a core metal 1 of a bent pipe, an end part in a longitudinal direction is fitted turnably on an end part of a shaft 3 through a connecting part 2. A turning range of the core metal 1 of the bent pipe is set up to the extent of its corner. The other end part in a longitudinal direction of the core metal 1 of the bent pipe is fitted turnably to an end part of an expansion and contraction shaft 6 by a connection part 5 and the other end part of the expansion and contraction shaft 6 is fitted turnably to a shaft 8 by a connection part 7. A roving 17 is so constituted that it is wound round the core metal 1 of the bent pipe after it has been passed through a resin path 18. a winding surface of the roving 17 can be made into a thing crossing at right angles with an axial tangent line of the core metal at a winding position by making the core metal of the bent pipe turn. Therefore, favorable winding can be performed without reciprocating the roving largely in the longitudinal direction of the core metal.
