Abstract

PURPOSE:To obtain easily a resin form having a core member by a method wherein the core member is introduced continuously into a mold upon extrusion molding and is coated by supplying a resin simultaneously. CONSTITUTION:A plurality of filaments 1, constituting core members of respective sides of sections of an extruded form and wound into hooplike shapes, are introduced into a crosshead die 11 through slots 12. Respective filaments 1 are converged further into sectional configurations of the form along core metals 13. Simultaneously, molten resin 21 is supplied from a cylinder 10 through a head 14 to coat the filaments 1, subsequently, both of them are extruded through the base 15 to obtain a resin coated form. A fiber reinforced form having a complicated configuration may be obtained easily.
