Abstract

PURPOSE:To produce an elongate element with a satisfactory woodgrain pattern, by extruding simultaneously an elongate element main body from a main extruder and skin forming resins from a sub-extruder so that the resins are provided on the surface of the elongate element main body adjacent to a discharge port of the main extruder. CONSTITUTION:The resin 4 comprising a synthetic resin 5, a stabilizer 6 and a pigment 7 is fed into a hopper 3 of the main extruder 1 where is melted and kneaded, and is extruded via a shaping mold 12 from the discharge port into the elongate element main body. On the other hand, the light colored resin 10 and dark colored resin 11 that comprise the resin 5, the stabilizer 6 and the pigment 7 are fed into a hopper 9 of the sub-extruder 8, and are kneaded. The light colored resin 10 and the dark colored resin 11 are alternatingly discharged from the elongate discharge port formed in conformity with the width of the elongate element with the extrusion rate at the center being greater than that at the opposite sides so that the resins 10, 11 are extruded integrally with the elongate element main body adjacent to the discharge port 2 of the main extruder 1. Thus the grain pattern would not be discontinuous, and therefore a satisfactory woodgrain pattern can be obtained in a stabilized manner.
