PURPOSE:To obtain an intermediate for a tapered pipe by winding a sheet fiber-reinforced thermoplastic resin-impregnated material on the outer surface of a tapered mandrel. CONSTITUTION:A tapered mandrel 31 is provided between an upper plate 11 and a lower plate 12. A guide body 32 is provided between the upper plate 11 and the lower plate 12 through the mandrel 31. While one of the upper plate 11 and the lower plate 12 is moved toward the other, the mandrel 31 is rolled. At this time, a fiber-reinforced thermoplastic resin-impregnated material 41 is wound on the outer peripheral surface of the mandrel 31 by the guide body 32. At this time, one of the upper plate 11 and the lower plate 12 is shaken and swung with the movement of the other in the width and length directions, In this manner, a sector locus of the development of the tapered mandrel 31 can be obtained. |
