Abstract

PURPOSE: To automatically produce a tapered tube material with a non-circle cross- section simply and accurately by a mechanical force by means of a mandrel having a small-diameter tapered section and a large-diameter tapered section with a circle section at both ends thereof sandwiching an intermediate portion with a non-circle cross-section.
CONSTITUTION: A mandrel used is provided with a tapered non-circle cross-section 11 oval in the cross-section at an intermediate section and a small-diameter tapered section 12 and a large-diameter tapered section 13 circle in the cross-section at both ends. This mandrel 1 is grasped between a molding base 22 (composed of an elastic material) of a molding apparatus 2 and a metal press base 23 is rotated smoothly through tapered section 12 and 13. Under such a condition, a prepreg 3 is fed and automatically wound therearound.
