摘要：PURPOSE:To obtain a stable enlarged diameter shape by heating a resin tube and raising the temp. of a diameter enlarging jig so as to make the same higher than that of the resin tube to move said jig in a molding direction under rotation. CONSTITUTION:A work 3 is rotated and a heating element 12 is heated and a heating part 13 is moved to the heating position directly under the work 3 and the work 3 is heated to a predetermined temp. range for a predetermined time under rotation. The temp. of a diameter enlarging jig 17 is made higher than that of the region to be molded of the work 3 by the heating part 13. After heating for a predetermined time, the jig holding part 5 fitted with the diameter enlarging jig 17 is moved toward the work 3 at a predetermined speed to enlarge the diameter of the work. When the work 3 is subquently heated at the diameter enlarging position for a predetermined time under rotation, the opening end of the region to be molded of the gradually softened work 3 is perfectly enlarged in a trumpet shape. Thereafter, the heating of the heating element 12 is stopped and the work 3 is cooled by air to be solidified.
