Abstract

PURPOSE: To readily obtain the roller of light weight and high strength by drawing both ends of a blank pipe then fitting the same into the dies which have the molding holes assuming a complementary shape with the roller outside diameter and are fitted with a movable die assuming a complementay shape with the roller end and bulging the same by pressure fluid.
CONSTITUTION: Both ends of a blank pipe are drawn to form the pipe body A' having a large-diameter part 1 at its center and tapered parts 2 and small-diameter parts 2 at its both ends. The pipe body A' is then fitted into the two-split dies B having the molding holes assuming a complementary shape with the intended roller outside shape and pressure fluid 12 is pressure-fed into the pipe body A' to bulge the same. At the same time, a movable die 6 provided with the molding hole assuming a complementary shape with the shape of one end of the roller to be molded is slidably fitted to the one end in said dies B and one end of the pipe body A' is fitted into the molding hole of the die 6 and is moved forcedly in the axial line direction by the pressure fluid, whereby the roller A" of light weight and of the thicknesses (b) and (c) larger than the thickness (a) suited for copying machines, etc. is readily obtained by the extremely simple operation.
