ABSTRACT:
The radial compression molding apparatus according to the invention is provided with a plurality of complementary die segments which define a cavity in which moldable material is to be introduced. The die segments are movable concurrently between a first inoperative position and a final compression position so as to be adapted to compress the moldable material within the cavity from a first volume to a final volume along a plurality of radial directions which are substantially perpendicular to a common longitudinal axis. Each die segment consists of a plurality of separately operable segment portions which are superimposed in a direction parallel to said common longitudinal axis so as to permit to obtain molded articles consisting of a plurality of contiguous longitudinal portions having different cross sections and equal density.
