Abstract
Apparatus for adhering thermally-softenable particles to one another to form a plastic body has a molding tool reciprocable in a chamber for double piston action on a heated gas in the chamber. The molding tool defines a mold with opposite, gas-permeable walls in the directions of the reciprocation for receiving the particles. The double piston action of the reciprocation of the molding tool then forces the heated gas through the mold and particles therein to thermally soften the particles for adhering into the body.
