(under subclass 179) Apparatus in which the casing supports (1) means which prevents the compacted material from expanding in the direction toward the pressing platen after the material has been compressed, or (2) means adjacent the filling opening and above the path of movement of the pressing platen such that, as the plunger retracts from the compressing position, the material above the top of the pressing platen not compressed thereby will be forced downwardly into the path which the pressing platen would pursue in the succeeding stroke.
