ABSTRACT:
Improved extrusion apparatus is shown for the preparation of a rod-like body from a coal-containing particulate mixture. Control mechanisms are disclosed for automatically controlling the throughput resistance experienced by the rod-like (or a developing version thereof) body through a die. Portions of the die wall near the outlet end thereof are adapted for inward displacement in response to these control mechanisms. This embodiment may also be coupled with a longitudinally movable die and control means for adjusting the length of the consolidating coal-containing mixture in contact with the surface of the movable die.
