In the initial press, the container is deformed by an arrangement of movable dies and tension-relieving rams into a shape suitable to fit into a compaction chamber in the main press. After the container is collapsed by the dies and rams of the initial press, the initial press is opened and the collapsed container is deposited into the compaction chamber of the main press where it is compacted into a disk-like pellets and discharged from the compaction chamber.
