ABSTRACT:
An apparatus for reproducing compaction and ejection events in a plurality of press machines is disclosed. Each press machine has at least one die opening wherein a compound is placed to be compressed at least once between upper and lower punches sliding inside the said die whereupon the compressed compound is ejected from the die cavity. The apparatus and methods ensure that the plurality of compression and ejection events have the same exact speed, profile curvature, and pressure or force as on any pre-specified press machine by matching the timing and geometrical path of the punch movements as well as the depth of fill of the die. The linear speed of the punches is matched by a computer controlling the programmable motor of the die carrier. The path profiles of the punches are matched mechanically by means of interchangeable rollers and cams with the predefined geometry. The pressure or forces of the matching events are controlled and adjusted by means of the positioning of the lower punch in the die.
