ABSTRACT:
In a reciprocating piston press where a compressing piston operates in a nonuniform manner, the piston cooperates with conveyor prongs which move material into the path of the piston. The conveyor prongs are guided by a crank and rocker linkage mechanism by way of elliptical gear wheels for movement around a kidney-shaped orbit. The prongs perform a more rapid motion in the region of a fill opening for charging material into a compaction channel containing the compressing piston. The reciprocating piston press is, in particular, employed for compacting cardboard waste in combination with a feeder space which opens into the compaction channel for charging cardboard waste into the channel. The feeder space and piston press are located in a stationary housing.
