ABSTRACT:
A block forming apparatus comprises a frame, a compression case and compression bodies. The compression case is movably engaged with the frame in a manner enabling movement of the compression case along a longitudinal reference axis of the compression case. The compression case has a compression body receiving passage extending between opposed end faces thereof along the longitudinal reference axis. The compression case includes a media fill opening within an upper wall thereof and a block discharge opening within a lower wall thereof. The media fill opening and the block discharge opening are each communicative with the compression body receiving passage. The compression bodies are movably mounted within the compression body receiving passage of the compression case in a manner enabling movement of said compression bodies along the longitudinal reference axis of the compression case.
