ABSTRACT:
During stripping of a cement block from a mold in a cement block forming machine by shoes of a stripper head, the head is driven by gravity and its distance from a pallet receiver structure, including a pallet receiving the cement block, is limited by hydraulic, collapsible stops. The stops collapse during stripping a distance sufficient to slump the block. The amount of collapse during the stripping time interval is controlled by adjustable hydraulic flow means under constant pressure.
