ABSTRACT:
This disclosure relates to an apparatus or machine which is especially useful in performing an important article handling function in a semi-automatic production arrangement for inverting and moving interlocking, epoxy bonded blocks. These blocks, commonly referred to as Super Blocks, are cast three at a time on a special steel pallet having accurately positioned cavities. During the casting process eight alignment pins or protrusions are formed on the bottom of each block while at the same time matching alignment dimples or depressions are formed on the top of each block. The semi-cured blocks are inverted by the disclosed apparatus to avoid damage to the alignment pins when the blocks are placed on an exit conveyor. The same block inversion or transfer operation conveniently strips the three blocks off of each of the steel pallets making them ready for the next casting cycle.
