ABSTRACT:
Apparatus and method are disclosed for forming tied stacks of block-like objects wherein the blocks are first placed on either one of two independent grouping systems. These first and second grouping systems then supply respectively corresponding grouped blocks to a marshalling area, where successive layers of the stacks are formed in different respective orientations. The successively formed layers are then lifted and stacked one on top of the other. The controls for the apparatus are such that at least two different interlocking patterns of blocks may be formed in the marshalling area by controlling the number of blocks taken from each grouping system and also controlling placement of the blocks in the marshalling area, so that a properly tied stack results.
