Abstract: High speed dairy casing methods and apparatus assemble columns of filled containers arriving on two infeed conveyors, transfer one, two or more columns to an assembly ramp adjoining each conveyor, and then sweep the assembled columns from the conveyor and the ramp together across the ramp to an adjacent loading zone for casing, leaving the assembly ramp free for assembling succeeding columns while case loading is proceeding. Preferably two infeed conveyors deliver filled containers into two separate assembly zones with their ramps flanking a central loading zone, and a pusher with two extended positions propels each single column from its conveyor onto the assembly ramp, and then propels the final column with the assembled columns together across the ramp to the loading zone as the pusher advances to its remote extended position.
