Abstract: A plurality of flat, similar articles, such as, by way of example, individual slices of sausage which have been severed from an elongate substantially cylindrical sausage-stuffed casing, are randomly deposited onto a conveyor and then advanced in coplanar relationship to an accumulator station where predetermined numbers of articles are divided into individual groups, and each group of articles is advanced onto a carrier member for and which is unique to a particular group of articles, the carrier-member supported groups are advanced one-at-a-time to a stacking station where the articles of each succeeding group are deposited onto the articles of each preceding group until a predetermined number of groups of articles have been vertically stacked, after which the entire stack is released onto a conveyor for further processing.
