Apparatus for shingling stackable items and particularly food items such as frozen food patties in spaced successive groups of a predetermined plurality of items in each group arranged in edge overlap for easy processing such as pick-up in vertical stacks. The apparatus supplies the items in at least one row and transfers the items to a shingling conveyor that receives the items in overlapped groups. The disclosure also includes first speed control means for periodically operating the shingling conveyor at a speed less than the transfer conveyor to assemble the items in groups in which successive items in each group have overlapped edges and second speed control means for periodically operating the shingling conveyor at a speed greater than the transfer conveyor at the conclusion of the assembling of each group to separate groups.
