Abstract: A case setup apparatus is generally provided. The apparatus is characterized by a robotic arm and a case engaging apparatus carried by the robotic arm. The case engaging apparatus is characterized by a picker arm assembly for picking a case blank from a source of case blanks, and a rack arm assembly for attaching to a picked case blank. The picker arm assembly is fixedly supported within the case engaging apparatus and the rack arm assembly is pivotably supported, relative to the picker arm assembly, within the case engaging apparatus. A flap folding subassembly is provided and translatably supported within the case engaging apparatus for reversible travel parallel to the picker arm assembly. The subassembly includes flap engaging members, a flap engaging member of the flap engaging members being forwardly extendable to disassociate adjacent flaps of a case blank in advance of folding a flap by the flap engaging members.
