Abstract: A machine for denesting stacked packaging baskets receives a stack of nested packaging baskets via a first conveyer belt. The stack of packaging baskets lies on its side. A gripper is reciprocatingly moved along a trajectory toward and away from the stack. During each reciprocating motion of the gripper, the first basket in the stack is gripped and removed by the gripper from the stack. The denested basket is then rotated into an upright position by engaging against a turning rod located above the trajectory of the gripper. The uprighted basket is then deposited on a second conveyer belt for transport to a location where product is added.
