ABSTRACT:
An apparatus for manipulating a workpiece or the like comprising a pair of inger assemblies mounted on a common support. The finger assemblies have belts with contact surfaces arranged in a confronting relationship. A first operating mechanism is provided for moving the finger assemblies along a first axis towards each other to grip a workpiece between the belt contact surfaces. A second operating mechanism is provided for rotating the belts about the first axis in order to impart a corresponding rotation to the workpiece gripped therebetween. A third operating mechanism is provided for moving the belts in either the same or opposite directions in order to impart either translational movement to the workpiece along a second axis perpendicular to the first axis or rotational movement to the workpiece about the second axis. The first, second and third operating mechanisms are operable independently of each other, and the first operating mechanism is operable additionally to move the finger assemblies together in the same direction along the first axis to impart corresponding translational movement to the workpiece and also to move the finger assemblies along the first axis away from each other to release the workpiece from between the contact surfaces.
