Abstract
A device for blocking workpieces for the processing and/or coating thereof, has a support surface for positioning the workpiece to be blocked, a blocking station in which the workpiece can be blocked on a blocking piece by a temporarily deformable blocking material, and a transport device which has a retaining head for the workpiece and by which a relative movement can be created between the workpiece being retained at the retaining head, and the support surface and the blocking station. The transport device has at least four position-controlled movement axes, by which to position the workpiece in a defined manner in consideration of the orientation and geometric information relative to a blocking piece located in the blocking station, and can be retained in the defined relative position to the blocking piece during blocking while leaving a blocking material accommodation gap between the workpiece and the blocking piece.
