Abstract
A device for blocking workpieces has an aligning station that includes a workpiece support for aligning a workpiece. A blocking station comprises a block piece mount and serves to block the aligned workpiece by use of a block material on a block piece, which can be mounted in the block piece mount in a centered manner in relation to a substantially vertically extending blocker axis. A workpiece carriage carries a holding head for the workpiece and is suitably guided and driven to transport the workpiece from the aligning station to the blocking station to position the workpiece along the blocker axis in a defined manner relative to the block piece held in the block piece mount, and to hold the workpiece during blocking in the defined relative position to the block piece with a gap between workpiece and body piece.
