The shaping machine usually cuts on the forward stroke and does not on the backward stroke. So its not required for the tool to be in contact with the work piece when its on the backward stroke. This is ensured by the Clapper box, a device which is hinged to the ram. The lifting of the cutting tool by the clapper box ensures longer tool life and also accidental scratch or other machining defects on the work piece/final product.
The Clapper was created in 1986.
