APPARATUS AND METHOD FOR CREASING A CARTON BOARD

摘要

Apparatus (31) is provided for the creasing of a carton board (30). The apparatus (31) has a body (32) with a front surface (43) from which a creasing tool (41) mounted in the body (32) protrudes. The apparatus (31) has means providing an air pressure differential at the front surface (43) whereby the pressure differential acts across a carton board (30) when disposed across the front surface (43) to force the carton board (30) into deforming contact with the creasing tool (41). Preferably, the pressure differential is provided by suction to a slot (38) in a shoe (35) mounted on the body (32) and providing the front surface (43).
