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 ).
