  • Patent number: 4372065
    Abstract: A pressing table has a main pressing surface element and a pivotable additional pressing table surface element, and a blower capable of applying suction or blowing action selectively to one or other of the pressing table surface portions. Change over from suction to blowing is achieved by the action of the blower fan discharge air in response to triggering by a solenoid thruster, and the blowing action is held on by the airstream until the blower fan stops. Selection of the additional pressing table surface element for the blowing or suction action is automatic in response to pivoting of the additional element from a rest position to an operative position.
