  • the DE 10024913 A1 describes for a cutting machine, a holding device which has vacuum applied to suction cups.
  • the US 6024392 describes a suction gripper in which an elastic suction cup is fixed to a piston member which is slidably held in a bore and is pushed under load against an object in the bore, thereby opening a flow path for negative pressure.
