  "abstract": "Elastically deformable suction plates are provided for lifting and transporting delicate goods such as "fresh" concrete interlocking paving stones. In said suction plates, the total suction space is divided into numerous separate suction chambers which are totally enclosed. The design of such a suction plate and the vulcanization mould needed for its production are described.",
