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.
Claims13
A low-pressure suction plate made of elastically deformable material and suitable for lifting and transporting concrete interlocking paving stones immediately after their manufacture, which suction plate comprises an elastomer body member for connection to a rigid low pressure connecting means, such body member comprising a continuous sealing lip extending around the outer contour of said body member and enclosing a total suction space which is divided into a plurality of elongated suction chambers each having a continuous seal therearound and forming an individually sealed suction space when said suction plate is placed on a surface of an object to be lifted, each of said suction chambers being in flow communication with said low-pressure connection means through at least one connecting channel, said channel having at least one change in the direction along its length.
