Abstract
A block suction apparatus for fixing plate-shaped work pieces on a fixing beam or fixing table using under-pressure has at least one support surface provided with a sealing plate having a sealing lip about its periphery. The sealing lip delimits a suction chamber and least one supporting element is provided within the suction chamber. At least one additional supporting element is also provided and is located in the direct vicinity of the sealing lip. Sagging of sections of a plate being lifted by the apparatus which project past the block suction apparatus is thereby reduced and the edge of the plate can therefore be processed with greater accuracy.
