ABSTRACT:
A system for the profile machining of slabs (23) of marble, stone, glass and the like, using templates (31), comprises a plurality of mechanically adjustable pneumatically operating distance pieces or supporting blocks (1). Each distance piece or supporting block is adjustable for height by means of a screw (8) and nut (6) arrangement and is provided with suction seals (11) on its end surface to support the slab, (15, 16) on an annular step to fix the machining template, and (3) on its base to fix the assembly of slab and distance piece firmly to the workbench, as the slab is being machined. All the suction seals (3, 11, 15, 16) are connected to suction tubes (24) that terminate in a connecting nipple that is connected to a pneumatic vacuum source.
