摘要： In a die for ceramic products with an elastomeric membrane (13) sucked against the upper surface (3) of the die, for better and more rapidly anchoring said membrane (13) to said die (3) there are provided peripherally thereof: a ledge (1) running outwardly relative to the periphery of the die (3) and provided with a groove (5) and/or holes leading to a sucking system constituted by a pipe (9) likewise running peripherally relative to the die (3) outwardly thereof, and a groove (17) provided in the outer edge of the die (3) inwardly of the ledge (1) and having holes (19) on its bottom, said holes communicating with a peripheral chamber (21) in which the vacuum is produced. Both the ledge (1) and the groove (17) suck in appropriate beads (15) and (23) which may be continuous or constituted by projections or spaced "buttons" provided respectively in the corresponding areas (11) and (13) of the elastomeric membrane.
Said elastomeric membrane (13) is preformed for efficiently adhering to said suction fixing system with considerable saving of time and greater efficiency.
