Abstract

An isostatic buffer for pressing tiles comprising a base (12), a plate (13) applied to an upper face of the base and a cladding of a yieldable material (26) applied to said upper face (14) of the base to incorporate at least partially said plate and make a pressing surface of the buffer, the base comprising at least a conduit (16, 18) that leads by means of an opening (16c) onto the upper face of the base to feed incompressible fluid to an isostatic circuit formed between the plate (13) and the yieldable cladding (26). The isostatic circuit is confined between the cladding of a yieldable material (26) and an upper face of the plate (13) opposite the base, said plate being provided with a through hole (20) superimposed with said opening (16c) of the conduit to convey the incompressible fluid in the isostatic circuit.
