Process and device for making tiles, slabs and similar construction blocks by means of pressing a powder mixture.

摘要

The manufacture of tiles is effected by compressing powder in a cavity defined by two vertical plates (8, 10) forming the faces of the tile, and one (8) of which can move with respect to the other (10), perpendicularly to its plane, under the action of a cylinder (4) and by cheeks (15, 27, 28) forming the edges of the tile and capable of moving, under the action of a cylinder (24), jointly with the plate (28), at half-speed. One (15) of the cheeks can move under the action of a cylinder (21) parallel to the planes of the plates (8, 10) in order to remove the tile from the cavity. Application, in particular, to the manufacture of recessed tiles from a mixture of powder, plaster and gypsum.
