Abstract

A method for moulding uniformly compacted tiles comprises forming a test tile (11), measuring the hardness or compactness of said test tile at a large number of points on its surface, locally varying the thickness of the punch (1) for forming the reverse face of the tile in those regions of the punch corresponding to those tile hardness values which most differ from the mean value of the largest number of measurements of approximately equal value. Said three operations, namely forming, measuring and varying, are then repeated until a substantially uniformly compacted tile (111) is obtained, after which other tiles (111) are continuously moulded until the pressing conditions change.
