METHOD TO MANUFACTURE MULTICOLOURED TILES AND EQUIPMENT FOR THIS METHOD Russian patent published in 2012 - IPC B28B7/00 

FIELD: construction.

SUBSTANCE: equipment comprises a polymer mould with side walls and a bottom and a template made with the possibility of installation inside the mould and having side walls, external dimensions of which correspond to internal dimensions of side walls of the mould, and at least one partition between them to create compartments. The method to manufacture multicoloured tiles consists in the fact that the cement-sand mixture is laid into the mould in layers, first forming the face layer of the tile by filling the appropriate compartments of the template installed in the mould, to the specified height, with cement-sand mixtures of different colours. Then the template is taken out from the mould, and the bearing layer of the tile is formed by filling of the remaining part of the mould with a one-colour cement-sand mixture, afterwards the mould with the cement-sand mixture is exposed to vibration effect with subsequent hardening of this mixture, and the finished product is extracted from the mould.

EFFECT: invention will make it possible to simplify equipment design and to reduce labour intensiveness of the process for manufacturing of multicoloured tiles.
