METHOD PARTICULARLY FOR DECORATING CERAMIC TILES AND RELATIVE SILK-SCREEN PRINTING MACHINE

摘要

The method for silk-screen printing of ceramic tiles comprises propelling the tiles (A, B, C, D; E, F) by side traction for positioning in a silk-screen printing station (18, 18A, 20, 21), silk-screen printing of the tiles, a plurality of independent positioning devices (2, 3, 4, 5, 6, 7, 15) being provided whereby each tile to be printed is taken by a positioning device when it is still engaged by the preceding positioning device; the method allows simultaneous silk-screen printing of a group of at least two tiles as well as silk-screen printing of a single tile by means of a plurality of positioning devices; the invention further comprises a silk-screen printing machine comprising a conveyor device (1) for feeding the tiles to a silk-screen printing means, at least two positioning devices (2, 3, 4, 5, 6, 7, 15) having consecutive pairs of endless belts (4, 5) acting on the edges of the tiles in a plane comprising, or laying substantially parallel to, the surface of the tile to be printed and straddling the conveyor device.
