LINE FOR MANUFACTURING THE FACING TILES MADE OF NATURAL STONE Russian patent published in 1995 - IPC

FIELD: manufacture of building materials. SUBSTANCE: line for manufacturing the facing tiles of natural stone has charging assembly with the mechanism for feeding tile-blanks, technological fixtures for processing the back and face sides of the tile-blanks correspondingly, mechanism for the tile-blank turning, two technological fixtures for the facet removal, mechanism for the tile-blank turning over, discharging assembly with the mechanism for the ready-made article withdrawal and fixture for the tile-blank transportation. The technological fixture for processing the back side of tile-blanks is made in the form of a gang-saw cutting head for the groove threading on the back side of tile-blanks and spindle assemblies with working heads for calibrating the back side of tile-blanks. The fixture for the tile-blank transportation is made in the form of transport rotors, tightening sprockets and the locked chain conveyer with holders for placing the tile-blanks, with all of them being placed in succession according to the technological process. The chain conveyer bends round the transport rotors and the tightening sprockets. The cutting head for the groove threading on the back side of tile-blanks is steadily placed on the rectilinear portion of the locked conveyer between the charging assembly and the transport rotor. The mechanism for the tile-blank turning is disposed between the technological fixtures for the facet removal on the rectilinear portion of the locked conveyer being after the transport rotor for processing the face side of the tile-blanks. EFFECT: enhanced quality. 4 cl, 7 dwg
