Abstract
A roof tile (9) having contoured interlocking regions (20) along its side edges is provided with a plurality of relatively shallow closely spaced, longitudinally extending grooves on its upper surface (19) and optionally upwardly extending grooves on its lower end face (21). An improved appearance on a roof is obtained, and through the provision of dark brown streaks on a light brown base a roof tile may be given a wooden appearance. In a process and apparatus for the manufacture of such tiles, a slipper compressing tile forming material is provided with closely spaced ridges which form the grooves on the tiles.
Claims15
A process for manufacturing roof tiles wherein tile forming material is discharged onto a succession of pallets to form a base ribbon, and the ribbon is compressed by means of a slipper and is subsequently cut into individual tiles, wherein the tiles are provided over at least a major part of the upper surface thereof with a plurality of relatively shallow, closely spaced, longitudinally extending grooves by means of ridges provided on the slipper contacting the ribbon.
A process for manufacturing roof tiles wherein tile forming material is discharged onto a succession of pallets to form a base ribbon, and the ribbon is compressed by means of a slipper and is subsequently cut into individual tiles, wherein the tiles are provided over at least a major part of the upper surface thereof with a plurality of relatively shallow, closely spaced, longitudinally extending grooves by means of ridges provided on the slipper contacting the ribbon, and wherein said cut forms closely spaced grooves on at least one surface edge of said tiles.
Apparatus for manufacturing roof tiles comprising means for transporting a succession of pallets in a longitudinal direction, means for discharging tile forming material onto the pallets to form a ribbon, a slipper for compressing the ribbon, and means for cutting the ribbon into individual tiles, wherein the slipper is provided over the major part of the surface thereof which contacts the ribbon with a plurality of relatively small, closely spaced, longitudinally extending ridges.
Apparatus for manufacturing roof tiles comprising means for transporting a succession of pallets in a longitudinal direction, means for discharging tile forming material onto the pallets to form a ribbon, a slipper for compressing the ribbon, and means for cutting the ribbon into individual tiles, wherein the slipper is provided over the major part of the surface thereof which contacts the ribbon with a plurality of relatively small, closely spaced, longitudinally extending ridges, and wherein said cutting means is shaped so as to form closely spaced grooves on at least one surface of the tile.
