Definitions

  • Roof tiles are generally made of concrete and, in recent years, considerable efforts have been made to manufacture tiles having distinctive profiles and colours such that an improved appearance on a roof may be obtained.
  • the tile forming material may be supplied to the hopper by means of an elongate rotating screw conveyer which is effective both to mix the tile-forming material and to pass it to the hopper.
  • the coloured pigments for the body may be added to the material within the conveyor at an appropriate point along its length such that the required degree of mixing of each pigment occurs. The further along the conveyor the pigment is added, the less mixing there will be with the body material.
  • Different pigments may be added to the material at appropriately spaced intervals in time such that desired colour variations of the finished tiles are achieved. The time intervals may be regularly or randomly spaced.
  • the degree of mixing of each pigment with the material in the conveyor will affect the colour variations in each tile, while the time intervals for which the pigments are added to the material and the degree of self mixing in the hopper may change the predominant base colour throughout a production run.
  • the material may be mixed in a single batch mixer in which case a first pigment is added to one batch, a second pigment to the next and so forth, differently coloured material from subsequent batches being partially mixed in either the hopper or on a conveyer.
  • tile forming apparatus includes a hopper 1 adapted to receive tile forming material, e.g. concrete mortar, supplied from a feed conveyor 2 via a chute 3.
  • the conveyor 2 includes inlets 4 for dry sand/cement mix and water, and a rotating screw 5 adapted to mix the mortar and urge it towards an outlet 6, disposed above the chute 3.
  • a rotating paddle 7 within the hopper urges the mortar down towards a roller 9 which compresses the material onto a succession of pallets 8.
  • the pallets 8 are linked together and driven rightwardly as shown in Figure 1.
  • the mortar then passes under a slipper 10 which finally compresses the mortar and shapes its upper surface.
  • the mortar emerges as a continuous ribbon 11 which is cut into individual tiles 12 by the blade 13 of the guillotine 14. Thereafter, further handling of the tiles is conventional.
