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.

Abstract

Un procédé de fabrication de tuiles de toiture consiste à introduire le matériau formant les tuiles dans une trémie (1) en permettant la décharge successive sur une série de palettes mobiles consécutives (8) formant un ruban de base (11) qui est découpé en tuiles individuelles (12). Un ou plusieurs pigments de coloration du corps sont ajoutés au matériau avant son introduction dans la trémie (1), par exemple dans un convoyeur à vis sans fin (2) conduisant à la trémie, et on ajoute un ou plusieurs pigments secondaires de coloration au matériau dans la trémie (1) de manière à obtenir des tuiles présentant des rayures en surface.

Claims (10)

1. Procédé pour la fabrication de tuiles (12) de toit en béton, dans lequel un pigment coloré est ajouté à une quantité de mortier formant la substance principale de la tuile et mélangé à celui-ci, la quantité de mortier est introduite dans une trémie (1), un matériau secondaire est ajouté à la quantité de mortier dans la trémie, le matériau secondaire comprenant un second pigment coloré dont la couleur est différente de celle du premier pigment coloré, la quantité de mortier et le matériau secondaire sont partiellement mélangés dans la trémie de façon à fournir une masse de mortier ayant une couleur bigarrée comprenant des zones importantes dont la couleur est déterminée de manière prédominante par le premier pigment et des zones dont la couleur est déterminée de manière prédominante par le second pigment, et la masse de mortier est extrudée sur une succession de palettes (8) mobiles pour former un ruban de base (11) qui est comprimé et coupé en tuiles individuelles (12), les tuiles ayant une couleur bigarrée, caractérisé en ce que le matériau secondaire est une seconde quantité de mortier formant la substance principale, le second pigment coloré étant ajouté à la seconde quantité de mortier et au moins partiellement mélangé à celui-ci avant d'être introduit dans la trémie (1), et le dispositif étant tel qu'à travers la masse de mortier qui est extrudé pour former les tuiles (12), il y a, en plus des zones importantes dont la couleur est déterminée de manière prédominante par le premier pigment, des zones importantes dont la couleur est déterminée de manière prédominante par le second pigment et des zones importantes dont la couleur est déterminée par un mélange des premier et second pigments, de sorte que les tuiles ont une couleur de substance bigarrée correspondante.
2. Procédé selon la revendication 1, caractérisé en ce qu'un flux de mortier est fourni à la trémie (1) et les premier et second pigments sont par intermittence délivrés dans le flux de telle façon que, dans le flux alimentant la trémie (1 ), il y a des quantités de mortier qui sont colorées de manière prédominante par le premier pigment et des quantités qui sont colorées de manière prédominante par le second pigment.
3. Procédé selon la revendication 2, caractérisé en ce que le premier et le second pigments sont introduits de façon telle qu'il y a un mélange incomplet avec leurs quantités respectives de mortier avant de passer dans la trémie (1).
4. Procédé selon la revendication 3, caractérisé en ce que le flux de mortier est obtenu par un convoyeur (5) d'alimentation à vis, et les pigments sont introduits dans le mortier dans des positions (15) situées vers la sortie (6) du convoyeur.
5. Procédé selon la revendication 1, caractérisé en ce que le premier et le second pigments sont prémélangés avec leurs quantités respectives de mortier et disposés en charges (20) qui sont introduites par intermittence dans la trémie (1).
6. Procédé selon l'une quelconque des revendications précédentes, caractérisé en ce qu'au moins un pigment coloré différent supplémentaire est introduit dans le mortier de la même manière que le second pigment.
7. Procédé selon l'une quelconque des revendications précédentes, caractérisé en ce qu'un pigment colorant de surface est introduit dans la trémie (1) de manière à fournir des stries de couleur sur les surfaces supérieures des tuiles (12) en plus de la couleur de la substance bigarrée produite par les autres pigments.
8. Procédé selon la revendication 7, caractérisé en ce que le pigment colorant de surface est ajouté à l'aide de moyens (16) d'alimentation aboutissant au-dessus du niveau du mortier dans la trémie (1).
9. Procédé selon la revendication 8, caractérisé en ce qu'il y a un rouleau (9) dans la trémie (1) disposé pour comprimer le mortier contre les palettes (8) et les moyens (18) d'alimentation sont positionnés au-dessus du rouleau (9).
10. Procédé selon la revendication 8 ou 9, caractérisé en ce que les moyens d'alimentation (16) ont un mouvement de va et vient latéralement par rapport à la trémie (1).
