- FIG. 1 shows in perspective a cover plate according to the invention
- FIG. 2 is a similar view of another embodiment of the cover plate according to the invention.

- FIG. 15 illustrates in top view, schematically, a second embodiment of the extrusion and rolling steps; and - Figure 16 is a sectional view taken along line XVI-XVI of Figure 15.
- thin plates 1 of black or anthracite color are produced intended for roofing buildings and having the appearance of slate. These plates have a common thickness of the order of 5 to 6 mm in an "flat" embodiment shown in FIG. 1.
- FIG. 2 In another embodiment, shown in Figure 2 without respecting the proportions, they have a current thickness of about 9 mm and they are provided along an edge 2, constituting in service the upper edge of the plate, of hooking reliefs 3 projecting downwards having a height of the order of 8 mm; they also have, on their upper surface, along said upper edge and of the two lateral edges, joint ribs 4.
- the lateral edges have a thickness reduced by approximately half, one from the top, the other from from the bottom, and their ribs 4 are directed upwards for the first and downwards for the second, so as to allow their fitting from one plate to the adjacent plates.
- the lower edge of the plate has a recess adapted to receive the rib 4 of the upper edge of the plates located immediately above.
- the plates 1 typically have dimensions ranging from 200 X 300 mm to 300 X 600 mm, and they are relatively light, with a density of the order of 1.8.
- the upper surface of the plate 1 has irregularities 5 imitating slate, called "slate cleavage".
- the plates 1 are ductile: they have a breaking strength of the order of 14 to 18 MPa, and an elongation at break of at least 0.15%.
- the manufacture of plates 1 will now be described in more detail, with a numerical example.
- the starting paste is made with following constituents, which form a hydrated matrix reinforced by glass fibers:
- Matrix a.l Dry materials: - high quality Portland cement, for example HPR cement: 100 parts by weight
- - black dye iron oxide: approximately 4 parts by weight.
- a.2 Water 35 parts by weight, or 16% by weight relative to dry matter.
- alkali-resistan ⁇ glass fibers present in a proportion of 3.5 by weight relative to the hydrated matrix (dry matter + water).
- These fibers can in particular be fibers having a length of 6 to 12 mm, made up of 200 filaments of 14 ⁇ m in diameter, ie a length / diameter ratio of between 100 and 200 approximately.
- Suitable glass fibers are non-water-soluble sizing fibers commercially available under the trademark "Cemfil”.
- a cross-cutting device 16 forms, from the strip 14, a succession of blocks 6, which are conveyed by a second belt conveyor 17, at higher speed in order to space them apart.
- a third belt conveyor 18 carrying a succession of supports 9 joins obliquely, below, the downstream end of the conveyor 17. The speeds are synchronized so that, at the end of the conveyor 15, each support 9 receives a block 6, always in the same relative position. Each assembly 6-9 then passes over a fourth belt conveyor 19, which takes it through a rolling station 20 shown diagrammatically in FIG. 10.
- the station 20 comprises a train of rollers or rolling 21 to 23 arranged transversely above the conveyor 19, closer and closer to the latter.
- the height of each block 6 is reduced in three stages to a value which is substantially that of the final plate 1 to be obtained.
- Each support 9, at the outlet of the rolling station, in this way carries a blank 7 of small thickness, which is carried by the conveyor 19 to a shaping station 24 shown schematically in Figure 11.
- each support 9 is deposited on a fourth belt conveyor 25 above which is a fifth belt conveyor 26.
- the latter carries at regular intervals bases 27 on each of which is fixed a shaping plate 8, whose sharp peripheral edges are indicated by 28.
- the assemblies 27-8 have only been shown in FIG. 11 on the strand of the conveyor 26 adjacent to the conveyor 25.
- the conveyors 25 and 26 are driven in a synchronized manner so that each shaping plate 8 comes to cover exactly a blank 7 by cutting the periphery to the desired dimensions while conforming the upper surface with the aforementioned slate cleavage.
- the production of the plates 1 of the Figure is identical in all respects to what has been described above, except that the supports 9 are replaced by the supports 10 of Figures 6 to 8 and that the shaping plates 8 include the recesses 12 mentioned above.
- the extrusion carried out in 13 is necessary to give the dough the plasticity required for undergoing rolling and shaping. However, this extrusion has the result of preferentially orienting the glass fibers, whereas it is generally desired to obtain isotropic mechanical properties for the plates 1. It is therefore necessary to reorient the glass fibers after extrusion, this which can be carried out during rolling, as illustrated in Figures 12 to 14 or as illustrated in Figures 15 and 16.
- the extruder 13 comprises at its outlet a chamber or mouth 30 progressively variable section from a circular section (Figure 13) to a flattened section ( Figure 14) having substantially the desired width for the plates 1
- the passage area decreases between these two sections in a ratio of 1 to 5 to 1.
- the glass fibers of the strip 14, and therefore of the blocks 6 after cutting at 16, are preferably oriented in the transverse direction.
- the conveyor 19 is replaced by idle support rollers 31, some of which are arranged below the laminating rollers 21 to 23, and these and / or the rollers 31 are rotated at predetermined speeds. These speeds are chosen so as to accelerate the dough longitudinally, as a function of the reduction in thickness ensured by each rolling roll, so as to keep the width of the blocks 6 substantially constant. This acceleration, in turn, causes the longitudinal reorientation glass fibers, ultimately leading to a substantially homogeneous and isotropic distribution of these fibers.
- the extruder does not include a mouth 30, and the extruded strip 14 has a width much less than that of the plates 1; the glass fibers are then preferably oriented in the longitudinal direction.
- the sectioning 16 is postponed after the shaping station 24, and the strip 14 is continuously deposited on the supports 9 (or 10) at. abutted against each other.
- the supports are carried, without possible sliding, by the conveyor 19. The latter is driven at constant speed, while the laminating rollers 21 to 23 are either driven in synchronization with this conveyor 19, or mounted crazy.
- Silica smoke can be present in proportions ranging from 8 to 12 parts by weight approximately. Its function is to facilitate extrusion by improving the plasticity of the dough, and it also improves the mechanical properties of the final plate. These effects are insufficient below 8 parts by weight, while the plasticity drops excessively, during extrusion, above 12 parts by weight.
- the silica smoke can be replaced, in the same proportions, by other ultrafine particles, in particular by metakaolin, which is kaolin treated at 800 ° C. so that it becomes pozzolanic.
- ultrafine particles in particular by metakaolin, which is kaolin treated at 800 ° C. so that it becomes pozzolanic.
- metakaolin which is kaolin treated at 800 ° C. so that it becomes pozzolanic.
- ultrafine particles in particular by metakaolin, which is kaolin treated at 800 ° C. so that it becomes pozzolanic.
- metakaolin which is kaolin treated at 800 ° C. so that it becomes pozzolanic.
- the term “ultrafine particles” is generally understood to mean particles whose BET specific surface area is between 10 and 30 m 2 / g.
- the sand can be present in proportions of 80 to 120 parts by weight. It plays an anti-cracking role. Below 80 parts by weight, a tendency to crack the plates 1 appears. Above 120 parts by weight, a loss of the mechanical properties of the plates 1 is observed.
- the water can be present in a narrow fork between 0.30 and 0.40 relative to the weight of the cement. Below 0.30, it is no longer possible to use the dough, and above 0.40, free water remains in the dough, which leads to excessive porosity of the product. finished.
- the glass fibers must be present in a proportion of approximately 3 to 4% relative to the weight of the hydrated matrix. Below 3%, the reinforcement is insufficient, and above 4% there appear rheological difficulties, that is to say that the dough has insufficient plasticity for its treatment of rolling and conformation described above.
