  • the conduits 32 are individually slidably supported on guides 320 perpendicular to the axis of the conveyor belt 2.
  • the powders 33 are deposited by the feed conduits 32 in prearranged or random manner on the collection surface 31.
  • the manner in which the powders 33 are distributed on the collection surface 31 can be controlled by modifying the sequences and times of opening of the various distribution conduits 32, which are provided with shut-off gate valves, not shown.
  • the veins typical of a slab of natural stone can be reproduced by suitable horizontal paths which the conduits 32 are made to traverse above the collection surface 31. It is however possible to use fixed powder feed conduits, although the use of movable conduits is preferable.
  • the collection surface 31 is disposed substantially horizontal and is preferably provided with opposing vertical side walls 36 for retaining the powders 33.
  • the pusher 30, shown in section in the figures, is positioned transverse to the two side walls 36, above the collection surface 31.

  • the hopper 34 has the shape of a rectangular parallelepiped having the two larger faces, i.e. the front face 34a and the rear face 34b, normal to the direction of advancement of the belt 2 and positioned at a distance "B" apart equal to the thickness of the continuous powder strip 100 which is to be obtained and then compacted.
  • the height of the hopper 34 ( Figure 1 ) which is just less than the distance between the collection surface 31 and the advancement plane of the belt 2, is chosen on the basis of the dimensions of the plant 1 such as to ensure that powder 33 is present along the entire width "L" of the discharge aperture 38 ( Figure 2).

  • the front face 34a can be made movable along the powder advancement direction to enable the distance B between the front face 34a and rear face 34b to be varied.
  • the rear face 34b or both faces can be made movable.
  • the front face 34a and/or the rear face 34b is inclined away from a position perpendicular to the fall-on surface to obtain a lower discharge aperture 38 wider than the upper loading aperture 37 ( Figures 9A-9D).

  • the distance "B" at the discharge aperture 38 should be substantially equal to said thickness "S" of the powder strip 100 so that, by virtue of the roller 41 , the powders 33 can be advantageously transferred onto the belt 2 while maintaining substantially unaltered the arrangement which they possessed within the hopper 34; this advantage is particularly useful when said arrangement is able to give the powder strip 100 a predetermined desired graphical appearance, for example the typical veining of natural stone.
  • the rotary roller 41 can be mounted idly such that its rotation is induced by friction with the powders 33 as these pass from the hopper 34 to the belt 2.
  • said roller 41 can be motorized and rotated such that its peripheral speed is equal to and in the same direction as the advancement speed of the belt 2; this can be achieved by connecting the roller 41 to an independent gearmotor, or connecting it via a suitable transmission system to the drive members for the belt 2.

  • the mass of powders 33 on arriving in the hopper 34 by gravity, settles gradually from the bottom thereof upwards towards the discharge aperture 38.
  • the mass of powders 33 deposited continuously in the hopper 34 reproduces throughout its bulk a slab of natural stone, lying vertically in a direction perpendicular to the belt 2.
