  DISK FOR CRYSTALLIZING MARBLE OR THE LIKE

  The present invention relates to a disk for crystallising marble or the like, such as granite, or

  in a more general way, all porous stones.

  At present crystallization, or polishing, of marble or the like is carried out with the aid of a kind of waxy, more commonly known as a single-blade machine, comprising a horizontal circular plate driven in rotation and provided on its lower face turned towards the ground. a hooking surface usually consisting of "Velcro" on which is placed by hand a layer of steel wool, usually ordinary, the steel wool is in the form of a ribbon that is next agency a winding

he licodal.

  Such work is obviously tedious, repetitive since it is periodically necessary to remove the used wool and replace it, impractical and wasted time. In addition, such an arrangement is not an optimal efficiency and does not allow to work with a high speed of rotation

of the wool disc.

  The object of the invention is precisely to overcome these various disadvantages by proposing a new disk structure to crystallize offering both increased efficiency

and a great ease of use.

  For this purpose, the subject of the invention is a disc for crystallising marble or the like, characterized in that it consists of a disk made of metal fabric or the like provided on its attachment face with a drive plate. -2- a waxy or the like of the type with "Velcro" fastening or the like, at least one embossed wire mesh and, on its opposite face, at least one embossed wire mesh of different characteristics or not of those from the embossed canvases on the other side. Such a disk, manufactured in the factory, is immediately ready for use. It instantly attaches to a waxy or single-sided workout pad and works more efficiently and, most importantly, at a good rotational speed.

  higher than traditional discs.

  Other features and benefits will emerge

  of the following description of an embodiment of a

  disk according to the invention, description given as a

  example only and with reference to the appended drawing in which:

  - Figure 1 is a top view of a disc crys-

  talliser according to the invention; - Figure 2 is an enlarged sectional view along the line II-II of the disk of Figure 1, and - Figure 3 is a schematic axial sectional vertical view of a wiper equipped with a disk according to the invention. The disk to be crystallized represented in FIGS. 1 and 2 consists of a metal cloth 1 in the form of a circular disc pierced at its center with a recess as well.

circular 2.

  The fabric of the disk 1 is preferably made of stainless steel and has a thickness of the order of 1 mm with an outside diameter of the order of 400 mm and a diameter of

  the central recess 2 of the order of 120 mm.

  The annular disk 1 is covered, on its face, the destiny to be hooked on the underside of a drive plate 3 (FIG. 3) of a waxy or monobrush 4, of two superposed embossed webs or meshes 5, 6, formed of wires of a thickness of the order of 25 to 30 hundredths of a millimeter, in

preferably stainless steel.

  On its opposite face 1b, the annular disc I is covered with four superposed embossed webs or meshes 7, formed of threads each comprising eight filaments or strands.

  from 8 to 10 hundredths of a millimeter, preferably stainless steel.

  The fastening between the central fabric 1 and the embossed fabrics 5 to 10 is advantageously achieved by welding the electric wheel along two peripheral strips of about 1 cm wide for example, respectively outer 11 and inner 12, on each side

of the annular disk 1.

  The disk 1 with its webs is manually applied by pressing its face against the face of the plate 3 provided with the attachment means 13 known under the trade name "velcro" of the waxy machine 4. The plate 3 is rotated by the motor 14 of the polisher, itself

guided by means of a drawbar 15.

  During operation is also used, as is customary, a product to crystallize liquid

or slightly pasty.

  Such a disc is easy to store, ready to use, the stainless steel avoiding any oxidation during the storage period, remarkably easy and quick to set up on the tray 3 (as well as removing when it is out of use), particularly effective because of the regularity and homogeneity of the abrasive working surface (Ib) and allows a rotation speed of the plate, of the order of 800 to 1500 rpm, much higher than that of waxy machines equipped with traditional hand-made disks (180 rpm at the most),

  so that the yield is improved accordingly.

  Finally, the invention is obviously not limited to the embodiment shown and described above but covers all variants, particularly with regard to the dimensions and shape of the disc 1, the nature, characteristics and number of paintings embossed 5 to 10, the thickness and the constitution of the yarns of said teLes, the nature and characteristics of the central fabric 1, the mode of

  fastening the canvases to this central fabric 1.

  On the face the number of the fabrics 5,6 can be greater or less than two, this last figure being revealed

however sufficient.

  Similarly, the embossed webs of the face lb may be in number greater than or less than four and constituted -4- from threads of different threads to that indicated above, the described embodiment however constituting a mode of implementation. particularly effective

of the invention.

  Similarly, it may be possible to consider replacing the central fabric 1 a structure of a different nature but capable of fulfilling the same conditions and provide similar results. Finally, the central recess

  2 may not exist or have very small dimensions.
