Embodiment Construction

[0159] refer to figure 1 , 2 and 3, the device 1 comprises a thin metal sheet 2 which is annularly closed in a cylindrical tubular shape and whose outer surface constitutes the transfer surface 3 . The inner surface 4 of the sheet 2 is supported by a tubular body 5 made of an electrically and thermally insulating material resistant to temperatures of at least 250°C, preferably 350°C.

[0160] The tubular body 5 together with the lamellae 2 is rotatable about its axis 7 in the direction of the arrow 6 by means of a drive not shown.

[0161] On the outside of the high zone of the transfer surface 3 there are inkjet means 8 activated by computer means C. As shown in FIG. Further downstream, in a descending part of the surface 3 , which is directed downwards, there is provided a distribution device 11 suitable for projecting granular material 12 against the surface 3 .

[0162] The transfer zone 15 is configured in the lower part of the transfer surface 3 , facing the upper sur...

Abstract

A method for applying a pattern (21, 57) of granular material (12, 12b, 12c, 12d) on a receiving surface (13), comprising in sequence associating said granular material (12, 12b, 12c, 12d) with a transferring surface (3) together with a liquid aggregating phase (9, 20) and according a prefiguration (10, 10b, 18, 56) of said pattern; facing said transferring surface (3) carrying said granular material (12, 12b, 12c, 12d) and said liquid phase (9, 20) to said receiving surface (13) in a transferring zone (15, 45); the method further comprises heating at least one portion of said liquid phase (9, 20) in said transferring zone (15) in order to detach from said transferring surface (3) said granular material (12, 12b, 12c, 12d) and applying the latter on said receiving surface (13).

Description

technical field [0001] The present invention relates to a system and apparatus for transferring granular material onto a surface to be decorated, in particular for obtaining a decoration on tiles, optionally according to a pattern controlled in real time by computerized means decorate. Background technique [0002] Decorating techniques are known in which the relevant finishing material is supplied to a transfer surface which is moved along a circular path and which then transfers the finishing material to the surface to be decorated. A major difference in many practical applications is the manner in which the decorating material is associated with the transfer surface and the manner in which the decorating material is transferred to the surface being decorated. The latter stage is produced in contact by means of adhesion towards the surface to be decorated, or without contact with the aid of other forces. [0003] Examples of transfer by contact are disclosed in EP530627,...
