Abstract: An inkjet printing machine on slabs that includes a support for supporting a slab; a locking and centring group configured to contact the slab temporarily locking and centring it on the support; and a printing device provided with at least one inkjet printing head that is mobile with respect to the support along a sliding direction and spaced from it, wherein the printing head is configured to release a decoration on a surface of the slab resting on the support.

Abstract: Cleaning machine (20) of glass articles (G), comprising: a support (21) for supporting a glass article (G); and a heating device (22, 25) located in the vicinity of the support (21), at a distance therefrom, and configured to emit a heat flow (F, H) in the direction of a surface (G1) of the glass article (G) supported by the support (21).

Abstract: A method for controlling an inkjet printing machine on slabs, the printing machine including a support for a slab, and a printing device moveable above the support along a sliding direction and spaced apart from it. The method includes determining a layered decoration to be made with the printing device on the surface of the slab, the layered decoration being formed from the juxtaposition of a plurality of layers of monochromatic decoration, setting an activation sequence of a printing group of the printing device during the sliding of the printing device along the sliding direction as a function of the determined layered decoration, making the printing device slide along the sliding direction on the slab resting on the support, activating the printing group during the sliding of the printing device along the sliding direction based on the set activation sequence and on a predetermined mutual position of the printing group along the direction of mutually adjacent arrangement.

Abstract: An inkjet printing machine (10) on slabs (L) that comprises: a support (20) for supporting a slab (L); a locking and centring group (40) configured to contact the slab (L) temporarily locking and centring it on the support (20); and a printing device (30) provided with at least one inkjet printing head (31) that is mobile with respect to the support (20) along a sliding direction (D) and spaced from it, wherein the printing head (31) is configured to release a decoration on a surface (L1) of the slab (L) resting on the support (20).

Abstract: A kiln (10) for annealing glass slabs, which comprises a plurality of heating chambers (20) that are reciprocally superposed and independent, each heating chamber (20) being provided with: at least an access mouth (24, 25) for passage of at least a glass slab (L), a motorized roller plane (30) on which the glass slab (L) rests and moves, heating means (40) suitable for heating the glass slab (L) located in the heating chamber (20) and cooling means (50) suitable for commanding controlled cooling of the heating chamber (20).

Abstract: A roller cleaning device, in particular for roller kilns specifically destined for performing heat treatments of glass sheets in which the glass sheets rest directly on the rollers, characterized in that it comprises: a cleaning element (2), predisposed to enter into contact with a surface of at least a roller (100) and to clean the surface; motor means (30,31), predisposed to activate the cleaning element (2) to slide at least along a longitudinal direction (x) of the roller (100).
