Abstract: On a mobile rest plane on which tiles are translated in a predetermined direction, the following operate: a matrix-bearing cylinder, mobile in rotation about an axis thereof, and at least a doctor predisposed to operate contactingly with an external surface of the cylinder. The apparatus comprises: a vertically-developing frame; a first slide constrained on the vertical frame and slidable vertically with respect thereto; the matrix-bearing cylinder being supported on the first slide, together with organs for supporting the matrix-bearing cylinder and organs for controlling rotation thereof about a rotation axis thereof; a second slide, with at least one doctor being supported thereon, together with organs for supporting the doctor and organs for controlling movements thereof, is constrained on the frame and can slide vertically with respect thereto.

Abstract: On a mobile rest plane, the following operate: a matrix-bearing cylinder, rotatable about an axis thereof, and at least a doctor predisposed to operate contactingly with an external surface of the matrix-bearing cylinder. A supply of glaze is directed into a chamber delimited between the doctor and a portion of external cylindrical surface of the cylinder facing the doctor, at a position in which the doctor and the surface are in contact, via a flexible conduit terminating at a discharge end thereof which is positioned superiorly of the chamber and which is commanded to perform an alternating motion. The flexible conduit is supported by an articulated chain which is commanded to slide axially in two directions along a guide.

Abstract: The machine comprises: a mobile rest plane for tiles on which the tiles transit in a predetermined advancement direction; a decorating apparatus which comprises a plurality of cylinders, located above the mobile rest plane; means for setting the plurality of cylinders in rotation each about an axis thereof, and with a predetermined stagger of one of the plurality of cylinders with respect to others of the plurality of cylinders. The means for setting the plurality of cylinders in rotation employ a mechanical transmission of drive to the plurality of cylinders which comprises a driven gear coaxially and solidly associated to each of the plurality of cylinders. The driven gears are drawn in rotation, with couplings allowing no relative dragging, by a chain and have diameters which are different from diameters of the plurality of cylinders to which they are solidly constrained.
