Abstract:
A device for supplying glaze in rotary machines for decoration of ceramic tiles, of a type where, on a mobile rest plane on which the tiles are translated in a predetermined direction, the following operate: a matrix-bearing cylinder, mobile in rotation about an axis thereof, which matrix-bearing cylinder is provided with at least an elastically-deformable peripheral part having a smooth external cylindrical surface made of an elastomer material, on which smooth external cylindrical surface a shape is cut and recessed, which shape is a matrix; at least a doctor predisposed for operating in contact with the external surface of the matrix-bearing cylinder; a supply of glaze being contained in a chamber delimited between the at least a doctor and a portion of the external cylindrical surface of the cylinder facing the doctor in a relative zone of contact there-between; wherein it comprises:a guide which is parallel to the doctor, which guide extends for at least an entire length of the at least a doctor and which guide is located superiorly to a part of the at least a doctor which part is destined to come into contact with the external cylindrical surface of the matrix-bearing cylinder; a flexible element which is destined to slide along the guide and to support at least a flexible conduit for supply of glaze, which flexible conduit terminates in a discharge end which is located superiorly to the chamber; the flexible element being partially wound about and partially coupled in rotation on a drive wheel which can rotate in two directions.
