Definitions

  • the present invention relates to a method and processing unit for producing sheets for decorating ceramic articles.
  • One method currently used to decorate ceramic articles employs sheets normally made of paper or plastic material, and on one face of which the decoration to be produced on the ceramic article is reproduced by hand using as colouring substances a mixture of oil-diluted ceramic oxides.
  • the sheet is applied to the plain ceramic article, and the whole is baked, so that the sheet material is either burned or absorbed, leaving the decoration in relief on the ceramic article.
  • a method of producing sheets for decorating ceramic articles comprising a colouring step, in which a strip of sheet material is run beneath a number of colouring members for depositing colouring substances on said strip; and a cutting step, in which said strip is cut along a cutting line to define said sheets; said colouring step and said cutting step being performed automatically.
  • the colouring step comprises a drying operation, in which the colouring substances deposited on the strip by the colouring members are dried by a UV source.
  • a processing unit for producing sheets for decorating ceramic articles said unit being characterized by comprising feed means for feeding a strip of sheet material; colour-depositing means for depositing colouring substances on a surface of said strip; and cutting means for cutting a number of said sheets off said strip.
  • the unit comprises drying means located downstream from said colour-depositing means.
  • the method according to the present invention therefore provides for producing sheets for decorating ceramic articles quickly and efficiently, by the colouring and cutting steps being performed fully automatically, and so involving very little time and labour.
  • Number 1 in Figure 1 indicates as a whole a processing unit for producing sheets for decorating ceramic articles.
  • Unit 1 comprises a strip 2 of paper or plastic film sheet material wound about two rollers 3, one of which is powered to feed strip 2 in a direction z along a work surface 4; and suction means 13, shown schematically in Figure 1, for ensuring strip 2 adheres correctly to work surface 4 by means of a number of holes (not shown) formed in work surface 4.
  • Unit 1 comprises a colour-depositing station 5, and a cutting station 6.
  • Colour-depositing station 5 comprises a number of members 7 for transferring colouring substances onto a given portion 8 ( Figure 2) of strip 2.
  • portion 8 of strip 2 receives different colouring substances in sequence from corresponding members 7, so that, on leaving colour-depositing station 5, portion 8 bears a finished decoration.
  • members 7 are defined by known rollers having a cylindrical outer surface, in which dead cavities are formed containing a given amount of colouring substance, which is transferred to portion 8 by direct contact by rolling the cylindrical surface over strip 2 travelling through colour-depositing station 5.
  • Colour-depositing station 5 comprises a number of UV lamps 9, each located downstream from a respective member 7 in the feed direction of strip 2, and which are required to dry the deposited colour, which is defined by ceramic oxides diluted with UV-dry oils.
  • Cutting station 6 comprises at least one cutting device 10, shown schematically in Figure 1, for cutting strip 2 along a cutting line 11, shown by the dash line in Figure 2, to detach from strip 2 individual sheets 12 of appropriate size, which are later applied to ceramic articles in known manner.
  • the method and processing unit according to the invention provide for producing sheets for decorating ceramic articles quickly and efficiently.
  • the colouring step and cutting step need not necessarily form part of the same production line, i.e. once the colour is deposited, the strip of sheet material may be rewound and cut later.
