Definitions

  • the invention relates to tubular decorating means, particularly for decorating ceramic products.
  • the tubular skirt is permanently connected to the end flanges, for example by means of gluing.
  • printing rollers are known for decorating flexo-printing machines of ceramic tiles, comprising a tubular decorating element, externally carved so as to define a decorative pattern to be printed on the tiles.
  • the aforementioned printing rollers must be axially tightened so as to distance from one another the end flanges with which the aforementioned printing rollers are provided. Tightening is rather critical, inasmuch as it may cause the deformation of the decorative pattern and, therefore, negatively affect print quality.
  • Such printing rollers may be subjected to ovalization or to torsional deformation during operation.
  • the printing rollers comprise a support body made of plastic material, for example a polymeric resin, having the form of a hollow cylinder, on the outside of which is provided a tubular body made of elastomeric material, such as silicon, for example.
  • the tubular body is provided with a smooth external surface arranged to interact with a visible face of the ceramic products to be decorated.
  • a plurality of cavities is formed, obtained for example by means of laser beam engraving, which cavities are arranged according to a preset pattern to be impressed on the aforementioned visible face.
  • Opposite ends of the support body are solidly fixed, for example by means of gluing, to flanges suitable for enabling the roller to be mounted on a decorating machine.
  • the above-disclosed printing rollers do not substantially have deformations or ovalizations during use.
  • a further drawback of the aforementioned printing rollers consists of a certain manufacturing complexity due, in particular, to difficulties with which may meet fixing the tubular body to the support body.
  • An object of the invention is to improve the tubular decorating means of the prior art.
  • Another object of the invention is to obtain tubular decorating means having reduced dimensions.
  • a further object of the invention is to obtain tubular decorating means easier to transport.
  • a further object of the invention is to obtain tubular decorating means having great rigidity and being particularly easy to manufacture.
  • roller decorating means for decorating items comprising tubular transferring means arranged to transfer a decorating product to said items, supporting means associated with said tubular transferring means and fixing means arranged to fix said tubular transferring means to said supporting means, said fixing means comprising elastic connecting means arranged to press said tubular transferring means against said supporting means, characterized in that said elastic connecting means comprises lamina means arranged to movably fix said tubular transferring means to said supporting means, said lamina means defining sleeve means that are elastically deformable, said supporting means comprises wall means defining chamber means arranged to receive ends of said tubular transferring means, said lamina means being associable with said supporting means in such a way that said ends are interposed between said lamina means and said wall means.
  • said supporting means comprises a pair of flanges each one of which is suitable for being associated with a respective end of the tubular transferring means.
  • the elastic connecting means comprises a pair of elastic sleeves suitable for being inserted inside the tubular transferring means and for being positioned in such a way that each one of the aforementioned ends of the tubular transferring means is interposed between one of the aforementioned elastic sleeves and a wall delimiting the flange, so as to movably fix the tubular transferring means to the flanges.
  • roller decorating means provided with tubular transferring means that can be separated from the respective supporting means when the roller decorating means has to be stored and/or transported.
  • the tubular transferring means may therefore take on a folded configuration that enables its dimensions to be significantly limited.
  • the flexible supporting means is made of a material that is substantially inextensible and preferably geometrically stable at least in the absence of external forces.
  • the flexible supporting means comprises a plastic laminate.
  • the aforementioned plastic laminate comprises a plurality of through holes.
  • the flexible supporting means is made of a material sufficiently rigid so as to ensure that a regular cylindrical form is maintained when the roller is not subjected to external forces, as occurs for example during handling, storage and during phases of mounting on and dismounting from a decorating machine.
  • roller decorating means 1 comprising sleeve decorating means 2 suitable for transferring a decorating product onto an item to be decorated, for example a ceramic support.
  • the sleeve decorating means 2 can comprise a silkscreen printing screen, or a skirt in elastomeric material, or finally a skirt in elastomeric material inside which a laminar element in a material flexible and substantially inextensible is embedded, as will be better disclosed below.
  • the roller decorating means 1 further comprises a pair of flanges 4 associable with opposite ends 5 of the sleeve decorating means 2 to enable the roller decorating means 1 to be mounted on decorating machines.
  • the roller decorating means 1 further comprises elastic connecting means 6 arranged to movably fix the ends 5 to the flanges 4.
  • the flanges 4 comprise walls 7 defining cylindrical chambers 51 arranged to receive the ends 5.
  • the elastic connecting means 6 comprises a pair of laminas 8 that can be folded in such a way as to form sleeves 10 arranged to press the ends 5 against the walls 7.
  • the laminas 8 may take on a folded mounting configuration, indicated by A, in which they can be positioned in relation to the walls 7, and an extended locking configuration, indicated by B, in which they fix the sleeve decorating means 2 to the flanges 4.
  • an end 5 is inserted inside the cylindrical chamber 51 of the respective flange 4.
  • a lamina 8 is taken into the folded mounting configuration A and inserted inside the sleeve decorating means 2 by an opening 9 obtained in the flange 4.
  • the lamina 8 can be manually maintained by an operator in the folded mounting configuration A.
  • the aforementioned operator then releases the lamina 8, after positioning it, in such a way that the latter takes on the extended locking configuration B.
  • the flange 4 is separated from the sleeve decorating means 2 and lastly the lamina 8 is removed.
  • the sleeve decorating means 2 is provided, at each end 5, with a first groove 11 and with a second groove 12.
  • Each flange 4 is provided, at the wall 7, with a first projecting element 13 and with a second projecting element 14 both arranged to be received respectively in the first groove 11 and in the second groove 12.
  • the first groove 11, the second groove 12, the first projecting element 13 and the second projecting element 14 thus act as fixing promoting means arranged to improve adhesion of sleeve decorating means 2 to the flanges 4.
