Definitions

  • ABSTRACT A method for decorating ware comprising applying a transfer or print to a portion of the surface of the ware to be decorated, immersing the ware in a mass of particulate treatment media, and vibrating the ware and media whereby the latter act on the print in a manner effective to transfer the desired design or decoration to the surface of the ware.
  • the invention provides a method for decorating ware comprising applying a transfer or print to a portion of the surface of the ware to be decorated, immersing the ware in a mass of particulate treatment media, and vibrating the ware and media whereby the latter act on the print in a manner effective to transfer the desired design or decoration to the surface of the ware.
  • the vibratory movement is a compound vibratory movement incorporating both vertical and horizontal components.
  • Such movement may be effected in a treatment chamber adapted to be vibrated in a generally horizontal plane but resiliently mounted to introduce an up and down movement.
  • the treatment chamber is of annular shape in plan such that when the charge of ware and media is subjected to a compound vibratory movement of the kind described the charge is constrained to circulate around the treatment chamber.
  • FIG. 1 is a sectional elevation through one form of vibratory apparatus in which the process of the invention may be carried out; and I FIG. 2 illustrates a preferred form of media.
  • the apparatus illustrated comprises a treatment chamber or bowl 5 of annular shape in plan and having a bottom 6 of arcuate cross-section and upstanding parallel side walls.
  • the internal surfaces of the bowl are lined with a resilient material such as rubber in order to prevent damage to the ware.
  • the bowl is resiliently mounted on a base unit 10 by an annular series of coil springs 11.
  • a cylindrical housing 12 depends from the central region of the bowl and houses a motor 13.
  • the motor shaft is vertical, projects from the motor casing at both ends and is fitted with eccentric weights l4 and 15. These are preferably relatively angularly adjustable to enable variation of the movement imparted to the bowl by the motor. When the motor is rotated a vibratory movement is imparted to the bowl and an up and down component is superimposed on this movement due to the resilient mounting of the bowl on the base structure.
  • the bowl is filled with discreet particulate media, for example, of the type shown in FIG. 2,. and ware to be decorated is immersed in the media.
  • the ware Prior to this the ware has applied to those surface portions to be decorated, prints or ceramic transfers of known kind which adhere to the surface of the ware and require to be subjected to a rubbing action to transfer the design onto the surface of the ware.
  • the motor Following insertion of the pieces of ware into the media the motor is started and the mass of media and ware is subjected to a compound vibratory movement containing both vertical and horizontal components. The nature of this movement is such that the media are caused to impinge on the surfaces of the ware and effect the necessary rubbing action required to transfer the colouring matter on to the ware.
  • the treatment time required to effect satisfactory transfer may be found by experiment and will vary in accordance with a number of factors including the characteristics of the design and the size and shape of the ware.
  • the nature of the vibratory movement may be altered by effecting relative angular adjustment of the eccentric weights.
  • media of the shape shown in FIG. 2 and composed of zircon While it is believed that various types of media may be employed in carrying out the process, particularly satisfactory results have been achieved using media of the shape shown in FIG. 2 and composed of zircon. It will be seen by reference to FIG. 2 that the media have part-spherical ends 20 interconnected by a generally cylindrical centre portion 21. It is thought that these may produce two different actions on the ware, the ends serving to effect a hammering action and the central portions a rubbing action. It is desirable in order to produce a sufficient force on the surface of the workpieces that the media should be relatively dense and media formed from zircon meet this requirement, though other dense materials could be utilised.
  • the ware is removed and the carrier paper is then detached by wetting, leaving the design on the surface of the ware.
  • the ware may be removed from the machine by hand after stopping the machine or removal of the ware and separation of the ware from the media may be effected automatically using any of a number of techniques known for this purpose. During processing the ware may move round the bowl only once or more than once as necessary.
  • Tests indicate that the process of the present invention effects transfer of decoration to ware more uniformly and with less flaws than conventional techniques involving hand rubbing. Moreover considerably less labour is involved utilising techniques according to the invention and it is envisaged that a greater throughput of products with a higher quality of decoration can be achieved compared with conventional techniques.
  • a further advantage arising from the invention is that the media are able to penetrate to areas relatively inaccessible to manual operators, such as around cup handles and in the interior of cups, though the invention is of course applicable to much simpler shapes and to a large variety of types and sizes of ceramic products.
  • the method of the invention could also be used to apply decoration and a backstamp simultaneously.
  • a further advantage resides in the fact that no mechanical or other types of adjustments are necessary for different shapes or sizes of ware. The size of the ware which can be processed is limited only by the size and capacity of the machine and various different sizes of machine can be made available. 7
