Abstract
Process for the production of variously decorated artefacts, comprising the steps of: preliminary preparation of the surfaces of the artefact, possible application of preliminary painting cycles or other surface treatments; covering or tight-wrapping up of the artefact with a transfer support bearing the decorations desired, realized from gas-tight thermoformable plastic material such as polyvinyl alcohol; creation of a vacuum between said transfer support and the artefact covered by the same, so that the support adheres to the shape of the artefact; and heating for the transfer of the decoration and the polymerization of the colors.
Claims11
A process for treating artefacts consisting essentially of the following steps in sequence:
- providing an envelop formed from a transfer support consisting essentially of a single layer of material coated with a pattern, wherein said envelope is adapted to receive the artefact;
- sucking air from an open end of said envelope to cause said transfer support to adhere to both sides of said artefact;
- transferring said pattern from said transfer support to both sides of said artefact by heating said artefact and said transfer support and applying pressure to said pattern in contact with said artefact;
- wherein said step of providing said envelope comprises forming said envelope from said transfer support so that said open end is defined by edge portions of said transfer support;
- wherein during said sucking step, said envelope is so arranged as to retain flexibility along its periphery, thereby allowing said pressure to be applied to said pattern directly by said transfer support;
- and wherein said envelop comprises an inner side contacting said object and an outer side contacting an external environment surrounding said envelope.

An apparatus for treating artefacts consisting essentially of:
- enclosing means for enclosing an artefact into an envelope formed from a transfer support consisting essentially of a single layer of material coated with a pattern;
- sucking means for sucking air from an open end of said envelope to cause said transfer support to adhere to said artefact;
- heating means for heating said arteface and said transfer support to transfer said pattern from said transfer support to said artefact;
- pressing means for applying pressure to said pattern in contact with said artefact to transfer said pattern onto said artefact;
- wherein said enclosing means comprises forming means arrange for forming said envelope from said transfer support so that said open end is defined by edge portions of said transfer support;
- wherein said pressing means comprises said transfer support which is provided with a flexible peripheral region arranged so as to allow said pressure to be directly applied by said transfer support to said pattern when air is sucked from said open end;
- and wherein said envelope comprises an inner side contacting said object and an outer side contacting an external environment surrounding said envelope.
