Abstract
The object of this invention is to transfer, fix and polish images produced by: toner laser printers or inkjet printers, flexographic technology, silkscreen technology, offset technology, printed on reel support (A), on the plastic or metal surface of three-dimensional objects (16), thanks to which it is possible to detach images from the reel support (A) and subsequently transfer them to the surface of said plastic or metal objects (16) by a thermomechanical (1, 10) action.
Claims11
Apparatus for transferring, fixing and polishing images on plastic or metal surfaces of three-dimensional objects characterized by the use of different printing processes on support means such as:
- support reel (A) of the images of a plastic film of polyester or paper with detaching features, for example silicone-coated at least on one side, where this support is printed by electrographic laser printers with digital images with thermoplastic ink in powder, called toner, where this support has a gloss, matt or holographed surface finish to give this feature to the final product;
- or
- support reel (A) of the images of polyester or paper film treated with heat releasing materials, coating by hot transfer, where this support is printed by silkscreen printing, ink jet printing, offset printing or flexographic printing, where this support has a matt, gloss or 3D surface finish that is suitable for transmitting this feature to the final product;
- wherein this apparatus comprises:
- conveying means for said support, with at least one hot fixing roller (10) connected mechanically to at least one generator (1) of blown hot air, known as a melter, and at least one non-heated workpiece holder (11) opposite said hot roller (10), wherein said melter (1) comprises at least one conveying chamber (3) conveying the air that maintains the air hot on the surface of the hot roller (10), which is provided with continuous rotary movement, - at least one mechanical element (13), known as a delayed detachment element provided with translating movement that is integral with or independent of the movement of the hot roller, and is suitable for modifying the path of the film, maintaining the path in contact with the object, after the transfer of the image to give the image a gloss, matt or holographed finish depending on the finish of the support.
Electrographic printing machine for producing the digital images on a non-stick paper or plastic support (A), for example siliconated support on a reel placed in line with the transfer, fixing and polishing apparatus of said images on the objects according to one of the preceding claims.
