发明名称 Foil transfer apparatus
摘要 Colored or metallic foil is applied to toner printed onto a substrate, such as paper, in a high speed, versatile manner, using a rotating impression cylinder, and a rotating transfer cylinder having circumferentially spaced heated raised portions. The toner, which preferably includes a thermoplastic component, is applied to the paper with any suitable printer, such as a computer controlled MIDAX (ion deposition) print engine. The toner may be heated by an infra red heater just before the paper is fed to the nip between the impression and transfer cylinders. A foil strip having an adhesive layer facing outwardly, a foil layer, and a release coating on a backing, is also fed to the nip, and the backing taken up downstream of the nip. Heat and pressure applied at the nip transfer the adhesive and foil from the foil strip to the tacky toner, producing the desired foil printed paper, which then may be further processed.
