Abstract: Method for protecting printed data on a varnish area of a transfer film of a heat-transfer machine, including: a varnishing step during which the varnish area and a plastic card advance simultaneously under the thermal head and during which the thermal head heats in order to deposit the varnish on the plastic card, generating a deformation of the transfer film at a text printed on the plastic card; a rewinding step during which the transfer film is rewound in order to position the varnish area upstream of the thermal head, and the plastic card is repositioned upstream of the thermal head; and a defacing step during which the varnish area and the plastic card advance simultaneously under the thermal head and during which the thermal head heats at the level of the text and at the deformation in accordance with a sign scheme making the deformation illegible.

Abstract: A system for separating a bottom plastic card includes a loading roller, on which a first end of the bottom plastic card rests, having a groove extending parallel to the axis of said loading roller. A movable assembly is disposed above the loading roller and includes a base and a loading wheel free to rotate. The base is moveable vertically between a contact position and a separated position. A return means constrains the movable assembly in the contact position. The base has an upstream wall upstream of the loading wheel and the bottom end of which is, in the contact position, at a distance from the loading roller less than the thickness of the bottom plastic card. The groove has an opening and a depth sufficient to enable the bottom plastic card's first end to descend in the groove so its first end passes under the upstream wall's bottom end.
