Abstract
In a method for the plastification of documents punched out of a sheet, with a plastic cover being fixed to a document, at least two first reference markers are made on the cover, the positions of the first reference markers being defined beforehand with respect to the punch-out line of the document. The position of the punch-out line of the unit constituted by the document and the cover being defined beforehand with respect to at least two reference markers, the unit is punched out when the first and second reference markers coincide. Application to the plastification of all printed documents.
Claims5
A method for the plastification of a document punched out of a sheet by a first punch and its associated die along a first punch-out line, comprising the steps of:
- positioning the document between the first punch and its associated matrix;
- punching out the document by passing the first punch through its die, a first plastic cover being in contact with the die to receive the punched out document at the outlet of the die;
- moving auxiliary punches towards the first plastic cover simultaneously with the first punch to make at least two holes forming first reference markers in the first plastic cover, the position of the auxiliary punches being determined in a plane perpendicular to the direction of movement of the first punch;
- fixing a second plastic cover to the face of the document opposite the first plastic cover, but not covering the first reference markers made on the first plastic cover;
- positioning a second punch-out line of the unit constituted by the document and the first and second plastic covers having been defined beforehand in relation to at least two pads;
- punching the unit out when the pads are engaged in the holes.
