<p>The invention relates to a device for presealing a document onto a plastic web (sheet). It comprises at least one first roller (3) around which the document rolls from a first given point (T1) in the space, this point being tangent to the roller (3), and means (4) for heating the plastic web (2) at a second point (T2), tangent to the roller, where the plastic web (2) is in contact with the document, this tangent point (T2) making a constant angle ( alpha ) with the given point (T1) in the space, the document being presealed by the heating of the plastic web at this second tangent point (T2). Application: Presealing, onto a plastic web, of documents intended to be laminated industrially. <IMAGE></p> |
