Process for placing at least one functional film on at least a portion of one side or both sides of flat or arcuate substrates, film application machine for process execution, and plates

摘要

The deposition of a functional film (5) on at least a part of one or two surfaces of a flat or curved substrates (2) consists of: (a) feeding the substrates one by one into a filming station for them to defile through a film applying assembly (4) containing at least one axis which is perpendicular to the sense of defilement and parallel to the defilement plane and on which is mounted at least one reel of film; (b) feeding the initial section (10) of the film from each reel to be applied and maintained on a surface of the substrate at the chosen location; (c) provoking the unreeling of the reel(s) to apply the film in layers on the defiling substrate; and (d) cutting the film(s) at a chosen moment whilst retaining the new beginning section of the film for it to be applied at the chosen location on the same or a following substrate. An independent claim is also included for a machine for applying a functional film on a substrate by this method.
