<p>In the process, a laminate of heat-formable material, transparent or coloured-transparent, metallized on one side with silver or aluminium, is continuously unwound from a reel (1) and fed to an embossing cylinder (2) which, on the metallized side of the laminate, forms a structured surface with micro-prisms which give back-reflective properties to the laminate; a device (4) performs a roughening treatment on the structured surface in order to improve adherence of a subsequent layer of protective paint applied by a distributor roller (5); a pair of rollers (7) couples a bi-adhesive film to the laminate. The laminate has high back-reflective properties and also has characteristics of luminosity and colour which satisfy existing road signal standards.</p> |
