Printing polymer interlayer adhesive material of laminated glazing in windshield of car, comprises contacting relief surface called shot, polymer or photopolymer and inked material, with interlayer adhesive polymeric material

摘要

The method comprises contacting a relief surface called shot, polymer or photopolymer and inked material, or a metallic etched surface and inked material, with an interlayer adhesive polymeric material. The relief surface or the etched surface is axisymmetric about an axis parallel to the conveyor belt of the polymer material, and perpendicular to the advancement direction of the material. The relief surface or the engraved surface is located in a cylinder parallel to the axis of the conveyor belt of the polymeric material, and perpendicular to the direction of travel of the material. The method comprises contacting a relief surface called shot, polymer or photopolymer and inked material, or a metallic etched surface and inked material, with an interlayer adhesive polymeric material. The relief surface or the etched surface is axisymmetric about an axis parallel to the conveyor belt of the polymer material, and perpendicular to the advancement direction of the material. The relief surface or the engraved surface is located in a cylinder parallel to the axis of the conveyor belt of the polymeric material, and perpendicular to the direction of travel of the material. The printing step of the polymer interlayer adhesive material is carried out by reel to reel process in a sheet. A set of printing units arranged in series, or around a central drum or stack for printing is same fraction of the polymer material. The inking step of the relief surface, called snapshot, is effected by contact with a gravure cylinder called anilox roller, where cells of the anilox roller are filled with ink by a chambered doctor blade system, a bubbler system, a tray filled with ink, or a spray. The anilox roller has high volume of 2-6 cm 3.m - 2. The ink is water-based or solvent-based ink.
