Abstract
A method of manufacturing a retro-reflective shell having a curved or irregular surface for reflecting light in all directions from a laminated product, comprising a substantially flat sheet of a plastic material and a reflective layer on at least one side of said flat sheet plastic material. The reflective layer comprises a transparent adhesive substance and transparent glass or plastic pearls with a diameter between 0.01 and 0.05 mm. The substance adheres to the flat sheet plastic material, to form the laminated product. The product is heated to a thermo-vacuum-forming temperature, whereupon the product is vacuum-formed on a mould having the desired curved or irregular surface shape, in order to form a shell.
Claims19
A method of manufacturing a retro-reflective shell having a curved or irregular surface for reflecting light in all directions, the method comprising the steps of:
- providing a substantially flat sheet of a plastic material;
- applying a reflective layer on at least one side of said flat sheet plastic material by depositing a transparent adhesive substance and at least one of glass pearls and plastic pearls having a diameter between 0.01 and 0.05 mm onto said flat sheet plastic material forming a laminated product;
- hardening the laminated product by at least one of heat and radiation;
- heating said hardened laminated product to a thermo-vacuum-forming temperature;
- contacting the plastic material of the heated laminated product to a mould having at least one of a curved shape and an irregular surface shape;
- forming the retro-reflective shell by thermo-vacuum-forming said laminated product on the mould.
