Architectural glass percent of the world's flat glass is produced by the float glass process invented in the 1950s by Sir Alastair Pilkington of Pilkington Glass, in which molten glass is poured onto one end of a molten tin bath. The glass floats on the tin, and levels out as it spreads along the bath, giving a smooth face to both sides. The glass cools and slowly solidifies as it travels over the molten tin and leaves the tin bath in a continuous ribbon. The glass is then annealed by cooling in an oven called a lehr. The finished product has near-perfect
Heated roll laminator laminators are used to apply varying thicknesses of lamination film onto substrates such as paper or fabrics. The main advantage to the use of heated roll laminators is that of speed. Heated laminators use heated rollers or heated shoes to melt the glue which is applied to lamination film. The process of heating the glue prior to applying the film to a substrate allows for a faster application of the film. The laminates and adhesives used are generally cheaper to manufacture than cold roll laminates, often as much as half the cost depending on the comparison made. As the materials
