Architectural glass light in industrial factories. Annealed glass is glass without internal stresses caused by heat treatment, i.e., rapid cooling, or by toughening or heat strengthening. Glass becomes annealed if it is heated above a transition point then allowed to cool slowly, without being quenched. Float glass is annealed during the process of manufacture. However, most toughened glass is made from float glass that has been specially heat-treated. Annealed glass breaks into large, jagged shards that can cause serious injury and is considered a hazard in architectural applications. Building codes in many parts of the world restrict the use of annealed glass
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
