PROCESSO DESTINADO AO FABRICO DE REGUAS DE PERFIL OCO CURVADAS

摘要

In a process for manufacturing bent hollow profiles(1) the profile is bent and then filed with plastic(7) on both sides of the bending point to strengthen the bent area. A more specific process involves clamping the strip(1) in a bending device; heating the bending point; bending the strip and injecting plastic(7) into the hollow chamber at the bending point and to both sides of this. A spacer frame for multi-layer glazing units made by the process comprises a thermoplastic plastic frame(1), preferably with glass reinforcement and the outer side(2) of the frame has a metal foil bonded to it..
