Thin steel foil strips - in which is fixed to carrier by bonding on reinforcing folded over parts

摘要

Double glazing may have between the two panes of glass a set of light guiding foils (6,7) with a mirror top (8) which has the shape of a paraboloid and is folded at the edges (24,25) and continues in a section (9) and another paraboloidal section (10). The joint to the carrier wire (21) at the points (17,18) with the recesses (22,23) is done by welding, soldering or cyano-acrylate or loctite (RTM) bonding. The preferred material for the foils is rolled steel strip 0.2-0.4 mm. ADVANTAGE - This requires no spacers to produce any positioning. The folds reinforce the strip just where required.
