  • Method of bending frame material for the production of compound plates, particularly compound glass panes
    Patent number: 4462237
    Abstract: In producing compound plates, such as compound glass panes, two individual plates are held in opposed spaced parallel relation with a frame located between them and extending along the edges of the plates so that the frame connects the plates together. In assembling the compound plates, the frame is formed by removing a flat strip from a supply source and conveying it to a bending station. While the strip is moved to the bending station or in the bending station a number of miter cuts are formed spaced apart in the long direction of the strip so that the miter cuts separate the strip into connected subsections. The miter cuts are located to correspond to the intersecting edges of the plates. The strip is bent or folded along lines extending in its long direction into a hollow section. Subsequently, the hollow section is formed into a frame by bending the connected subsections at the miter cuts.
