Abstract
The invention relates to a method for producing a corner of a frame-type spacer for insulating glass panels by (a) making a metal hollow profile rod available, which rod has an outer wall, two parallel flanks, and an inner wall, (b) indenting the inner wall and the two flanks in the position of the hollow profile rod where the corner is supposed to be formed, and (c) bending the hollow profile rod by a defined angle.
Claims42
A method for producing a corner of a frame-shaped spacer for insulating glass panes, said method comprising:
- (a) preparing a hollow profile rod, which comprises an outside wall, two parallel flanks that are parallel to each other, and an inside wall that is parallel to the outside wall, wherein the two parallel flanks adjoin the outside and inside walls;
- (b) impressing each of the two parallel flanks at a corner formation site;
- and
- (c) bending the hollow profile rod about the inside wall at the corner formation site to a specified angle;
- the method further including the step of impressing the inside wall of the hollow profile rod at a corner formation site before bending the hollow profile rod about the inside wall.
