Abstract (en)
[origin: US4660271A] In a process of manufacturing a spacer frame for a perimeter-bonded insulating glass pane, a metal tubular bar is filled with a granular desiccant and is subsequently bent in each corner-forming portion about an axis which is at right angles to two parallel cheeks of the bar. The two cheeks are drilled through in each of said corner-forming portions to form two bores and a small quantity of the granular desiccant is removed from each of said corner-forming portions through at least one of said bores therein before said corner-forming portion is bent.
