ABSTRACT:
A curved corner bent from a hollow-profile construction to form a spacer frame of an insulating glazing, where an opening is provided in the inner wall and in the side walls of the hollow-profile construction in the corner zone, so that a free transverse edge on one side of the opening clamps over a free end portion on an opposite side of the opening when the hollow-profile construction is bent at a right angle to form the curved corner, and a process for the production of the corner, in which the opening is a rectangular cut-out into the inner wall and U-shaped cut-outs cut into the side walls, where the side walls are braced during the bending in such a way that the free transverse edge is guided onto the free end portion to provide flat side surfaces on the curved corner after the bending thereof.
