ABSTRACT OF THE DISCLOSURE The invention relates to a curved corner bent from a spacer frame hollow profile, of an insulating glazing with cut-outs in the inner wall and in the side walls in the corner zone, in which in the corner zone (15) a free transverse edge (15) of a wall (7) grips over a free end zone (14) of a wall (7a) extending at a right angle to the wall (7). The invention relates, further, to a process for the production of the corner, in which a rectangular cut-out is introduced into a wall (7) of a spacer hollow profile (5a), which extends also in partial zones into the side walls and there creates U-shaped cut-outs, that there is then carried out the bending, preferably with bracing of the side walls, in such a way that the free transverse edge (1.5) of a wall (7) is guided onto the wall (7a), in which process it projects over the free transverse edge (15a) of the wall (7a) by the excess (14).
