ABSTRACT:
An apparatus for bending hollow profile strips (1) into spacer frames for insulating glass planes includes a clamp for the hollow profile strip, which clamp can be brought into contact with the lateral surfaces of the hollow profile strip (1), an abutment (20), about which the hollow profile strip (1) is bent, and a pivotable bending lever (50). The abutment (20) is exchangeably attached to a support (21) and can be moved into and out of its operative position by pivoting the support (21) about an axis perpendicular to the plane of symmetry of the clamp (2) and by shifting the support (21) perpendicularly to the plane of symmetry of the clamp (2).
