Abstract:
A device for bending hollow section strips toward an inside wall of the hollow section strips to produce spacer frames for insulating glass panes, comprising:jaws (14, 15) positioned along side walls of the hollow section strip (2); a bending lever (8) pivotable about an axis; a bending cheek (7) attached to the bending lever and positioned along an outside wall of the hollow section strip (2) to apply a bending force to the hollow section strip; a pivotable bending block (5) having a rounded front end, positioned along the inside wall of the hollow section strip and pivotable about the axis of the bending lever, independent of the bending lever, so that the bending block is initially positioned against a fixed portion of the hollow section strip prior to application of the bending force, and so that the bending block is pivoted from the initial position to a bending position against a portion of the hollow section strip to which the bending force is applied, opposite the bending cheek, the bending block having a flattened portion that is aligned in the initial position of the bending block (5) to be parallel to the hollow section strip (2) and placed against the hollow section strip (2).
