Abstract (en)
[origin: US5136871A] During the bending of a hollow profile strip (53) into a spacer frame for insulating glass panes, the hollow profile strip (53) is advanced, by a gripper (52) displaceable in the feeding direction of the hollow profile strip (53) by predetermined distances, to such an extent that the location of the hollow profile strip (53) to be bent in a particular case is aligned with respect to a bending abutment (20). During the bending processes, performed with a bending lever (62), the hollow profile strip (53) is retained by the jaws (3, 4) of the bending head, and the gripper (52) moves back into its starting position. After the final advancement of the hollow profile strip (53), the latter is severed from the introduced hollow profile strip (53) and only then is the final bending step executed. The hollow profile strip (53) is constantly retained during the production of the spacer frame, either by the gripper (52) or by the jaws (3, 4) of the bending head.
