method and device for bending of hohlprofilleisten to abstandhalterrahmen for insulating glass units.

摘要

When bending a hollow profile strip (53) into a spacer frame for panes of insulating glass, the hollow profile strip (53) is advanced by a gripper (52) displaceable by certain distances in the feed direction of the hollow profile strip (53) to an extent such that the section of the hollow profile strip (53) to be bent in each particular case is aligned relative to a bending abutment (20). During the bending operations, which are carried out with a bending lever (62), the hollow profile strip (53) is held by the jaws (3, 4) of the bending head and the gripper (52) moves back into its starting position. After the last advance of the hollow profile strip (53), it is cut off from the hollow profile strip (53) fed in and only then is the last bending operation carried out. During the production of the spacer frame, the hollow profile strip (53) is held continuously, either by the gripper (52) or by the jaws (3, 4) of the bending head. …IMAGE…
