Abstract (en)
[origin: US5181412A] Apparatus for bending hollow profiles 3 into spacer frames for insulating glass panes, the hollow profile 3 being advanced by a gripper 2 displaceable along a conveyor 4. The magnitude of the stepwise advance of the hollow profile 3 corresponds to the lengths of the legs of the spacer frame to be made. A pickup 6 on the gripper 2 measures precisely each stepwise advance.
