<p>Method and machine for the production of metallic frames for innerspring mattresses with the simultaneous clipping of the two free ends (10a, 10b) (drawing 10). The method is characterized by the principle that the one free end is secured in a gripper (9) (drawing 2 and drawing 5) which is sliding on an arm (7) (drawing 1) thus can follow the straight development of the wire as well as the frames bends (drawing 1, drawing 7). On completion of the last side and angle the free end of the frame is guided from the gripper and the arm in the clipping mechanism (drawing 6) where automatically all the clipping phases are taking place.</p> |
