<p>PCT No. PCT/CH88/00027 Sec. 371 Date Oct. 3, 1988 Sec. 102(e) Date Oct. 3, 1988 PCT Filed Feb. 3, 1988 PCT Pub. No. WO88/05724 PCT Pub. Date Aug. 11, 1988.To drive two toggle lever (29,29') of a press, in particular a high frequency cutting press with at least 400 strokes per minute, two separate but mutually synchronized drives (101,101') are provided to ensure a uniform, non-wobbling motion of the tool carrier (5). The drives (101, 101') can be rotary or linear drives and are used to drive the toggle levers (29, 29') during at least part of their motion. The energy storage (200) ensures a low energy consumption, since it stores the braking energy and supplies it again to the drive during acceleration.</p> |
