A transfer system, particularly for the transfer of workpieces in multi-station presses (1) consists of several, transfer modules (14 to 19) which each have a workpiece, holding device (28) which is carried by at least one lever mechanism (23). Each lever mechanism transmits the adjusting movement of two mutually independent drives (39 44) to the, workpiece holding device (28). One of the drives (39 44) is, disposed in a stationary manner and the other is moved by the, drive disposed in a stationary manner. This basic principle opens up many design possibilities.

Why it's free to use
- Filed November 9, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 9, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 9, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
