  • Patent number: 5383348
    Abstract: In a press, an individual press, a multistage press, a multistand press and similar forming facilities, transfer devices are provided for the transport of sheet metal parts in the machining stages. These transfer devices have guide strips which can be lifted and lowered in vertical guides on the press stands via adjusting devices. In each guide strip, toothed belts are arranged which are guided on deflecting rollers. The moving drive in the horizontal direction takes place from a motor-transmission device. As a result, a reduction of the mass of the movable structural members of the transfer device is achieved while the construction of the transfer device is modular.
