  • Apparatus for transporting workpieces in presses
    Patent number: 7448489
    Abstract: A transporting apparatus, in particular a 3-way transfer means, for transfer presses, in the case of which, for horizontal movement, linear drives are attached and actuated such that, along with a compact construction, the linear drives allow the gripper rails to be changed straightforwardly during tool-changing operations.

  • Transport system
    Patent number: 6715981
    Abstract: A transport system provided in particular for large-component transfer presses is distinguished by a design with a low width and, nevertheless, permits large transport steps. By controlling two drives in the direction of rotation in relation to each other, all desired travel curves in one plane can be realized. As a result of the simple construction, a cost-effective solution is achieved for a highly dynamic transport system.
