ABSTRACT:
To accommodate a press tooling carrier without interference, a control arm straight guide having at least one drive, e.g., having motor angular gears (worm gears), cardan shaft or the like is provided. A control arm straight guide permits a very shallow position of the joints in the completely assembled state. A hydraulic cylinder may be used to support startup of the motor, i.e., to move the control arm straight guide out of its bottom dead center position.
