Abstract
Rods are supported on the drive shaft by self-aligning roller bearings such to be able to pendulate. The rods are pivotally mounted to the ram by ball-and-socket joints. At the area of the ball-and-socket joints the ram is guided by upper ram guides. These feature a degree of freedom for a movement in a direction of the web advancing direction of a web to be worked upon. Therefore, the upper tools remain aligned with the lower tools when an eccentric force acts onto the ram.
