Abstract
In the case of a sheet-transporting gripper configuration in a sheet-processing machine, e.g. printing machine, it is provided that a low-mass gripper housing contains thin side walls enclosing a gripper shaft such that imaginary extensions of leaf springs provided intersect at a point on a straight line which passes through gripper tips and a gripper-shaft axis. The point of intersection is located on the far side of the gripper-shaft axis, as seen from the gripper tips.
Claims3
An apparatus for transporting sheets in a sheet-processing machine, the apparatus comprising:
- a gripper support;
- a gripper shaft;
- a gripper pivotably mounted on said gripper shaft and having a gripper tip interacting with said gripper support;
- and
- two straight leaf spring sections adjoined to a gripper housing for articulating said gripper tip about said gripper shaft, said leaf spring sections being oriented such that respective straight imaginary extensions of said leaf spring sections intersect at a point on a straight line passing through said gripper tip and a center axis of said gripper shaft, said point being located on a far side of said center axis, as seen from said gripper tip.
