Definitions

  • a vertically closing gripper with a controlled gripper shaft is known from DE-C-2 030 040.
  • a disadvantage is the frictional control of the gripper shaft relative to the fulcrum of a control lever by means of a guide on a control cam.
  • the additional control effort leads to an increase in the inertial forces of the system vibrating with a large radius of inertia and thus to a reduction in the performance of the printing press.
  • the control cam is heavily soiled, it is no longer possible to guide the second, vertical movement phase exactly.
