A gripper-device for a printing machine, comprising a spring gripper-finger connected rigidly to the gripper-shaft, is designed, with the simplest possible configuration, in such a manner that, when the grip is closed, there is practically no displacement of the material to be printed which has been gripped. To this end, the gripper-device is designed in such a manner that the neutral fibres of the spring-section adjoining the tip of the gripper, when designed as an individual spring-rod, run substantially in the plane defined by the longitudinal axis of the gripper-shaft and by the tip of the gripper, and when designed in the form of spring-rods arranged in parallel with, and spaced from each other, run in parallel with this plane. |
