Sheet-fed rotary printing machine, has retarding device exhibiting circulating gripper arm with claws rotated around rotation axis, where sheet of paper packages are guidable and retardable in guide plate by claws

摘要

The machine has printing units for printing sheet or paper and an arm containing a collecting cylinder (2) and a stacking device, where the sheet or paper is collectable on the collecting cylinder. The sheet or paper is deliverably collected at a retarding device (3) and retarded to the stacking device. The retarding device exhibits a circulating gripper arm (3.1) with claws (3.2) i.e. clamping claws, rotated around a rotation axis, where the sheet of paper packages are guidable and retardable in a guide plate (3.3) i.e. hollow cylinder surface, by the claws.
