  • Patent number: 5975280
    Abstract: A device for transporting flat products to further processing units is provided which includes a track 4 forming a continuous loop, a plurality of gripper elements 1 and a driving module 99. The gripper elements 1 are arranged on the track 4, and include a gripper 2 for seizing a flat product 11 from a first device and releasing the flat product to a second device 13. Each gripper element 1 moves independently from each other gripper element 1 along at least a portion of the track 4. Each gripper element is selectively engaged by the driving module 99 for movement along the track. The driving module 99 may include, for example, a drive unit 9 for driving the gripper elements in a side-by-side configuration without pitch; an extended pitch driving unit 7 for driving the gripper elements at a defined pitch; an acceleration unit 6 for accelerating the gripper elements to the defined pitch; and/or a diverting unit 32 for diverting selected gripper elements to an alternate track.
