for conveying flat articles in dense conveying streams , grippers conveyed one behind the other by conveying elements are used , each gripper holding one of the articles gripped in an edge zone . for increasing the possibilities for changing the orientation of the flat articles during such conveyance , the grippers are attached to the conveying elements by asymmetrically - projecting gripper arms and the grippers are designed to be rotated through 360 ° around the gripper arm axis . the device can be used universally , particularly for held conveyance of printed products and it is very easily adjustable for differing applications .
