Paper processing device has paper inversion devices with elements curved in direction perpendicular to paper motion direction with radius of curvature decreasing in motion direction

摘要

The device has an arrangement for turning paper objects (12,16,18) over with a surface element (14) curved in a direction perpendicular to the direction of paper motion with a radius of curvature decreasing in the direction of paper motion. Two or more paper inversion devices can be arranged in the direction of paper motion.
