APPARATUS FOR HANDLING FLEXIBLE SHEET MATERIAL OF DIFFERENT SIZES Abstract of the Disclosure A low inertia rotary drum supports sheets of paper of different sizes for transport and processing. The drum has a plurality of leading edge ports formed in its surface along the length of the drum. A vacuum is selectively applied to one or more of the ports in accordance with the dimension of the paper in the direction of the length of the drum. The drum has a plurality of sets of trailing edge ports formed in its surface with each of the sets being disposed a predetermined arcuate distance from the set of leading edge ports in accordance with the other dimension of the paper. Each set of trailing edge ports has the ports arranged longitudinally along the drum and parallel to the set of leading edge ports. Only one set of trailing edge ports extends for the same length as the set of the leading edge ports. One of the sets of the trailing edge ports has a vacuum applied thereto with the same number of ports of the trailing edge set having the vacuum applied thereto as the number of the leading edge ports.
