Abstract
The feed table of a paper folder is provided with a downward step at the discharge end of the feed table. The downward step provides a discharge area so that the leading edge of a sheet can be pulled forward and down for a positive feed without wrinkling the leading edge through contact with the feed table. A vacuum wheel engages and holds the paper to effect the feed, and the vacuum wheel has an increased number of holes for a stronger grip. The rear ends of paper guides are movable by screws for carefully controlled skewing of the paper with respect to the feed table.
