The Mark VII AirFeed paper folder offers all of the benefits that come with the friction-fed model but with the added airfeed technology. As an upgrade from the Mark VII folder, this AirFeed model is perfect for sensitive paper stock, including gloss, coated, laser, and copier paper types. Designed for continuous bottom feeding, the vacuum pulls one sheet at a time into the rollers to produce crisp folds. This machine adjusts to the paper thickness to prevent multiple sheet feeding. High speed folding is critical for any office looking to produce thousands of finished documents a day and the Mark VII AirFeed is up to the task. Folding at a rate of up to 35,000 sheets per hour, the Mark VII AirFeed's feed tray holds up to 300 sheets of 20-lb. bond paper. This is a substantial amount and will help reduce the number of times required to refill the feed tray. The Mark VII AirFeed is quite flexible, handling a minimum paper size of 3.5" x 4.24" to a maximum of 14" x 20". A variable speed function allows for ultimate control and the various speed conveyor is independent of the fold rollers. Choose from six different fold types: Letter, Half, Z-Fold, Double-Parallel, Engineering, and Church Fold.
