Medalist 870
A Floor Model Air-Feed Paper Folder by Challenge

The Challenge Medalist 870 is designed for versatility and control. This heavy-duty paper folder handles stock from 4˝ x 6˝ to 14˝ x 20˝, including coated paper. Combination steel/rubber rollers and roller calipers deliver the tightest folds and offer superior control, especially on slick stocks. Air for lift and separation is produced by the regenerative blower; suction is created by the vacuum pump. This provides impressive sheet control for a wide range of stocks. The Medalist folds up to 30,000 81⁄2˝ x 11˝ sheets per hour, with mark-free output. On the feeder, a fully adjustable metallic sheet separator helps eliminate double feeds. During folding, precision roller calipers hold roller gap based on paper thickness. At the delivery, a unique jam detector system stops the feeder before problems become significant. A flip-up swing deflector lets stock bypass the fold plate. The feed table swings up for easy access to the lower fold plate. Perfing and scoring shafts are very accessible, for fast changes. The control panel has a built-in total counter and is accessible from either side. For even greater operator convenience, an extended delivery option is available. The Medalist is built to last, and requires minimal maintenance.
