The Martin Yale 959AF AutoFolder now features individual vacuum and air pumps for more efficient feeding and lower operating costs. New rubber folding rollers are resistant to the chemicals in carbonless papers. And a dual-surface sheet detector effectively doubles feeding life. Coated or printed stock feeds effortlessly through the 959AF at up to 18,000 sheets per hour. Bottom feeding means you never have to stop the machine to reload or reverse pre-numbered sheets. Make single, letter, accordion (Z), double-parallel, and other folds in sheet sizes up to 14" by 18". French, baronial, and variations can be made in two passes through the 959AF. Ease of setup and operation are ensured with an easy-to-use fold chart and clear, understandable machine controls. Vacuum and air flow can be adjusted to suit virtually any feeding condition and the 959AF's variable speed control allows custom-tailoring of the feed speed. The 959AF can also slit, score, or perforate, separately or during folding.
