The 352F paper folder by MBM, the fastest in its category, is a heavy-duty paper folder meant for print shops and other production environments. For extended durability, it is built with non-flexing frames on the side. The double roller, friction feeding allows for a variety of sheets, even carbonless paper. The rollers automatically change for different weights and thickness of paper. Maximum paper weight is 110 lbs, and 300 sheets is the maximum tray capacity. There is quick adjustment for either standard or custom folds, with flexible speed control. This paper folder has a motorized conveyor belt that makes a nice neat stack. There are needle bearings for jobs where precision and dependability are crucial. The 352F provides convenient separation of the sheets from the top of the fanned stack of paper. There is no need for roller pressure settings, because the folder contains polyurethane foam rollers. The production is fast, folding sheets at the speed of 22,000 an hour. Though this MBM paper folder is heavy-duty, it is light and small enough to fit on a table. It is a good match for users looking for speed and the flexibility to conquer more complex folding jobs.
