Pneumatic paper folders are preferable for folding glossy paper. Friction-feed paper folders do not work well with glossy paper as the friction wheel slips on the paper's surface. Most paper folders push paper into the machine by use of a friction wheel this grabs paper using friction. Both usually have fine tuning knobs for precise adjustments. Higher-end paper folders will electronically adjust the folding plates for added precision and convenience. Įntry-level paper folders require that the folding plates be adjusted manually, with fold settings specified on the folding plates. More folds can be accomplished by the use of a 16-page and 32-page unit. Right angle folds require the paper to rotate 90 degrees also known as an 8-page or a right angle. Most paper folders allow for a wide range of fold types. The fold type in a buckle folder is set by adjusting folding plates. Other commonly used folds include a half fold, fold-out, double parallel fold, gate (brochure) fold, and right angle fold. These machines are typically used for creating letter folds (C Folds) and accordion folds (Z Folds). Ideally, knife folding is used with thick paper, for "cross folds" (commonly employed for maps and also known as a "French fold") or if the paper has been stitched during the folding process stitched sheets can ruin high friction rollers.įolding machines exclusively used for folding paper are commonly referred to as paper folders. This knife is not sharp enough to cut through the paper and simply strikes and creases the paper along the line where the fold is required. A knife folder works by striking the paper with a knife between two rollers.
