The FD 396 is combined with the FD 390 air feed machine to create a 2 machine system that can perform a right angle or cross fold (fold once in half, then fold again from the side) in one pass.
The Formax FD396 folder is an air feed folding system that can handle very high volume and glossy stock. It is typically used to create a folded brochure, calendar or a self mailer. It will fold the paper the long way in half, and then fold the folded sheet in half or thirds from the side. The first fold is limited to a half fold. The second fold is limited to either a half or letter fold. So for example, you can fold a piece of 11 x 17 inch paper into a piece 8.5 x 3.75 (trifold). or 8.5 x 5.5 inches (half fold).
