Abstract
A folding unit has two folding rollers with a common folding nip. A first insertion slot has a first insertion plane for a selectively insertable buckle plate and is configured so that a buckle plate mouth of the buckle plate is at an inlet side of the folding nip. A second insertion slot has a second insertion plane for a buckle plate. The second insertion plane is inclined with respect to the first insertion plane and the second insertion slot is designed for the buckle plate mouth of the selectively inserted buckle plate to be arranged on the inlet side of the folding nip. Printing substrates with different properties are processed in a high-quality and highly productive manner in a pocket folding process, especially in buckle folding units of industrial folding machines.
