Abstract: Disclosed are a method and an apparatus for producing a folded sheet, the sheet being fed using a feeding mechanism, being aligned using an aligning device, and being folded using a folding device. The aim of the invention is to simplify production, render the production process more flexible, and reduce costs. Furthermore, an alternative apparatus should allow the production costs to be reduced by improving the quality. In the disclosed method, said aim is achieved by positioning the sheet at an angle from the direction of travel during the feeding process, aligning the sheet that has been positioned at an angle, and transferring the aligned sheet into a folding device to produce at least one fold that extends at an angle to the edges of the sheet. In a first embodiment, said aim is also achieved by an apparatus in which the folding device is a buckle folding unit, the shape of the first buckle of which is adapted to the edges of the sheet that are positioned at an angle.
