An image forming apparatus includes an image forming unit, an input unit configured to receive input of folding unit information specifying either one of a first sheet folding unit and a second sheet folding unit, and a control unit configured to selectively perform a first mode and a second mode based on the folding unit information, the first mode being a mode in which the image forming unit forms the image on the sheet such that an orientation of the image becomes a first direction, the second mode being a mode in which the image forming unit forms the image on the sheet such that the orientation of the image becomes a second direction inverted from the first direction.

An assembly for folding polymeric film for machines for forming pouches and the like includes a fixed frame for supporting a magazine for the polymeric film, an element for folding the film that arrives from the magazine, and at least one heat-sealing device for the stable coupling of juxtaposed portions of the folded film that arrives from the folding element. The folding element is mounted on a carriage, which can translate along a respective guide which is integral with the frame, along the sliding direction of the film, with a speed that is variable in intensity and sign. The at least one heat-sealing device acts on portions folded onto themselves of the film during a temporary stop thereof. The carriage retracts with respect to the sliding direction of the film for the entire duration of the temporary stop step provided for the heat-sealing of the film.
