Abstract:
Apparatus for inverting and returning sheets (9) from a printer (1) for large-sized paper, said apparatus comprising an inlet area (11) where the sheet (9) is received from the printer (1), and an outlet area (12) where said sheet (9) is returned to the printer (1), a front edge (60) of the sheets (9) remaining in front during the receiving, inverting and returning movement of said sheets (9), characterised in that the apparatus comprises a frame (16) mountable on the support (2) of the printer, and a guiding slit (18) in the inlet area (11), said guiding slit (18) being defined by a downward surface on an upper guiding wall (13) and an upward surface on a lower guiding wall (17), where said upward surface having a downwardly curving profile extends from the inlet area (11) to a clamping slit (22) between a first pair of roller means (23, 24), whereby the lower guiding wall (17) is tiltable and adapted to be moved about a substantially horizontal axis from a sheet-supporting and -forming position in which the guiding slit (18) is formed and into a downwardly extending sheet-releasing position, that in use the outlet area (12) is placed over and adjacent the inlet area (11), and that the frame carries a second pair of roller means (33, 24) adapted to receive the sheet from the first pair of roller means (23, 24) and to guide the sheet (9) through the outlet area (12) and back to the printer (1).
