Abstract
A sheet deflector for noise reduction in multi-stage folding machines having first and second folding rollers (1,3) with a clearance space (5) between them, with said space (5) being in the path of a sheet (8) to be folded, comprising a sheet deflector (4) having a curved guide surface (20) for deflecting the sheet, at least one slot-shaped opening in the sheet deflector (4) extending toward the bottom of said curved guide surface (20) and extending towards an intake opening (7) between a third folding roller (2) and the second folding roller (3) and a blade-shaped slide (12) which can be horizontally moved out of said slot-shaped opening towards the intake roller opening (7) when the sheet deflector (4) is inserted between said first and second rollers (1,3), whereby the blade-shaped slide (12) is adapted to guide the sheet so that it is folded exactly and faultlessly with very little noise into the bite between first and second rollers (1,3).
