The present disclosure relates to sheet deceleration apparatus and methods for decelerating a sheet of material for use in a sheet stacking or other application. The deceleration apparatus includes a pair of rotatable rollers (26, 28), being rotatable about first and second axes, the rollers positioned on opposite sides of the travel path. At least one of the rollers is moveable relative to the other to nip the sheet between the rollers to reduce the travel speed of the sheet (15). A vacuum conveyor (60) is further provided along the travel path subsequent the pair of rollers to control delivery of the sheet to a stacking hopper(ll). A third rotatable roller(72), or similar apparatus, may be included in some embodiments, for pushing the sheet of material away from the vacuum conveyor at the appropriate time. |
