Abstract
Apparatus for cutting a continuously fed web into sheets and for vertically stacking such sheets. The apparatus receives the web between a pair of cutting knives, one of which is periodically rotatable by a motor periodically connected thereto by a pulse fed electrical clutch, and the resulting sheets are conveyed to a vertical stacker by a plurality of laterally spaced conveyor belts driven by the motor. The stacker has a pair of sheet receiving uprights adjustable toward and away from each other and which are mounted on an adjustable stop for engaging the leading edges of the sheets. The stop and the uprights are adjustable in angle with respect to the vertical. A roller below the stack has either crown portions beneath the belt or non-circular portions between pairs of belts to urge the sheets into the stack. Stripping fingers are between pairs of belts for removing the sheets from the belts. To prevent throwing of the sheets, a hold-down roller engages the web adjacent to where it is cut.
