Abstract: A machine for cross cutting a material web has a main frame part unitarily formed with a pair of transversely spaced main sides and with at least one main traverse extending transversely between the main sides and a secondary frame part unitarily formed with a pair of transversely spaced secondary sides and with at least one secondary traverse extending transversely between the secondary sides. The main frame part is formed at its sides with a seat on which the respective sides of the secondary frame part fit complementarily with the main and secondary traverses extending parallel to each other. Two blade drums rotatable about respective transversely extending drum axes have ends journaled in the sides at the seat. Fasteners secure the frame parts together at the seat to opposite sides of the drum ends.

Abstract: A device for cross cutting a cardboard web in which, both the blade drums, a sheet transport conveyor accelerates the sheets and then the sheets are positioned to shingle the sheets on a further conveyor. The sheet transport conveyor has a rerouting roller at the outlet side of its upper pass and then extends downwardly into a sheet discharge gate through which defective sheets are effected.

Abstract: An apparatus for stacking sheets has a conveyor for delivering a succession of the sheets in a longitudinal transport direction on a conveyor plane to an upstream side of a stacking station with longitudinal edges of the sheets extending parallel to the direction. A vertically displaceable platform in the station below the plane receives the sheets in a stack. A row of upper feed belts extending in the direction immediately above the conveyor and the stacking station has lower reaches engageable down against the sheets on the conveyor at the upstream side of the station. A feed-belt adjuster moves the upper feed belts transversely of the direction and sets the upper feed belts in any of a plurality of different transversely offset positions.
