MACHINE FOR CROSSCUTTING WEBS OF MATERIAL

摘要

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.
