ABSTRACT:
A cross cutter for web stock, in particular for a corrugated cardboard web, has tube-shaped cutter cylinders (4, 5) formed of a composite fiber material which are rotatably mounted in pairs above each other in a machine frame (2, 3). Cutter holders (15) for cutters (16) are fastened on the cutter cylinders, which are disposed along the circumference of each cutter cylinder extending diagonally. Counterweights (17) are located on the cutter cylinders opposite the cutter holders. The cutter cylinders mesh with each other via gear wheels (10), by which the cutter cylinders can be driven. The cutter cylinders (4, 5), the cutter holders (15) and the counterweights (17) are made of a composite fiber material with a heat expansion coefficient near or equal to 0 mm/K. The bearings (7) at both ends of the cutter cylinders are fixed bearings. Because of the reduced flexing of the cutter cylinders, the optimum quality of the cut and, because of the reduced mass inertia moment, a reduced energy absorption can be attained by this.
