Cross cutter and method for material- and / or thickness-dependent adaptation of the relative cutting position of a rotating knife to the cutting position of a stationary knife in a cross cutter

摘要

The invention relates to a cross cutter (1) for cutting, perforating and / or severing a running material web of preferably paper, cardboard, plastic, composite material and / or metal, with a rotation axis (4) extending transversely to the material web and its conveying direction (3) ), wherein the blade shaft (2) has at least one circumferential knife (5) extending in the axial direction, and with a stationary knife carrier (8), the stationary knife carrier (8) extending substantially in the direction of the rotating knife (5) has transverse to the web extending and in a separation zone for cutting with the rotating blade (5) cooperating stationary knife (9). According to the invention, at least one setting means is provided for adjusting at least two different positions of the axis of rotation (4) of the knife shaft (2) in and / or against the conveying direction (3) of the material web and / or perpendicular to the conveying plane of the material web.
