In a method for axial correction in a processing machine (100), which has at least two driven transport axles (110, 115) for transporting and processing a product web (101), at least one non-driven or driven processing axle (111, 112, 113, 114), and at least one additional non-driven axle (102, 121, 122, 123, 124), wherein the product web (101) is divisible into at least one web-tensioning segment, a web-tensioning segment is delimited by two clamping points (110-115). The clamping points are embodied in the form of driven transport or processing axles. During a rotation speed change of a clamping point (110-115) a web-tensioning segment is delimited, a pilot control of this clamping point (110-115) delimiting the web-tensioning segment and/or of a processing axle (111-114) situated in this web-tensioning segment is carried out, taking into account a moment of inertia of a non-driven axle (102, 121-124) situated in this web-tensioning section, and a corresponding processing machine (100).
