Method for the axle correction of a processing machine, and a processing machine

Abstract

In a method for the axle correction of a processing machine which includes—in order to convey and process a continuous material—at least two driven conveyance axles, at least one non-driven or driven processing axle, and at least one further non-driven axle, while the rotational speed of a driven axle is being changed, a precontrol of this axle and/or a processing axle is carried out with consideration for the elasticity module of the web material, and with consideration for a rotational inertia of at least one non-driven axle, the elasticity module of the material which comprises the continuous material being determined automatically; and a related processing machine is provided.
