The invention relates to a method for the automatic conducting of a straightening process for an object that is to be straightened, such as sheet metal, strips, sections, pipes, and in particular for wire-like or multiwire- like objects that are to be straightened, in a straightening device or a levelling machine with at least one mangle roll which can be adjusted by an actuator. In accordance with the invention, a process simulation model of a straightening process that is to be conducted, and a process simulation programme are set up, and the latter gives directly "online" the settings of the adjustable mangle roll(s). During the straightening process, changes in the product data, in particular the material characteristics and/or dimensions of the object to be straightened which influence the realization of the straightening process, are recorded, and from these, data for setting the adjustable mangle roll(s) are also calculated, and signals are emitted for the automatic setting of the adjustable mangle roll(s) by means of an actuator and/or actuators.

Procédé de déroulement automatique d'un processus de dressage pour un objet à dresser, tel que des tôles, des feuillards, des profilés et des tuyaux, et en particulier pour un objet de type fil ou de type à fils multiples, dans un appareil ou une machine à dresser doté d'au moins un rouleau à dresser réglable à l'aide d'un actionneur. Selon la présente invention, un modèle de simulation d'un processus de dressage à effectuer et un programme de simulation de processus sont élaborés, ce programme donnant en direct les paramètres de réglage du (des) rouleau(x) de dressage réglable(s). Lors du processus de dressage, des modifications des données concernant le produit, en particulier les propriétés du matériau et/ou les dimensions de l'objet, qui influencent le déroulement du processus de dressage, sont enregistrées, et sur la base de ces modifications sont calculées des données permettant le réglage du (des) rouleau(x) réglable(s). Des signaux destinés au réglage automatique du (des) rouleau(x) de dressage réglable(s) à l'aide d'un ou de plusieurs actionneurs sont alors émis.
