Title:
METHOD AND DEVICE FOR STRAIGHTENING WIRE OR STRIP MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/172694
Kind Code:
A3
Abstract:
The invention relates to a method for straightening wire or strip material by means of a straightening device comprising straightening rollers (3, 4, 6, 10) engaging on opposite sides of the passing-through material (1) in an offset manner, some of which are automatically adjusted according to a model which has been stochastically determined on the basis of input data of the material and data relating to the wire and the straightening device that is determined during the passing of the material through the straightening device, such that requirements of straightness are met, wherein the position of at least one straightening roller is continuously adapted on the basis of said data detected during the passage through the straightening device, which data is representative of the target straightness, wherein (i), the size and direction of the forces acting on the straightening rollers and/or (ii) the temperature of the material before and after passing through the assembly of straightening rollers and/or (iii) the position of the material are measured after each of the straightening rollers and the obtained measurement values are input into the model controlling the adjustment of the adjustable straightening rollers. The invention also relates to a device for carrying out said method.
