Abstract
Inventia se refera la un procedeu, conform caruia, pe baza unei tendinte cunoscute a cariatiei erorii determinate de un compartiment diferit al benzii de laminare, se introduc elemente de corelatie corespunzatoare în valoarea erorii determinate si sealimenteaza într-un sistem de comanda cu polaritate opusa. dispozitivul pentru realizarea procedeului format dintr-un convertizor de actionare, cu o directie predeterminata a erorii, este interpus între un mijloc de masura a vitezei de tragere si si stemul de comanda. Un al doilea convertizor de actionare cu o directie predeterminata a erorii determinate de variatia laminarii, este interpus între instrumentul de masura a gradului de laminare si sistemul de comanda. este destinata industriei textile.The invention relates to a process according to which, on the basis of a known crash of error caused by a different compartment of the strip, corresponding correlation elements are introduced into the determined error value and seals in an opposite polarity control system. the device for carrying out the process consisting of a drive inverter with a predetermined error direction is interposed between a means of measuring the firing speed and the control stem. A second actuator with a predetermined error direction determined by the variation of the lamination is interposed between the roll-measuring instrument and the control system. is intended for the textile industry.
