The invention relates to a method for expanding the use of a coiling and uncoiling station (coilbox) located between the roughing train and the finishing train for rolled strip material in hot-rolling mills. The use of said coilbox is expanded by impinging the coil that is to be uncoiled with a pressing force (F) which acts in the direction of the roller table () and/or placing the coil in a depression of the roller table in order to process smaller coil weights in a spikeless coilbox, and/or by combining, in a chronological and weight-related manner, the active transfer and passive transfer of a coil from a first coiling station to a second coiling station in order to increase the throughput especially at average coil weights in a spikeless coilbox, and/or by supplying heat to the strip upstream or downstream of the spikeless coilbox and/or thermally insulating the strip or the coilbox in order to variably increase and homogenize the strip temperature. The invention further relates to a correspondingly equipped device for carrying out said method.

A method and device for measuring and adjusting the evenness and/or tension of a stainless steel strip () during cold rolling in a 4-roll stand () provided with at least one control loop () comprising several actuators (), resulting in more precise measurement and adjustment due to the fact that an evenness defect () is determined by comparing a tension vector () with a predefined reference curve (), whereupon the characteristic of the evenness defect () along the width of the strip is broken down into proportional tension vectors () in an analysis building block () in a mathematically approximated manner and the evenness defect proportions (C. . . Cx) determined by real numerical values are supplied to respectively associated control modules () for actuation of the respective actuator ().

The aim of the invention is to configure a device for winding and unwinding partly rolled products, in a way that ensures the smallest possible accumulation of scrap. To achieve this, a roller (&#x2033;) whose position is controlled and which runs on the periphery of the coil is used during the transfer of the coils from the winding station to the unwinding station. The vertical adjustment of said roller ensures that the coil is completely unwound, even with a diminishing coil diameter.
