An apparatus for processing metallic strip material comprises a feeder for feeding strip material; a strip drive with at least one controllable traction drive with a carrier and a motor, a drivable traction loop and a press assembly, wherein the power of the motor and the pressing force of the press assembly are variably controllable; a roller assembly for flexible rolling; a measuring device for measuring a physical parameter of a component acting on the strip material; wherein the driving power of the motor is controllable on the basis of the physical parameter measured by the measuring device.

A device for applying coiling-tension to a slit band sheet includes an upper structure that is disposed on the upper side of a band sheet which has been passed through a slitter line and slitted; and a lower structure that is disposed on the lower side of the band sheet and faces the upper structure vertically. In addition, an upper belt is stretched on an outer peripheral surface of the upper structure. A lower belt is stretched on an outer peripheral surface of the lower structure. The upper structure has a first reversing portion, an upper pressing portion, and a second reversing portion. The first reversing portion and the upper pressing portion are integrated with each other. A tension adjusting mechanism is installed on side surfaces of the first reversing portion and the upper pressing portion and a side surface of the second reversing portion.

The invention relates to a device for rolling, in particular for stepped rolling, of rolling stock with at least one pair of rolls and at least one linear drive arranged downstream of the pair of rolls in the rolling direction, which together with the pair of rolls can apply tensile stress to the rolling stock, and with means for detecting the tensile stress. In order to enable an improved method of flexibly rolling stock, the rolling device is characterized by means for detecting the tensile stress and by a control device for controlling the drive power of the linear drive as a function of the tensile stress detected, in order optionally to vary the tensile stress applied to the stock or to keep the tensile stress constant as the drive speeds behind the roll gap change. The invention also relates to a method of rolling the rolling stock using such a device.

A bridle device and a method for producing a steel strip in which snaking of a steel strip that occurs during production of a high-silicon steel strip is suppressed. The bridle device includes a pair of upper and lower rotatable endless belts or a pair of upper and lower rotatable caterpillars configured to pinch a steel strip. The bridle device is movable or swingable in a steel strip width direction by using a steering mechanism. The bridle device further includes a rolling reduction mechanism configured to perform rolling reduction on a pinched portion of the steel strip by using the pair of upper and lower endless belts or the pair of upper and lower caterpillars. The steering mechanism moves or swings the bridle device in the steel strip width direction, and the rolling reduction mechanism performs rolling reduction on one of end portions in the steel strip width direction.

A device for transporting elongated metal material comprises two chain drive units with a continuous chain, which are arranged such that the elongated material is passed through between the chains with frictional contact so that the elongated material is moved; two controllable pressure units configured to apply pressure forces to the chains towards each other; at least one controllable adjusting unit which is mechanically connected to at least one of the chain drive units and which is configured to move same in a longitudinal direction of the elongated material during operation. A plant can have such a device, and a process is used for controlling such a device.
