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.

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 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.

A device for applying coiling-tension to a slit band sheet (1) includes: an upper structure (3) that is disposed on the upper side of a band sheet (2) which has been passed through a slitter line and slitted; and a lower structure (4) that is disposed on the lower side of the band sheet (2). The upper structure (3) includes two cooling rolls (6) over which an upper belt (5) is stretched, and an upper pressing part (7) that is disposed between the cooling rolls (6). Further, the lower structure (4) includes two cooling roller (9) over which a lower belt (8) is stretched, and a lower pressing part (10) that is disposed between the cooling rolls (9).

The invention may relate, among other things, to a device for straightening a metal strip having two strip drives which are suitable together to apply tension on the metal strip to straighten the metal strip, wherein at least one of the strip drives is a linear drive, characterized in that the at least one linear drive has a positioning device such that the linear drive can be moved relative to the longitudinal axis of the device.
