The invention relates to a method for winding a metal strip () into a reel with a winding mandrel (), to which the metal strip () is routed through a pair consisting of a first and a second driver roller (), at least one of which is driven. The method is characterized in that a difference between the strip speed (V) of the metal strip () and the speed) (v, v) of the driver rollers is adjusted on the basis of measuring, from measurable process variables, the strip speed and the speed (v, v) of at least one of the driver rollers ().

The invention relates to a method for controlling a lateral guiding device for a metal strip (), the lateral guiding device comprising a guide () disposed laterally to the metal band () on both sides thereof, it being possible for the two guides () to be displaced independently of each other, and both guides () being operated in a position-controlled manner, forces of the metal strip that act on a first guide () of the two guides () and on a second guide () of the two guides () being measured, and the target position for the first and/or the second guide () being controlled as a function of the forces measured at the first and at the second guide (), such that the lesser value of the forces measured at the first guide () and at the second guide () is above a selectable lower limit force and below a selectable upper limit force.

Method for controlling lateral guiding devices for a metal strip

The invention relates to a method for controlling a side guide of a metal strip (), in particular in the inlet or outlet of roll stands or driving apparatuses, wherein the side guide comprises a guide () disposed laterally to the metal strip () on both sides of the metal strip (), and the guides () can be displaced independently of each other. One of the guides () is thereby driven by means of position control, and a second of the guides () is driven by means of force control, wherein forces of the metal strip () acting on the first guide () and the second guide () are measured. The target force for the second, force-controlled guide () is thereby prescribed as a function of the measured force on the first, position-controlled guide (), wherein as the force on the first, position-controlled guide () increases, the target force for the second, force-controlled guide () is reduced. In particular, damage to the guides () and to the metal strip () can be prevented or at least reduced by means of said type of controlling.

The invention concerns a device () for measuring the strip tension in a metal strip, especially a steel strip, which device has a flat, level table (), over which the metal strip can run and at one end () of which a plurality of measuring elements () is mounted, which are suitable for measuring the strip tension, where cooling elements () are provided, which are installed under the table () and with which cooling liquid, especially water, can be carried into the area of the measuring element (). In order to secure the table against sagging in a simple way, the invention provides that the cooling elements () have a box-like cooling liquid tank (), which is arranged on both sides of the metal strip on at least one support member, such that the underside of the table () rests directly or indirectly on the box-like cooling liquid tank ().

A method for coiling thin metal strip, especially hot-rolled or cold-rolled thin steel strip, on a coiler mandrel which is adjusted in diameter. At the beginning, the inner windings of the coil are coiled on the adjusted coiler mandrel diameter and, after the final winding of the coil, the coiler mandrel is pulled out or the coil is taken off. At least the first inner winding is joined over a large area with the second inner winding by introducing adhesives, fillers, pieces of metal, bonding agents, or the like into an angular space between the inner windings.

A looper for measuring a wedge proportion of a longitudinal pull present within a strip in a longitudinal direction of the strip, wherein the wedge proportion is present across a width of the strip, has a looper shaft and pivot arms each having a first end and a second end, wherein the first ends are connected to the looper shaft. A continuous looper roll extends across the width of the strip and is supported on the second ends of the pivot arms, wherein the looper roll is adjusted relative to the strip by rotation of the looper shaft. Each pivot arm has a looper shaft arm, a looper roll arm, and a joint connecting the looper shaft arm and the looper roll arm to one another. A dynamometer is connected to each pivot arm, wherein the joints of the pivot arms deflect a return force, exerted by the strip onto the looper roll and corresponding to the longitudinal pull, onto the dynamometers, respectively.

A planarity measuring roller is constructed as a loop lifter which is adjustable relative to a rolled strip. The loop lifter includes a plurality of measuring zones located next to one another over the width of the rolled strip. Each measuring zone includes a rotatably mounted individual measuring roller which is pivotable in a clockwise direction and interacts with a force measuring device. Each measuring roller is mounted in a pivotable housing-like lever frame. The pivot point of each lever frame, the point of rotation of the corresponding measuring roller and a force introduction point of the force measuring device arranged underneath of the pivot point of the lever frame form an approximately isosceles triangle.

Planarity measuring roller

An arrangement for measuring the planarity of a rolled strip which is under tension in a hot strip rolling train with a roughing train and a finishing train including several roll stands and a reel. At least one measuring roller is arranged in rolling direction between the first roll stand of the finishing train and the reel, wherein the rolled strip is guided over each measuring roller, so that the measuring roller is bent as a result of the strip tension; in addition, pick-ups for measuring bending of the measuring roller are provided.

A sealed roll bearing of a roll which has neck sleeves of high strength, preferably shrunk onto the roll necks of the roll, wherein the flanges of a profiled sealing ring sealingly engage over the end portions of the neck sleeve facing the end faces of the roll bodies and at least over portions of the end phases of the roll bodies. The flanges of the profiled sealing rings engaging over the end faces of the roll bodies are connected to the end faces of the roll bodies and the flanges of the profiled sealing rings engaging over the end portions of the neck sleeves surround the flanges of the profiled sealing rings engaging over the end portions of the neck sleeves so as to form a narrow gap, wherein the narrow gap is sealed by means of at least one sealing device.
