The invention relates to a device (1) for measuring the width (B) and/or the position of a metal strip (2) or a slab, which has at least two measuring systems (3, 4), with each located on a side (5, 6) of the metal strip (2) or the slab, wherein each measuring system (3, 4) has a sensor (7) designed to detect the lateral end (8, 9) of the metal strip (2). To make the measuring device robust and to enable dynamic measurement, according to the invention the sensor (7) is located on a moving element (10) with which it can be moved in a straight line in a direction (Q) at right angles to the longitudinal direction (L) of the metal strip (2).

The invention relates to a method and an apparatus for winding up metal strips (2) onto a winding mandrel (3), which is arranged in a reeling shaft (1) and to which the metal strip is passed by a driver having a lower and an upper driver roller (5, 6), wherein a table (7) is provided underneath the metal strip (2) for guidance and a pivotable strip diverter and, adjoining the latter almost up to the winding mandrel (3), a pivotable shaft flap (11) are arranged above the metal strip. By measuring the strip tension in the reeling shaft, it is intended to regulate the driver in such a way that the running of the strip makes it possible for the metal strip to be wound up to form a coil with straight edges. To achieve this, the longitudinal tensile force exerted on the metal strip (2) by the driver is determined by means of a strip tension measuring device (13), which dips into the metal strip from above in the reeling shaft (1), and the measuring signal is passed to a driver regulating device (22) to control the running of the strip by the driver. In the case of an apparatus suitable for this purpose, the strip diverter is formed as a strip tension measuring device (13) which dips into the metal strip (2) from above and is provided with a diverter body, which has a rotatably mounted roller arm (16), carrying a roller (17) at its front end, wherein a force measuring means (20) that is connected in signalling terms to the regulating device (22) is arranged between the diverter body and the roller arm (16).

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.

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 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.

The invention relates to a reel mandrel (1) for winding sheet metal, in particular rolled hot strip, comprising a mandrel body (2) preferably configured as hollow-cylindrical, a spreading bar (3) which can be adjusted relative to the mandrel body (2) in the axial direction (A) and a number of segments (4) which are radially adjustable by axial movement of the spreading bar (3) relative to the mandrel body (2), wherein a number of links (5) pivoted on the spreading bar (3) and the segments (4) are arranged between the spreading bar (3) and the segments (4). In order to make such a reel mandrel suitable for winding high-strength and super high-strength materials, the invention provides that in the mounted state of the reel mandrel (1), at least a number of links (5) pass through recesses (6) in the mandrel body (2) which are inserted in the mandrel body (2) such that this is at least free from recesses (6) at its axial ends (7).
