  • Patent number: 11883867
    Abstract: 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.

  • Patent number: 5378082
    Abstract: A ship lifting installation (1) comprises a platform (3) for docking ships (2), which platform (3) can be lifted and lowered by means of lifting mechanisms (13). Mass-production lifting mechanisms (13) comprising a grooved cable drum (16) with a planetary gear unit located in the cable drum (16) are used in the ship lifting installation (1) and are provided with an electric motor (27) having an integrated brake, at least one upper cable pulley block (14) which is arranged separately from the cable drum (16) on a cable pulley support (20), and at least one lower cable pulley block (15) which is built into the platform (3).

  • Patent number: 5069427
    Abstract: A stand for exerting a forward or rearward drag upon metal strips or sheets, in particular for a plurality of narrow strips which are to be wound up together with separate braking drags being applied to each strip, between two oppositely disposed, endlessly circulating conveyor chain systems driven by chain wheels, wherein a belt arranged between at least one chain system and the metal strip prevents particles of dirt such as forging scale, zinc and tin fines, etc. from entering the chain case.

  • Patent number: 4792075
    Abstract: An apparatus for exerting a forward or rearward drag on a moving metal strip (9), for use in particular with narrow metal strips which are to be wound up together side by side and which are to have separate rearward braking drags applied to them, comprises two endless conveyor chain systems (3, 4) driven by chain wheels (23). Each of the chains of the systems is formed by a series of pivotally interconnected roller units (7) which are guided by guides (13) along a straight drag-applying zone (12) where the strip (9) is clamped between the units (7) of the systems (3, 4) and has a drag (8) applied to it. Further guide bars (17) are provided remote from the zone (12) and these bars (17) together with the chain wheels (14) and guide segments (15, 16) guide each conveyor chain (3, 4) along a path which is curved along its whole extent except where it passes through the straight drag-applying zone (12).

  • Patent number: 4638701
    Abstract: To enable band treatment installations to be continuously operated, the end of the band (1) passing through is welded with the start of a new band (2). In the joining of bands (1, 2) of different widths or when a band is offset, annoying corners or lateral projections frequently cannot be avoided. A shears for notching these regions or for cutting out segments (17) and strips (18) by means of a knife pair travelling into the band consists of an upper and a lower circular knife (3, 40) and possesses a pivoting drive (6) for moving the knife pair along a curve.

  • Patent number: 4527723
    Abstract: Strip processing lines require tension or back tension to be applied to the strip, as the case may be. These requirements are best met by the proposed chain bridle.The recoiling of adjacent slit strips on a tension reel will result in varying rewinding speeds and tensions due to the different thickness of the individual strands. Thick strands will be rewound too tight and thin strip too loose. Therefore, the chain bridle is installed before the tension reel to keep the tension of the various strands or a wide strip at a constant value. The strip (1) is clamped between two circulating chain systems (4a,4b), one arranged below and the other above the strip passline. One chain system (4b) is fixed, the other one (4a) is adjustable.
