Abstract: A loop lifter for continuous strip rolling mills has an arm which is journalled in a support for pivotal movement about a horizontal axis. An end portion of the arm carries a freely turnable roll which can engage a loop from below and lift it upwardly. A counter balancing spring reacts between a fixed pivot and the arm and assures that the pivot shaft for the arm is not subject to any free torque during pivoting movement of the arm between 0.degree. and 90.degree. of arc.

Abstract: A hot rolling mill and a method of operation to reduce scrap upon failure of a portion of the mill in which a first furnace device is provided adapted to receive and reel up a strip which is ready to go to the finishing section of the mill and a second furnace device is provided to receive a strip of material being rolled in the roughing section of the mill without reeling up, while both furnace devices maintain the material therein at working temperature and in continuous motion.

Abstract: A hot rolling mill and a method of operation to reduce scrap upon failure of a portion of the mill. A first furnace device is provided in the mill adapted to receive and reel up a strip which is ready to go to the finishing section of the mill.

Both furnace devices maintain the material therein at working temperature and in continuous motion.

Abstract: An arrangement for marking articles or workpieces, particularly hot workpieces, such as coils of sheet metal with series of symbols which are individually applied in templates. The latter are in the form of symbols applied in a cylindrical portion and in a flange-like portion of a movable angle ring which is adjustable vertically and sideways. A spray nozzle is associated with each of the portions. The angle ring is connected to a trunnion fixed in an arm which is adjustable vertically and sideways by piston-cylinder units. One piston-cylinder unit is centered in a frame which is movable on a track by driven wheels, and the piston of this unit mounts a lifting table. Another piston-cylinder unit is connected to the aforementioned arm. One vertical spray nozzle is located above the flange-like portion of the angle ring on the outer end of the arm.

Abstract: A device for preparing metal sheets for transport wherein the sheets are delivered on a conveyor belt from a shearing region to a stacking region in which the sheets are engaged from above at the discharge end of the conveyor belt and transported longitudinally and deposited on selected ones of tables to build up stacks of sheets. The stacks of sheets are moved laterally by lateral movement of the tables or by laterally extending chains to a lifting station wherein the stacks of sheets are engaged from above by cranes and conveyed thereby to a binding station for binding of the stacks of sheets.

Abstract: A shearing arrangement for cutting moving bars in which two counter-rotating knife drums are rotatable in shear stands. These stands are spaced from each other and are located on a base plate. They are connected to each other above the knife drums by a disconnectable yoke. Both knife drums are mounted directly in the shear stands which are each of single-piece construction. The shear stands are inserted into the base plate and are connected to the base plate by quick-disconnect couplings. The quick-disconnect couplings between the shear stands and the base plate may be in the form of press rods, and the base plate may have lateral inclined guide surfaces or prisms for the shear stands. The knife drum is connected to its drive by an easily disengageable coupling which has a hydraulically shifted clutch sleeve.

Abstract: For use in connection with an underground reel in a rolling mill for band-shaped rolling stock, a two-roll driving device, with an upper driving roll and a lower driving roll which are arranged one above the other. When looking in the direction in which the rolling stock enters the reel, the axle of the upper driving roll is during the entry of the start of the rolling stock into the reel located behind the axle of the lower driving roll and after the start of the band-shaped rolling stock has been grasped by the winding mandrel of the reel the upper driving roll is pivotable into a position vertically above the axle of the lower driving roll, while behind the lower driving roll there is provided a deviating device for the band-shaped rolling stock. The upper driving roll is journalled in a stand which is pivotable about the axis of the lower driving roll and adjustable relative to the latter.

Abstract: An arrangement for cooling hot rolled steel bands reeled into coils, according to which the rolling hot steel band after having been rolled into coils are cooled in a liquid bath.

Abstract: An intake device for a band rolling mill, which includes an upper driving roller and a lower driving roller adjustable relative to each other and forming with each other a bite into which the band to be rolled is fed by the driven rollers of a lower roller bed and the driven rollers of an upper roller bed while both roller beds form with each other a wedge-shaped feeding funnel pointing toward the bite formed by the upper and lower driving rollers. The angle which the upper and lower roller beds form with each other is variable at will.

Abstract: A reel system, especially for rolling up strip steel, in which a rotatable housing is provided which has two circumferentially spaced spindles extending therefrom parallel to the axis of the housing, a gear in the housing is provided for each spindle and each spindle can be clutched to the housing or to the respective gear. A motor on the outside of the housing drives a gear meshing with the first mentioned gears while a ring gear on the housing meshes with a motor driven pinion for rotation of the housing. The housing carries clamp arms actuatable for clamping a wound up reel on each spindle. The arrangement permits each spindle to be positioned selectively in reeling up position for winding up a reel while the other spindle is positioned for discharging a reel previously wound up thereon.
