Device () and method for winding/unwinding rolled products (). The device () is interposed between a rolling unit located upstream () and a rolling unit located downstream (). The device () comprises a heating furnace () and a support structure () disposed outside the heating furnace (). On the support structure (), substantially in a diametrically opposite position, two winding/unwinding drums () are assembled, positioned inside the furnace (). The support structure () is selectively rotating to alternatively dispose a first of the two drums (or) in its winding position or in its unwinding position of a reel (). A second of the two drums (or) consequently assuming the opposite unwinding or winding position.

Winding/unwinding device and method for winding/ unwinding a metal product in a rolling line

An apparatus for the winding of striplike material, in particular steel strip, in each case on one of two spreadable winding mandrels which are arranged, overhung, horizontally and parallel to one another and which, driven in rotation independently of one another, are mounted, in a carrying structure rotatable about a common horizontal central axis, on a vertical carrying wall in the form of a circular disk. The carrying wall in the form of a circular disk is arranged coaxially at the end of a central carrying shaft mounted, at its end opposite the carrying wall, in a rotary bearing. The gears for the winding mandrels are arranged, on the side of the carrying wall which faces away from the winding mandrels, in selfsupporting cases with cover division, which are connected to the carrying wall and with the latter form the carrying structure and which are themselves connected supportingly to at least one carrier which is fastened, overhung, to the carrying wall, so as to be parallel to the carrying shaft, and which, between the gear case and the rotary bearing, carries the drive motors for the winding mandrels, said drive motors being arranged on brackets.

Carousel coiler with two coiler arbors

A device for winding strip-type material, especially steel strip, alternately on each of two expandable coiler drums arranged horizontally and parallel to one another, which are mounted in free-floating fashion in a carrying frame arranged in rotary-drivable fashion around a shared horizontal central axis and are themselves rotary-drivable independently of one another. The rotary drives for the coiler drums together with the carrying frame are attached to the frame in rotatable fashion. The drum-type carrying frame consists of two vertical circular-disk-type carrying walls which are separated from and parallel to one another. Longitudinal traverses connect the carrying walls together. On the longitudinal traverses are mounted the coiler drums, which penetrate one carrying wall, and their expanding drives. Flanged onto the outside of the other carrying wall are the simultaneously drivable rotary drives, which are connected to the coiler drums through universal joint shafts in geared fashion.

Carrousel-type coiler with two coiler drums

A drum-type shear for cutting high-speed strip, especially hot strip, includes a blade that is movable radially into and out of a rotating blade drum from which it is extendable into a strip-cutting position at a desired cutting time. In order to provide reliable and accurate cross-cutting of even broad and thick strips using nevertheless simple structural means, a linearly translatable push-pull rod that extends axially in the blade drum has wedge surfaces that abut with corresponding wedge surfaces of the blade or blade holder for extending and retracting the cutting blade. The push-pull rod rotates with the blade drum and is connected to a stationary linear drive via a thrust bearing for transmitting axial rod-translating forces to the push-pull rod as the rod rotates with the drum.

Apparatus for cutting a high-speed strip

The invention refers to an expandable mandrel reel to coil strip-like rolling material, particularly hot strip, with an inner mandrel shaft, as well as several expanding segments affixed to the latter. The segments are spread by activating a tie rod, and are supported on several wedge faces on the mandrel shaft and rising in the longitudinal direction of the shaft. Means are provided for keeping the expanding segments in place against centrifugal force.
