A device for transmitting a torque from a drive device () onto a roller in a roll stand. In order to make the device independent from the continuous external supply of lubricant, the lubricant spaces in the two pivot bearings are connected to one another in a fluidically conductive manner by way of a feed channel and a return channel for the lubricant in the region of the spindle such that a closed circuit for the lubricant is formed, and that the least one pump device is integrated in the circuit in order to maintain the circulation of the lubricant in the circuit.

Device for transmitting a torque from a drive device onto a roller in a roll stand

A high-speed shear for transversely cutting rolled strip with knife carriers which can be driven for rotation and are arranged in pairs opposite each other. The knife carriers are supported on shafts of gear wheels arranged at a fixed axial spacing in pairs opposite each other in a shear cassette. The shear cassette is mounted within an outer frame and the shear cassette is provided with a lifting device for raising or lowering the shear cassette within the outer frame. In a method for operating the shear, the two knife carriers are moved into a horizontal position for allowing the strip end to enter or travel through, and the shear cassette is moved within the outer frame into a raised transfer position.

The invention relates to a device for transversally cutting a rolled strip using shears, especially drum shears. According to the invention, a gap between the end of the roller table upstream of the shears and the beginning of the roller table downstream of the shears, where there is no support for the rolled strip, is reduced by a pivotable roller table part supporting the rolled strip as it passes through, and a mobile guiding table is arranged between said pivotable roller table part and the beginning of the rear roller table.

Device for transversally cutting a rolled strip

A method of operating a flying shear for cutting a rolled strip, which includes at least one drum provided with a blade, includes synchronizing a peripheral speed of the blade with a feed rate of the rolled strip, and cutting the rolled strip by effecting a partial penetration of the blade in the rolled strip to produce a weakened location of the rolled strip, and by tearing the rolled strip at the weakened location by a tensile force.

The aim of the invention is to configure a device for winding and unwinding partly rolled products, in a way that ensures the smallest possible accumulation of scrap. To achieve this, a roller (&#x2033;) whose position is controlled and which runs on the periphery of the coil is used during the transfer of the coils from the winding station to the unwinding station. The vertical adjustment of said roller ensures that the coil is completely unwound, even with a diminishing coil diameter.

A high-speed shear for cutting a rolled strip to a length and including first upper and second lower blade drums carrying, respectively first and second blades and rotationally connected with each other, drive elements located in front of and behind the first and second drums for advancing the rolled strip, under longitudinal tensioning, through a blade gap between the first and second drums, and support rollers supporting the tensioned strip and providing for lifting of the strip before passing of the second blade and for lowering the strip before passing of the first blade through the blade gap.

High-speed shear for transverse cutting of a rolled strip

A high-speed shear with a knife, particularly a chisel-type knife with a knife edge, arranged on at least one of two oppositely arranged drums, wherein the knife can be accelerated to the feeding speed of the rolled strip and the drums can be adjusted relative to each other for carrying out a cut. At least one drive unit provided for the drums serves to accelerate the drums to the speed of the rolled strip to be cut and at least one of the drums may be provided with a separately controllable adjusting device. The chisel-type knife of the knife drum is mounted so as to protrude from the cutting circle towards the anvil or the surface portion of the second drum acting as an anvil and to mount the chisel-type knife of the knife drum so as to be resiliently supported against a predetermined restoring force.
