A method and an arrangement for operating a rotating starting shear operating in a start-stop operation on rolling stock travelling at different speeds in wire mills, light-section mills, medium plate mills and billet mills, wherein the shear, whose gear system is connected through a coupling to a drive motor, is accelerated from the position of rest to approximately rolling speed and, after the cut has been carried out, is stopped again. A gear mechanism is arranged between the gear unit of the shear and the drive motor, wherein torsion-proof couplings are arranged between the gear unit of the shear and the gear mechanism and between the gear mechanism and the drive motor.

Method and arrangement for operating rotating starting shears

A laying tube for producing wire windings from continuously introduced essentially straight wire material includes a first portion of an outer casing which is driven so as to rotate and receives a feeding tube for the wire material. Connected to the first portion is an outwardly expanding portion of the outer casing which includes a curved wire guide channel, wherein this guide channel is provided in the form of a groove in the outer surface of a hollow insert which is placed with fit in the expanding portion of the outer casing, and wherein the centrifugal forces of the wire are absorbed by the inner surface of the outer casing. The feeding tube and the insert form a structural unit which is releasably connected to the outer casing. This structural unit and, thus, the impact surfaces of the centrifugal forces of the wire can be moved in dependence on the localized wear of the inner surface of the outwardly expanding portion of the outer casing and relative thereto by a rotary movement about the longitudinal axis to an area which has not yet been worn out.
