  • Patent number: 6349585
    Abstract: 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 machine is arranged between the gear unit of the shear and the drive motor, wherein torsion-proof couplings are arranged between the gear unit or the shear and the gear mechanism and between the gear mechanism and the drive motor.

  • Patent number: 4869437
    Abstract: A wire coiling apparatus with extraction device for a coiled wire reel (B) with a coiler basket, comprises two concentrical circular rows of basket rods (1, 4) which stand vertically upon a base plate (3). The base plate (3) can be rotatably driven around a stationary vertical bearing. A reel lifting plate (8) is arranged above the base plate (3) between the circular rows of the basket rods (1, 4) which plate can be moved up and down by means of a central lifting rod (7) in the direction of the central axis of the coiler basket. The basket rods of the outer and/or inner circular row are supported in the base plate so as to be rotatable around their longitudinal axis and they can be arrested in at least two rotational positions. The profile of the basket rods is herein designed in such a manner, that the wire contact faces (AF.sub.1, AF.sub.2) of the basket rods facing the central axis of the coiler basket in these different rotational positions, have different spacings (d.sub.1, d.sub.
