  • the invention relates to a method and a device for deflecting a roller core that moves at high speed.
  • the z. B. can also be designed as a deflector flap, it can lead to a breakout of the roller core and thus to an accident at high roller core speeds.
  • the technical effort for generating the magnetic field can be assessed as considerable.
  • the magnetic field in the magnetic coil is not very strong due to the large dimensions of the same and the relatively large distance from the magnetic field of the rolling core and is therefore only suitable for limited applications.
  • the power supply via sliding contacts hardly seems practical since the wear strips would be used up very quickly at high rolling speeds. It is also not clear how the vein should be held on the strips.

  • the electrical current is transmitted to the rolling wire without contact by means of an arc. Precisely because of the small effective distance of the magnetic fields acting on one another as a result of these measures, the prerequisite for the generation of correspondingly high magnetic forces is given. It has been shown to be particularly suitable if the electromagnetic force is defined in a predetermined core section of the roller core and is applied in an abrupt manner.

  • the electromagnetic effect is used to produce high-speed shears, it being particularly advantageous to dispense with large masses to be moved, cost-intensive drives and control technology.
  • the electromagnetic force acting is used as a deflecting force for guiding the rolling wire in a direction other than the rolling direction.
  • the electromagnetic effect becomes.

B. scissors and the switch according to the invention can be kept extremely low. Furthermore, the proportion of wearing parts is significantly reduced.
