Definitions

  • the present invention relates to a winding station and a method for winding a plurality of metal strips into a plurality of rolls of tape and the use of special electric motors for winding stations.
  • Such winding stations are used in particular in combination with cutting machines, for example of the type of strip cutting machines or foil cutting machines, by means of which a metal strip or a metal foil can be cut primarily in a longitudinal direction of the metal strip or metal foil, so that a plurality of metal strips or metal foils can be made formed by metal strips.
  • Corresponding winding stations are, for example, from EP 2 752 381 A1 known and regularly have a winding shaft which is rotatably attached to a frame.
