  • the milled surface is smoothed by means of a scraper, whereby a chip separated from the coating material is formed. This chip is also referred to as Ziehspan.
  • the chip length usually corresponds to the length of the coating material. If, for example, a workpiece with a length of 2 meters, on whose narrow side a corresponding coating material has been applied, a 2 meter long chip is separated from the coating material. This can lead to a disturbance on the processing machine, in particular if the separated chip passes into specific units of the processing machine. To prevent this, a device is used with which the Ziehspan can be crushed.
  • the DE 10 2004 019 316 A1 relates to an apparatus and a method for edge processing.
  • the processing device comprises a processing device for separating an edge section in the case of plate-shaped or strip-shaped workpieces, whereby at least one chip is formed.
