  • the empty pipe is mostly unwound from a roll and fed to the corresponding device as a blank with a length that is, so to speak, "infinite". It depends on the accuracy of the cutting to length and, for economic reasons, also on the speed and throughput of the device.
  • the empty pipe is first positioned axially on a cutting device by means of a feed wheel and then cut through by this at a cutting position.
  • the generic DE 298 23 651 U1 relates to a device for positioning corrugated pipe hoses, with at least one feed wheel for the corrugated pipe hose, a positioning device for the corrugated pipe hose that interacts with a sensor, and a cutting device. It is proposed that at least one feed wheel has an external toothing which is adapted to the corrugation distance of the corrugated pipe hose and which engages in the corrugation troughs of the corrugations of the corrugated pipe hose. Together with one with the At least one indicator device coupled to the feed wheel is intended to provide a positioning device for the corrugated pipe hose.
  • JP 2004 314183 A which also relates to a device for positioning and cutting corrugated tubing.
  • the present invention is therefore based on the object of providing a device and a method for cutting an empty pipe, the disadvantages of the prior art being avoided and in particular a sufficiently precise axial positioning of the empty pipe on the cutting device being made possible.
  • the invention is based on the object of providing a computer program product with program code means in order to carry out a method for cutting an empty pipe which is improved with regard to the prior art.
