Device and method for cutting an extruded pipe to length

A method for cutting an extruded pipe to length using a separating device comprising a separator rotating about an extrusion axis of the extruded pipe, the separator being rotatably mounted in the separating device, and cutting tools being arranged on the separator, the cutting tools configured to carry out separation, the method comprising:

• transferring energy to move the cutting tools, wherein:
• the energy is transferred from a stationary outer region of the separating device to a movable inner region of the separating device,
• the energy is transferred continuously or cyclically and the transferred energy is buffered in an energy store,
• the energy is transferred inductively or capacitively, and
• a discharge time of the energy store is between 2% and 25% of a total separation cycle wherein the energy is buffered in the energy store to move the cutting tools to carry out the separation.
