Abstract

A method cuts an extruded pipe to length using a separating device. The separating device includes 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 are configured to carry out the separation. The method includes transferring energy to move the cutting tools. 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 storage device. The energy is transferred inductively or capacitively. A discharge time of the energy storage device is between 2% and 25% of a total separation cycle.
