Abstract

A cutting unit for thermoplastic pipes includes a ring rotating about an axis and in which a pipe is progressively moved in a sliding fashion such that a longitudinal axis of the pipe coincides with said axis of rotation and a cutting arm mounted on the ring. A distance measurement sensor located on the ring is configured for acquiring, during rotation of the ring, values representing a radial distance between the measurement sensor and an outer surface of the pipe. The distance is measured on a measurement plane transversal to the axis of rotation. The cutting unit also includes a processing and control unit operatively connected to the measurement sensor and configured for receiving the values measured and for calculating, on the basis of the values, at least one parameter representing a peripheral profile of the pipe on the measurement plane.
