Claim 33:
34. Method according to claim 33, comprising storing, on a storage support, values detected and digitalized of the electric signal associated both to a step of controlling a closure-start wherein a movement of ejection of a polymeric mixture by the cleaning member is provided, both to a step of controlling an opening-start of a delivery duct wherein the movement of returning of said cleaning member up towards the upper part of the outlet of a mixing chamber is provided until an end-of-stroke signal of a control piston enabling the opening of a valve member, slidingly movable in said mixing chamber, and the delivery of the mixture, obtaining from said stored values and a performance thereof information on process parameters representing operating conditions wherein the friction, scraping and bonding forces exchanged between the cleaning member and tubular element are indicative of possible degradation phenomena of the operating performances of such components.
