The invention relates to a method for regulating an extrusion device designed to manufacture a continuous strip of profiled product (P) in an elastomer mixture, comprising a screw (2) rotated in a stationary body (1), the output of which includes an extrusion die (5) and at least one cylindrical roller (3) that is rotated, the rotational velocity of the screw (&OHgr; screw) being directly related to the rotational velocity of the roller (&OHgr; roller) by a proportionality coefficient, said regulating method including the following steps: - for a given elastomer mixture and a given profiled product (P), a reference value Ks of the proportionality coefficient is determined - the thickness (e) of the profiled product (P) leaving the extrusion die (5) is measured at each moment and the value of the proportionality coefficient in Ks' is corrected, - the rotational velocity of the screw is corrected, taking into account the corrected value Ks' of the proportionality coefficient, such that &OHgr;' screw = Ks'* &OHgr; roller. According to the invention, the speed of the roller is adjusted on the basis of the corrected value Ks' of the proportionality coefficient. |
