Abstract
The invention proposes a method for positioning protective screening ramps of a station for heating preforms, on the occasion of a change of format, the heating station comprising: —members for transporting preforms; —at least one pair of parallel longitudinal screening ramps for protecting necks against heat, which ramps are parted in order to leave a slot through which the preforms progress; —a motorized device for moving the ramps transversely. The method includes a preliminary calibration step which consists in arranging at least two calibration elements between the two protective screening ramps occupying an initial position, and manually causing the protective screening ramps to move into a calibrated position in which they are each in simultaneous contact with the two calibration elements.
