<p>A method and an apparatus by means of which a capsule (11) fitted onto a bottle (12-120) is rendered coaxial to the bottle (12-120) by means of a drop-down head (20-220) provided with a rigid centering sleeve (21-210) and with a pneumatic tightening sleeve (23-230), which is suitable to produce a preliminary partial coupling of the capsule (11) to the cork (T) of the bottle, after the capsule has been centered with respect to the bottle by the first sleeve. The partial and preliminary coupling of the capsule is achieved by compressing the end of the capsule onto the cork (T) of the bottle by means of the pneumatic tightening sleeve (23-230), into which compressed air is fed temporarily. <IMAGE></p> |
