Abstract

L'invention concerne un procédé et un appareil permettant d'emballer un article (30) avec un matériau d'emballage en bande. Cet article passe d'abord devant un dispositif d'emballage (3) doté d'un distributeur (1), qui tourne autour de l'article (30) sur un trajet circulaire, dans un premier plan de rotation. Un dispositif de retournement (15) amène ensuite l'article dans un deuxième plan de rotation qui est en pratique perpendiculaire au premier plan de rotation. Entre ces deux phases la surface de la bande de matériau d'emballage pivote de 90° environ de façon à rester en permanence perpendiculaire à ces plans de rotation.
