Abstract
L'invention concerne un mécanisme à fermer un sac rempli. Le mécanisme comprend une barre plieuse chauffée (20) qui plie la partie supérieure d'un sac en position fermée et applique simultanément de la chaleur sur cette partie supérieure repliée de façon à activer un adhésif thermosensible (A) disposé entre le segment replié de la partie supérieure du sac. Une barre directrice (30) est conçue et disposée de manière à comprimer la partie supérieure repliée du sac pour refroidir l'adhésif thermosensible.
