Abstract

La présente invention concerne une machine de conditionnement de type VFFS (formeuse-ensacheuse-scelleuse verticale), dans laquelle une bande de matière (23) de formage de sachets est entraînée vers le bas à une vitesse à cycle variable, de manière à ce qu'elle entoure un dispositif de formage (24) et que les bords de la bande se chevauchent. Cette machine comprend un dispositif (10) à air chaud permettant de diriger l'air chaud sur les bords en chevauchement afin de les sceller. Cette invention est caractérisée en ce que ledit dispositif (10) est alimenté en air au moyen d'une soufflante à vitesse variable (13) qui fait varier automatiquement la vitesse de l'air chaud dirigé vers les bords de la bande, en fonction de la vitesse de celle-ci.
