Abstract

La présente invention concerne une machine à fabriquer des tubes de papier présentant une trajectoire de déplacement guidant le déplacement d'une nappe de papier possédant une pluralité de rainures découpées et comportant un dispositif de cintrage de nappe qui forme un tube de papier par un processus de cintrage de la nappe de papier. Ledit dispositif de cintrage de nappe comprend une courroie à garniture, une partie de façonnage des tubes et un applicateur. Lors du processus de déplacement de la nappe de papier, la partie de façonnage des tubes maintient la surface intérieure de la nappe de papier à l'état libre tout en donnant en continu à la nappe de papier la forme de tubes de papier au moyen de la courroie à garniture, si bien que le tube de papier comporte une partie enroulée au niveau de laquelle les deux bords de la nappe de papier se chevauchent. Dans le même temps, l'applicateur applique un adhésif sur l'un des deux bords latéraux de la nappe de papier avant la formation de la partie enroulée de façon à ce que les deux bords latéraux adhèrent l'un à l'autre.
