Abstract

L'invention concerne une barre de retournement pouvant être sollicitée par de l'air de soufflage, sur laquelle aucune opération de modification ou de suspension ne devrait intervenir lorsque la bande de papier change de direction. A cet effet, la barre de retournement comporte un tube de guidage muni d'orifices d'évacuation d'air d'un côté, c.-à-d. sur le côté faisant face à la bande de papier, ledit tube étant monté aux deux extrémités, de façon solidaire du bâti latéral, dans des éléments de fixation. Au moins un élément de fixation comporte une rainure de guidage prévue pour une bande d'entrée et pouvant être sollicitée par de l'air de soufflage. Le tube de guidage peut être monté de manière à pouvoir tourner à 180° autour de son axe de rotation pour passer de manière facultative d'une position finale dans une seconde position finale.
