A guiding roller for web material, in particular, for paper production and finishing machines, has a middle and two outer roller tubes. The adjacent ends of the middle and outer tubes are connected with each other by a bridging element in such a way that the middle and outer tubes are driven along with each other in a rotating and articulated manner. The middle and outer tubes have a common roller bearing which allows the roller tubes to be supported on a fixed roller axle with either a lesser number of roller bearings and/or by eliminating the use of spherical roller bearings. The common roller bearing of the adjacent ends has a thermal insulating material positioned between the roller bearing and the roller tube, thus eliminating an excessively high generation of heat from the roller bearings.
Rouleau de guidage pour matériau en bande, destiné en particulier à des machines de fabrication et de finissage du papier, comprenant un tube de rouleau médian et deux tubes de rouleau extérieurs. Les extrémités adjacentes des tubes médian et extérieurs sont reliées ensemble par un élément de raccordement, de façon que les tubes soient entraînés ensemble de façon rotative et articulée. Les tubes ont un roulement à rouleaux commun, qui leur permet d'être supportés sur un axe de rouleau fixe avec moins de roulements à rouleaux ou sans l'utilisation de roulements à rotule sur rouleaux. Le roulement à rouleaux commun des extrémités adjacentes possède un isolant thermique entre ce roulement et le tube de rouleau, éliminant ainsi une production excessive de chaleur par les roulements à rouleaux.
