The invention relates to a segmented roll comprised of a plurality of end-to- end mounted roll segments (10, 10'), each adapted to rotate on bearings supported on a separate support shaft (11). In both axial end surfaces of the support shafts (11) of the roll segments (10) there are coupling means such as an annular projection and an annular recess serving to disengageably connect two adjactent roll segments (10) to each other. The support shaft (11) contains of at least two parts (16, 18) whose mutual disposition is made alterable for the purpose of altering the axial length of the support shaft (11) so much that the coupling means (29, 41) of the facing axial ends of two adjacent roll segments (10) can be engaged and disengaged with each other. This arrangement makes it possible to change a single roll segment from the central area of the segmented roll without the need for disassembling the entire row of roll segments.
L'invention porte sur un rouleau segmenté en plusieurs segments (10, 10') montés bout-à-bout et conçus pour tourner autour de paliers montés sur un arbre support (11) séparé. Les deux surfaces des extrémités de l'arbre support des segments (10) comportent des moyens de couplage, par exemple une projection annulaire et un évidement annulaire, permettant de relier réversiblement entre eux deux segments (10) de rouleau voisins. L'arbre support (11) se compose d'au moins deux parties (16, 18) dont la position relative peut être modifiée pour en (11) faire varier la longueur axiale, et par là, engager ou désengager les moyens de couplage (29, 41) des faces des extrémités de deux segments (10) de rouleau voisins. Cette disposition permet de changer un seul segment de rouleau de la zone centrale du rouleau segmenté sans devoir démonter la rangée entière de segments.
