CA 2248593

The invention relates to a take-out roll, spreader roll, or equivalent for a web-like material, which roll (10) comprises three parts linked with one another, i.e. two end parts (12) and a middle part (11), which parts are pivotal with respect to one another for the purpose of bending the roll (10) into a desired curved shape. In the invention, the middle part (11) of the roll (10) is constructed to also operate as a revolving axle of the roll (10), which is mounted revolvingly on its support members by means of end bearings (19). The end parts (12) of the roll are mounted, in the area of their axial inner ends, on the middle part (11) by means of articulation devices (13). The end parts (12) of the roll are further mounted, in the area of their axial outer ends, revolvingly and in a radial direction movably on support parts (15), which are separate from the revolving parts of the roll, by means of bearings (14) fitted, in the axial direction of the roll, on the side of the inner side of the end bearings (19).

L'invention concerne un rouleau dérouleur, un rouleau déplisseur ou similaire pour un matériau en bande, ledit rouleau (10) comprenant trois parties reliées les unes aux autres, soit deux parties d'extrémité (12) et une partie médiane (11), lesquelles pivotent les unes par rapport aux autres de sorte que le rouleau (10) puisse être courbé et prenne une forme courbe voulue. La partie médiane (11) du rouleau (10) est conçue pour fonctionner également comme un axe rotatif du rouleau (10), monté rotatif sur des éléments de support au moyen de paliers d'extrémité (19). Les parties d'extrémité (12) du rouleau sont montées, au niveau de leurs extrémités internes radiales, sur la partie médiane (11), au moyen de dispositifs d'articulation (13). De plus, les parties d'extrémité (12) du rouleau sont montées rotatives, au niveau de leurs extrémités extérieures axiales, et mobiles dans le sens radial sur des parties de support (15) qui sont séparées des parties tournantes du rouleau, au moyen de paliers (14) prévus, dans le sens radial du rouleau, sur le côté du côté interne des paliers d'extrémité (19).
