A method for manufacturing a screen cylinder and a screen cylinder with screen wires (2) in the axial direction of the screen cylinder (1) set at predefined intervals into a cylindrical screen surface and fastened to support rods (3), and end rings (5) are arranged at the ends of the screen cylinder (1). At least one end ring (5) is mounted at one end of the screen cylinder (1) in such a manner that the end ring is arranged to at least one support rod (3) at the ends of the screen wires (2) or closest to the ends of the screen wires (2) without fastening the end ring (5) to the screen wires (2). When installing the end ring (5), a shrink fit is formed between the end ring (5) and support rod (3), wherein the end ring (5) is arranged to press the support rod (3) substantially perpendicular to the axis of the screen cylinder (1).

L'invention concerne un procédé permettant de produire un cylindre de tamis, et un cylindre de tamis comprenant des câbles (2) de tamis installés à des intervalles prédéfinis dans une surface de tamis cylindrique, dans la direction axiale du cylindre (1), et fixés sur des tiges (3) de support, et des anneaux (5) d'extrémité disposés aux extrémités du cylindre de tamis (1). Au moins un anneau (5) d'extrémité est monté à une extrémité du cylindre de tamis (1) de manière à recouvrir au moins une tige de support (3) aux extrémités des câbles (2) de tamis, ou à proximité immédiate des extrémités de câbles (2) de tamis, sans assemblage de l'anneau (5) d'extrémité avec les câbles (2) du tamis. Lors de la mise en place de l'anneau (5) d'extrémité, l'anneau (5) d'extrémité et la tige (3) de support sont assemblés par calage à retrait, de telle manière que l'anneau (5) d'extrémité exerce une pression sur la tige (3) de support dans une direction sensiblement perpendiculaire à l'axe du cylindre de tamis (1).
