Title
(EN) APPARATUS FOR AXIALLY POSITIONING THE ROLL SHELL IN A HYDROSTATICALLY LOADED CONTROLLED DEFLECTION ROLL
(FR) APPAREIL POUR POSITIONNER DANS LE SENS AXIAL LA VIROLE DE CYLINDRE DANS UN CYLINDRE A DEVIATION CONTROLEE CHARGE DE MANIERE HYDROSTATIQUE
Abstract
(EN)
A controlled deflection roll (1) has a roll shell (2) which is hydrostatically radially supported by internally disposed hydrostatic shoes (3, 9). In order to axially position the roll shell (2), a mechanical locating link (23) is provided which is disposed externally of the roll shell (2). The link is coupled at one end to an element attached to the roll shell (2), and is coupled at an opposite end to a fixed support, such as a floor stand (7). The end of the roll at which the locating link (23) is disposed is thus axially fixed, while the opposite end of the roll remains free to float. The locating link (23) can be connected to an oscillator to oscillate the roll shell (2) axially during operation so as to distribute any non-uniformities in the roll shell (2) and thus to mitigate their effect on the sheet.
(FR)
Un cylindre (1) à déviation contrôlée comporte une virole (2) qui est supportée de manière hydrostatique, dans le sens radial, par des patins hydrostatiques (3, 9) disposés à l'intérieur. Afin de positionner la virole (2) dans le sens axial, une liaison de positionnement mécanique (23) est prévue à l'extérieur de la virole (2) du cylindre. La liaison est couplée, à une extrémité, à un élément fixé à la virole (2), et à l'autre extrémité à un support fixe, tel qu'un pied (7). L'extrémité du cylindre au niveau de laquelle la liaison de positionnement (23) est placée est ainsi fixée, dans le sens axial, tandis que l'extrémité opposée du cylindre peut flotter librement. La liaison de positionnement (23) peut être reliée à un oscillateur pour assurer l'oscillation de la virole (2) du cylindre, dans le sens axial, en service, de manière à répartir toute irrégularité dans la virole (2) du cylindre et àen atténuer les effets sur la feuille.
