Title
(EN) CALENDERING CONTROL SYSTEM
(FR) SYSTEME DE COMMANDE DE CALANDRAGE
Abstract
(EN)
A system for controlling calendering roll diameters in continuous sheetmaking systems includes profile actuators (27) spaced from one another at generally decreasing distances (D1>D2>D3>...>DN) along a plenum (25) which extends from edge to edge of the sheet. The largest spacing (D1) between nozzles is at locations corresponding to the center of the sheet.
(FR)
Un système de commande des diamètres de rouleaux de calandrage dans des systèmes de fabrication continue de feuilles, comprend des actuateurs (27) profilés espacés l'un de l'autre à des distances (D1>D2>D3>...>DN) décroissantes, le long d'un plénum (25) s'étendant d'un bord à l'autre de la feuille. L'écartement (D1) le plus grand entre les ajutages, se trouve à des emplacements correspondant au centre de la feuille.
