Title
(EN) CONVEYING OF GLASS SHEETS BY MEANS OF CURVED ROLLERS
(FR) CONVOYAGE DE FEUILLES DE VERRE PAR DES ROULEAUX CINTRÉS
Abstract
(EN)
The invention relates to a device for conveying glass sheets travelling one behind the other, comprising at least one roller having an area for conveying glass sheets, said device comprising actuators located on each side of the conveying area, which can curve the roller in its elastic deformation region while allowing it to be rotated about the fixed centres of the cross-sections thereof, the actuators being capable of conferring on the roller, on each side of the conveying area, a dimension and direction giving the roller an asymmetrical shape relative to the plane orthogonal to the roller and equidistant from the actuators.
(FR)
L'invention concerne un dispositif de convoyage de feuilles de verre défilant les unes derrière les autres comprenant au moins un rouleau comprenant une zone de convoyage des feuilles de verre, ledit dispositif comprenant des actionneurs situés de part et d'autre de la zone de convoyage aptes à cintrer le rouleau dans son domaine de déformation élastique tout en le laissant apte à être entrainé en rotation autour des centres fixes de ses sections, les actionneurs étant aptes à donner au rouleau de part et d'autre de la zone de convoyage, une cote et une direction lui donnant une forme asymétrique par rapport au plan lui étant orthogonal et situé à équidistance des actionneurs.
