It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.

Abstract

L'invention porte sur un appareil de traitement de feuilles de verre, lequel appareil comprend un segment de monorail et un segment à double rail, qui sont chacun conçus de façon à soutenir un poids d'une feuille de verre. D'autres modes de réalisation de l'invention portent sur des procédés de traitement de feuilles de verre, lesquels procédés comprennent l'étape de transport d'une feuille de verre suspendue le long d'une direction de transport de feuille de verre tout en changeant un angle entre une surface principale de la feuille de verre et la direction de transport de feuille de verre. D'autres exemples de l'invention portent sur des procédés, qui mettent en œuvre le transport de la feuille de verre suspendue le long d'une première direction de transport de feuille de verre tandis qu'une surface principale de la feuille de verre est à un premier angle par rapport à la première direction de transport de feuille de verre ; puis le transport de la feuille de verre suspendue le long d'une seconde direction de transport de feuille de verre tandis qu'une surface principale de la feuille de verre est à un second angle par rapport à la seconde direction de transport de feuille de verre.
