MANUFACTURING PROCESS OF RECURVED GLASS LEAVES, GLASS LEAF RECURVING MACHINE, AND RECURVED GLASS LEAVES

摘要

The manufacture of cambered glass sheets consists of: (a) bringing glass sheets to their softening temperature; (b) defiling them on a conformation bed (6) made up of some rollers (7) allowing their advancement, arranged according to a trajectory with the profile of an arc of a circle; (c) progressively forming the sheets in a shaping zone (5); (d) tempering or cooling the sheets in a second zone (8) up to the outlet of the conformation bed; (e) recuperating the cambered glass sheets thus obtained. The conformation bed is constituted with the profile extending itself following an arc of a circle of more than 90[deg] and the displacement of the tempered glass sheets at the outlet is assured in a direction opposite to that in which the sheets are fed into the conformation bed. Independent claims are also included for: (a) a machine for the cambering of glass sheets by this method; (b) the cambered glass sheets obtained by this method.
