Manufacture of cambered glass sheets without the need for pinching mechanism at the outlet of the cambering machine, notably for motor vehicle windows

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.
