Method for the production of curved glass sheets
摘要:
A method of and a device for curving glass sheets preheated to curving temperature operate by passage of the glass sheets simultaneously over a principal shaping bed having a longitudinal trajectory which is substantially circular or substantially a cone of revolution, and one or more secondary shaping beds, the generatrices of which are inclined relative to those of the principal bed. The invention is applicable, notably, to the production of automobile panes having angled corners.
