摘要：The invention relates to a method for crowning at least one sheet of glass (3),comprising a step for slumping the glass by means of gravity, bringing the central part ofsaid at least one sheet (3) into contact with a male form (2), by bringing the male formclose to a female counter-form (4) which supports said sheet, said male form (2) beingarranged above said female counter-form (4) with the possibility of a vertical
displacement of one relative to the other in a crowning cell, then a pressing step for theglass in the peripheral region thereof between the male form (2) and the female form (4),a suction step for the glass against the male form (2) whilst maintaining the pressing,then stopping the pressing by withdrawing the male form from the female counter formand a stage for cooling the glass outside the crowning cell. According to the invention,crowning can be produced with strong curves in two orthogonal directions withoutmarking the glass.
