Title (EN) HEATED GLASS SHEET TOPSIDE SUPPORT DEVICE
(FR) SYSTEME DE SUPPORT PAR LE DESSUS POUR FEUILLE DE VERRE CHAUFFE
Abstract:
(EN) A heated glass sheet topside support device (22, 22', 22a, 22a') is disclosed as including horizontally extending lower and upper plates (38, 46) connected by a set of vertically extending passage members embodied by tubes (54) or plate members (54a) to define passages (55, 55a, 55a'). The support device also includes first and second manifolds (56, 58) for supplying pressurized gas and a vacuum through first and second sets of holes (42, 42a, 42a'; 44, 44a, 44a') in the lower plate so as to thereby support a heated glass sheet below the lower plate without any engagement. In one construction, the pressurized gas is supplied through a chamber (48, 48a) between the plates through a set of shorter tubes (80, 80a) mounted within the first set of holes (42, 42a) in the lower plate (38, 38a), and a vacuum is drawn from the upper side of the upper plate (46, 46a) through the holes (52, 52a) therein and through the passages (55, 55a) and the second set of holes (44, 44a).
(FR) Système de support par le dessus pour feuille de verre chauffé (22, 22', 22a, 22a') comprenant des plaques supérieure et inférieure (38, 46) s'étendant horizontalement, reliées par un ensemble d'éléments de passage s'étendant verticalement se présentant sous forme de tubes (54) ou d'éléments de plaques (54a) qui définissent des passages (55, 55a, 55a'). Le système de support comprend également des distributeurs primaire et secondaire (56, 58) qui fournissent du gaz sous pression et du vide via deux séries d'orifices (42, 42a, 42'a, 44, 44a, 44a') situées dans la plaque inférieurer et qui permettent de supporter une feuille de verre chauffée sous la plaque inférieure sans être directement en prise. Dans une construction, le gaz pressurisé est alimenté par une chambre (48, 48a) située entre les plaques, via une série de tubes plus courts (80, 80a) montés à l'intérieur de la première série d'orifices (42, 42a) située dans la plaque inférieure (38, 38a), et le vide est extrait du côté supérieur de la plaque supérieure (46, 46a) via les orifices (52, 52a) qu'elle comporte et via les passages (55, 55a) et la deuxième série d'orifices (44, 44a).
