Title
(EN) COMBINED GLASS SHEET BENDING AND QUENCH STATION
(FR) STATION DE PLIAGE ET DE TREMPE COMBINES POUR FEUILLES DE VERRE
Abstract
(EN)
A combined bending and quench station (30) disclosed comprises a roller conveyor (36) proximate a glass heating furnace (32). The roller conveyor (36) includes elongated rolls (38) spaced from each other in a parallel relationship. A plurality of molds (40) are located generally between the rolls (38). Each mold (40) has a glass engagement surface (42). An actuator (48) engages the glass engagement surfaces (42) with the heated glass sheet (34) to provide bending. Upper and lower blastheads (44, 46) supply quenching gas that impinges with the bent glass sheet (34) while engaged with the molds (40) to fix the shape and provide tempering of the bent glass sheet.
(FR)
La station de pliage et de trempe combinés décrite (30) comprend un transporteur à rouleaux (36) placé à proximité d'un four (32) de chauffage du verre. Le transporteur à rouleaux (36) comporte des cylindres allongés (38) espacés les uns des autres en parallèle. Plusieurs moules (40) sont généralement disposés entre les cylindres (38). Chaque moule (40) présente une surface (42) d'engagement du verre. Un actuateur (48) place les surfaces (42) d'engagement du verre en prise avec la feuille de verre chauffée (340 pour effectuer l'opération de pliage. Des têtes de soufflage supérieure et inférieure (44, 46) fournissent du gaz de trempe qui heurte la feuille de verre pliée (34) pendant qu'elle se trouve en prise avec les moules (40) afin de fixer la forme et d'assurer la trempe de la feuille de verre pliée.
