摘要

"PRESS BENDING STATION FOR GLASS BENDING, AND TEMPLATE IN A PRESS BENDING STATION FOR GLASS BENDING". It is a press bending station that includes an annular mold (5) and a full face mold (6). Holes (10), selectively connected to a negative pressure source, are disposed in portions of the full-face mold (6) that are determined by the annular mold configuration when the annular mold contacts a heated glass sheet (2). during the press bending process. The sheet (2) is sucked by negative pressure through the holes (10) towards the full face mold (6) and thus acquires its shape. Positive pressure can be selectively applied to the holes (10) for detaching the sheet (2). According to the invention at least some of the holes (10) are arranged in at least one slot (11) formed in the molding face of the full face mold. The grooves (11) according to the invention considerably accelerate the negative pressure removal of air between the molding face of the full face mold (6) and the glass sheet (2) intended to be curved, thereby improving the process. bending by pressing.
