Abstract
A device for testing tempered glass plates using a heat-up phase, a holding phase and a cooling phase has at least one chamber in which the glass plates which are to be tested, standing in harp racks, are placed. The device has a fan with a heating and cooling elements which is connected on the intake side to the top end of the chamber and on the pressure side to the bottom end of the chamber underneath a perforated bottom which borders the chamber to the bottom. The perforated bottom can be a stationary, sloped bottom or a conveyor element with a perforated transport belt. Next to the bottom is a discharge channel for glass pellets which form when a glass plate breaks during the test cycle.
Claims18
Device for testing of tempered glass plates with at least one chamber (4, 6, 8;
- 54, 56) for accommodating the tempered glass plates to be tested during the heating, holding and cooling phase, characterized in that the chamber (4, 6, 8;
- 54, 56) has a perforated bottom (16, 66) so that the heated/cooled fluid which is used to heat/cool the glass plates can be routed through this bottom (16, 66) into the chamber (4, 6, 8;
- 54, 56).
