<p>PURPOSE:To prevent a crack or the like of a sealing surface and improve the reclamation rate, by maintaining the temperature of the glass of either a panel or a funnel almost constant while applying the heat cycle only to the glass of the other side. CONSTITUTION:While heat insulating cover 7 to cover the whole body of a panel 1a is formed to cover from the panel sealing surface to the whole body of the panel 1a side, the water 9 for the heat cycle from nozzles 8 at the upper side of a funnel 1c is flown over the whole body of the funnel 1c in order. In this case, in heat insulating cover 7 is made to cover partially the funnel 1c side sealing surface a cross the panel sealing surface, that the water 9 for the heat cycle is never applied to the panel 1a side.</p> |
