PURPOSE:To improve the working efficiency to a large extent by unnecessitating the diaphragm of a fusing furnace by a method wherein a back protection sheet is made larger than the titled panel in outer shape, the outer periphery of which sheet is then held by means of the flange part of the furnace. CONSTITUTION:The laminated body 24 with cover glass, PVB (polyvinyl butiral), solar battery element, and PVB laminated in this order is placed in the fusing furnace 21. Further, the back protection sheet 25 large enough to cover the furnace to the flange part is mounted thereon. On closing the lid 22 of the furnace 21 in this state, two chambers A' and B' split by means of the sheet 25 are formed. |
