PROBLEM TO BE SOLVED: To supply a layered product of a sheet and a glass mat efficiently to an envelope device by accelerating solidification of a bonding agent. SOLUTION: A plurality of ribs 1b are parallelly formed in one surface of a sheet 1 for a separator, in one surface of this sheet, a glass mat 2 is piled together to be layered, this layered product 3, while it is interposed between a pair of drive rollers 24, 25, is fed into an envelope device to be supplied. Here, before piling together the sheet and the glass mat, in its one surface and in a part corresponding to a plurality of base parts 1b mutually between the sheet and the rib, a hot metal type bonding agent is applied, in a peripheral surface of one drive roller 25, a plurality of ribs 25a opposed to a part applied with the bonding agent are provided, when the layered product of the sheet and the glass mat is interposed between a pair of the drive rollers, the sheet and the glass mat in a part applying the bonding agent are brought into press contact through the rib 25a. |
