Abstract
A separator sheet is formed of a plastic material and has a number of ribs formed on one side thereof. The ribs extend in the direction in which the separator sheet is fed. The sheet is overlaid with a glass mat, and a laminated member obtained thereby is moved into the region between a pair of driving rolls. After being sandwiched by the driving rolls, the laminated member is fed into an envelope apparatus. In an adhesive coating step, a hot melt adhesive is coated on one side of the glass mat. The adhesive is coated at portions C corresponding to the base sections between the ribs of the sheet, in such a manner that the coated adhesive forms a line extending in the longitudinal direction of the glass mat. In a stacking step, the sheet and the glass mat are stacked one upon the other. In the pressing step, the laminated member is sandwiched between the driving rolls, and the adhesive-coated portions of the glass mat are tightly pressed by the ribs provided on the circumferential surface of the driving roll. The ribs extend in the circumferential direction of the roll and are located at positions corresponding to the adhesive-coated portions.
