Abstract
The batch manufacturing of laminated cells whose spacing is kept constant by means of spacers (11) of diameter d, comprises the steps of forming a first line on a substrate (1), with a hot melt adhesive material for the sealing frames (3) and junction portions (5) between the holes (6) of spacing e and a second line (7) closed at one end (8) to create a filling channel (9), said lines having a constant cross-section So and a height h; depositing the spacers (11) over the substrate (1) and close to the holes (6), destructible or deformable spacers (12) of diameter D such that h>D>d; sealing a second flat deformable substrate (2) with a reduced application of pressure above the holes (6); filling all the cells; exerting a second pressure equal to or greater than the first and heating the zones above the holes to a temperature equal to or greater than that of the hot melt adhesive material; and cutting out each cell.
