    摘要: An edge portion of one sheet is formed with elongated slots and a raised portion between each slot and the edge of the sheet. The two sheets are then placed together so that an edge portion of the other sheet extends beyond the edge portion of the one sheet. The edge portion of the other sheet is folded back over the edge portion of the one sheet so that the raised portions are flattened and sections of the edge portion between the raised portions and the edge are deformed to fill a gap between the edge of the one sheet and the folded end of the other sheet. Excess deformation is absorbed by deformation of other sections of the edge portion of the one sheet into the slots.
