Abstract
Disclosed is a sheet stack manufacturing process. At first, a plurality of band sheets are fed. Each band sheet is folded at least once along a longitudinal direction thereof at a first folding step, to form folded bands. Then, each folded band is folded along the longitudinal direction at a second folding step to have at least three fold lines by the first and second folding steps and to sandwich a portion of at least one of an overlying sheet and an underlying sheet thereof, thereby to form a band-shaped sheet stack in which a plurality of sheets are combined with one another so as to be stacked on one another. The band-shaped sheet stack is cut to a predetermined length to be separated into individual sheet stacks.
