Abstract
An apparatus is provided for folding a sheet (1) into a folder provided with a spine and at least one cover. In the portion of the sheet forming the spine of the folder after folding, there is applied a bead (2) of binder for binding sheets of paper, inserted in the ready folder, to the inside of the spine. The sheet is advanced with the bead parallel to the advancing direction via a rail (14) guiding the bead to folding and back-up means implemented as rollers (15, 16, 19, 20), for folding the cover side against the inside of the spine along a line situated closely adjacent and parallel to the bead.
