A set of sheets delivered seriatim from a copier/duplicator or other source are advanced along a sheet path leading from an input station to an assembly station where a booklet is formed. As a sheet is moved along the path a line of adhesive is applied to one surface of the sheet adjacent to one side edge of the sheet. In the assembly station the sheets are jogged to align the sheets of the set and then pressure is applied to the sheets over the line of adhesive. When the entire set has been bound together into a booklet, the booklet is removed from the assembly station and delivered to an output station, such as a tote tray.
