Abstract
A sheet folder is convertible to a booklet maker by mounting a stapling and sheet guide unit at the inlet side of the folder. The stapling and sheet guide unit has a pair of laterally aligned staplers above a sheet guide which includes holders for engaging the stack of sheets along their opposite side edges and a retractable front stop engaging the leading edge of the stack of sheets to be stapled. A vibratory jogger on one of the holders aligns the edges of the sheets in the stack. After the stack of sheets is stapled, the front stop is retracted and a kicker plate strikes the stapled set of sheets from below, causing the stapled set of sheets to slide down into the folder. The folder has rollers which advance the leading edge of the stapled set of sheets against a stop and then continue to pull the stapled set of sheets, causing its stapled centerline to fold into a fold gap between rollers. The size of this fold gap is selectively adjustable.
