A combination folder and sealer machine is much more compact than prior separate and individual folder and sealer machines. The combination folder and sealer machine comprises a folder station that grips a folded sheet simultaneously with a sealer station downstream of the folder station. The sheet is thus under complete control as it is propelled from the folder station to the sealer station, thereby eliminating any skewing that might occur between the two stations. Folding rollers at the folder station are biased toward each other, but the sealing rollers at the sealing station are biased away from each other. A single motor drives the folder and sealer stations as well as a feeder station. Drive trains for the sealer and folder stations are on opposite sides of the machine. A bearing mechanism enables any folding roller to be removed from the machine without removing any other roller and without affecting the machine side walls.
