Zusammenfassung:	Bag folding assembly for folding a paper bag opening comprising, first 102 and second 104 jaw assemblies centred along an axis 106, each jaw 102 104 transitions between open and closed configurations to grip a region of a paper bag. The jaw assemblies are arranged to face each other and rotate about axis 106 to fold the paper bag. The jaw assemblies may move away from one another during rotation. The first and second jaws 102 104 may move with respect to a level change axis 318 perpendicular to the axis 106. A mouth preparation finger assembly comprising a plurality of fingers may prepare the mouth region of the bag for grasping by the bag folding assembly. A method of closing a paper bag using a mouth preparation finger assembly, and folding the bag using a bag folding assembly, is disclosed.
