A record and an open ended bag are conveyed along different paths at right angles to each other, but in the same plane, insertion of the record into the bag taking place at the intersection of the paths. As the bag is being conveyed it passes between a pair of rotatable eccentric suction rollers which grip the front and back faces of the bag respectively and cause the bag to be opened as the surfaces of the rollers move apart, due to the rotation of the rollers.
