ABSTRACT:
A bag folding apparatus comprises an in-feed mechanism, a rotatable spindle, a stripper, and a pair of folding nip rollers. The stripper is slidably mounted on the spindle and is movable between a retracted position and a forward position. To fold a bag segment having one or more bags connected by perforations, the in-feed mechanism first feeds the bag segment to the rotatable spindle while the stripper is disposed in the retracted position. Rotation of the spindle causes the bag segment to be wound about the spindle. After the bag segment is wound about the rotating spindle, the stripper is moved from the retracted position to the forward position. Movement of the stripper from the retracted position to the forward position strips the wound bag segment from the spindle. With the spindle positioned adjacent to the pair of nip rollers, the stripped bag segment is fed between the pair of nip rollers. The pair of nip rollers flatten the stripped bag segment so that the bag segment is effectively folded.
