ABSTRACT:
Flap folding plates are provided for use with a carton taping machine, the plates normally being disposed in upright orientation and maintained such by bias applied thereto. Further the plates are arranged so that the top corner structure at the sides of the carton strike the plates to cause the plates to pivot rearwardly in folding movement against the carton side flaps thereby absorbing at the said corner structures the force that might otherwise be transmitted to the front edges of the upright side flaps which could result in tearing or ripping of the side flaps where said flaps are joined to associated side walls.
