Automatic carton packing machine

摘要

A folding device for imparting a folding habit to the opened top of a carton comprises a frame which is connected to a shaft for moving the frame upwardly and downwardly. A pair of squeezing plates are secured to the frame. The squeezing plates have oppositely tapering lower portions and parallel upper portions. A deforming plate having oblique edges is movable between the upper portions of the squeezing plates and is connected to the frame by a resilient mounting which permits upward relative movement of the deforming plate with respect to the squeezing plates. The lower edge of the deforming plate includes upwardly and outwardly extending edges for spreading opposite edges of a carton. The squeezing plates are used to squeeze opposite sides of the carton together so that the carton top can ultimately be closed.
