摘要

There is disclosed a wrapping machine for use in a packaging system, which comprises a conveyor for transporting a U-shaped case adapted to wrap an article and formed in such a way that front and rear flaps of a flat sheet are folded toward the front and rear sides of the article, an inner flap folding mechanism for folding side flaps of the sheet toward both sides of the article while the case is transported, a gluing mechanism for applying glue to the outer surfaces of the inner flaps, and a side flap fold/press mechanism having guide plates actuated selectively by a cam drive mechanism and hydraulic cylinders and adapted to fold and press the side flaps toward the glue bearing surfaces of the inner flaps.
