Patent number: 4341055Abstract: A box blank with receptacle and cover sections each with side flaps and end flaps has a hinge panel joining the two sections. A vacuum pickup draws a flat blank from a supply stack to a feed carriage which transfers the blank past sprays that apply glue to the end flaps.
