An improved method of gluing a package in an in-line packaging machine. The package is of the type having a plurality of leading and trailing end flaps which are glued to be together during the packaging process. The novel method comprises in part providing at least two glue nozzles in the line of the packaging machine direction with one glue nozzle facing downwardly and upstream while the other glue nozzle faces downwardly and downstream so that the glue is applied to a pair of the end flaps by one nozzle in an upwardly direction and by the other nozzle in a downwardly direction as the package is moved through the packaging machine past the glue nozzles. Subsequently thereafter, the other pair of end flaps are turned inwardly and are held in position after being glued until the glue sets. The four flaps of the package are turned inwardly by a first and a second flap closing means. |
