ABSTRACT:
In a machine for packaging articles in a tubular wrap-around carrier formed from a blank having a pair of walls adjoined together along a fold line and having a pair of article retaining and blank reinforcing flaps disposed astride the fold line, and which includes means for advancing a blank and its associated articles along a predetermined path, a mechanism for engaging and folding the pair of flaps and to fold such flaps inwardly of the carrier. The folding mechanism comprises a pivotal folder `f` adapted to execute a folding movement thereby progressively to enter an aperture in the blank to fold the flaps and to retract therefrom during feed movement of the blank and the pivotal folder together through a folding station of the machine.
