Automated apparatus for forming paperboard packaging from an integral paperboard blank includes a blade for gathering a central portion of the paperboard blank, causing the width of the blank to contract. A reciprocating mandrel rams the blank into a hollow tubular former having an opening of reduced size, causing portions of the blank to form side walls properly positioned with respect to a floor portion of the blank. Pistons within the mandrel apply pressure to overlapping portions of the formed blank, to seal those portions together.
n appareil automatisé pour former un emballage de carton à partir d'un carton intégral non taillé comprend une lame pour amener une partie centrale du carton non taillé, causant sa contraction en largeur. Un mandrin à mouvement alternatif pousse le carton non taillé dans un moule tubulaire creux ayant une ouverture de dimension réduite, ce qui force des parties du carton à former des parois latérales bien situées par rapport à une autre partie formant le plancher du carton. Des pistons à l'intérieur du mandrin exercent une pression sur des parties chevauchantes du carton ouvré pour coller ces parties les unes aux autres.
