摘要: 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.
