ABSTRACT:
In a non-round container forming machine having a device for receiving and delivering flat container wall blanks to a wrapping station, at which the blanks are wrapped around a non-round mandrel. The non-round mandrel has a front end facing the blank. The blank is aligned substantially tangential to the mandrel when delivered to the wrapping station. A wing slide assembly, within the wrapping station, moves linearly along opposite sides of the mandrel in a wrapping direction substantially perpendicular to the blank to fold the blank along opposite sides of the mandrel. A forward wing clamp assembly, within the wrapping station, is mounted proximate a rear end of the mandrel to move pivotally to engage and direct outermost portions of opposite ends of the blank in an overlapping relation against the mandrel to form a side seam. The containers are removed from the mandrel with an extractor plate which physically engages the containers upper edge.
