Abstract
Apparatus for forming a denesting lip in paperboard containers by folding, heating, and sealing or tacking a side extension flap to form a denesting lip for nested stacks of such containers. The denesting apparatus includes a pair of pressure pads which guide the paperboard container onto the apparatus and prevent the container from sliding off the apparatus while the denesting operation is performed. The apparatus also includes a multiplanar mandrel pad for forming a bottom closure that is flat on its exterior surface.
