ABSTRACT:
An apparatus automatically forms a paperboard blank into a container having a double glued side wall construction for providing an enhanced strength to the container. A platen drives the blank through mechanically powered forming rails for an initial folding of the blank into a partially formed container having a bottom, end and side walls, and inside corner supports. A compression plate and folding arms are biased against adhesive portions of the partially formed container for forming a fully formed container having a double glued side wall construction.
