Abstract
Apparatus and method for forming a stackable container from a container blank. The apparatus generally includes a blank feeder configured to place the blank on a conveyor, an index folder configured to pre-fold a plurality of inner fold-down flaps and an index flap over each of two opposing sidewall flaps of the blank, and a pressure former configured to attach a first leading extension to a leading wall of the blank and a first trailing extension to a trailing wall of the blank, wherein the first leading extension and the first trailing extension are foldably attached at an angle of about 90 degrees to one of the inner fold-down flaps or one of the sidewall flaps. Embodiments of the present the present invention can advantageously provide a reliable approach for forming a container from a blank with relatively fewer folding defects.
