ABSTRACT:
An apparatus and method for repeatedly presenting a single, flat, tubular corrugated case, with its leading closure flaps overfolded in open flap position for easy gripping, erection and placement in the case gripper of a case packer device includes the provision of a bottom feed magazine holding a stack of such flats and a plurality of lug chains for advancing each successive individual bottom-most flat through a gateway and along a path up to the operator station of the case packer. Upper folding hooks of exact dimension are arranged to over fold the leading upper, major and minor closure flaps of each successive flat, without contact with the corresponding lower flaps. The leading lower major and minor closure flaps are underfolded further along the path and hold down bars maintain the folds. Sensing means triggers the advance of another flat when the operator removes the flat presented at the operator station.
