Abstract
A belt type box blank folding machine including bar folder assemblies on a downstream end thereof for engaging partially folded substantially upstanding outer panels on the blanks and folding them downward against inner panels of the blanks. The bar folders are arranged to pivot from an upright position, in engagement with the upstanding panels, to a horizontal position and to simultaneously reciprocate along the path of blank travel to provide maximum engagement with the outer panels during folding thereof. The bar folders are parallel with the fold line of the outer panels during folding thereby preventing twisting of the panels and locking of the leading flaps of the outer panels against the inner panels.
