ABSTRACT:
A box-flap folding device which includes a support for folded side flaps of the box during the folding operation of front and rear flaps. The support is so constructed as to prevent the folded side flaps from getting unfolded and not to interfere with the folding operation of the front and rear flaps, resulting in that all the flaps of the box can be folded smoothly without being bent or broken.
