PURPOSE: To prevent breaking of the load by supporting and reversing a box advanced by an outer guide, an inner guide and a side guide to lessen the trembling of the box, and pressing the boxed articles to be supported by a pressing plate.

CONSTITUTION: The upper end edge portion 1a of a box 1, the upper portion of which is opened, is brought into slidable contact with a guide 5 forming a circular arc of the outer periphery of a perpendicular semicircular track to be supported, and a plurality of pressing plates 13 for pressing the boxed articles to be supported are disposed along the guide 5 in such a manner that the forward ends are projected inward. A plurality of inner guides 6 forming an inside circular arc of the perpendicular semicircular track are disposed along the direction of forwarding the box, so as to press and support the lower end edge portion 1b. A rotary roll 20 brought into contact with both end edge portions is mounted at the inlet portion of the perpendicular semicircular track, and further both side portions of the box advancing in the perpendicular semicircular track are pressed and supported by a side guide 7. In this arrangement, the boxed articles can be automatically reversed without damages.
