An apparatus (10) is provided for erecting boxes from blanks (11) having sides panels (13) with three score lines (20, 22 and 24). The apparatus has a base plate (40), two side folding mechanisms (44) and two end folding mechanisms (45). The side folding mechanisms have a proximal plate (51) pivotally mounted to the base plate, an intermediary plate (53) pivotally mounted to the proximal plate, and a distal plate (55) pivotally mounted to the intermediary plate. Linkage (68) coupled to a handle (76) actuates the movement of the proximal, intermediary and distal plates.

An apparatus for erecting boxes with double wall sides and base flaps from blanks having opposite side edges, opposite end edges, and opposite side panels with three spaced apart side score lines, said apparatus comprising; a base having a top surface, oppositely disposed sides and oppositely disposed ends; and two side blank folding mechanisms mounted adjacent said base sides, each of said two side blank folding mechanisms having; a proximal side plate mounted for pivotal movement alongside said base; an intermediary side plate mounted for pivotal movement alongside said proximal side plate; a distal side plate including a catch means mounted for pivotal movement alongside said intermediary side plate; and actuating means for pivoting respectively said proximal side plate toward said base top surface, for pivoting said intermediary side plate toward said base top surface and into overlapped configuration with said proximal side plate, and for pivoting said distal side plate away from said intermediary side plate and said base top surface as said intermediary plate nears said proximal side plate, whereby upon placing the blank upon the base with said side edges captured by the catch means the blank sides are formed through operation of the actuating means by folding the blank along first side score lines as the proximal side plates move toward the base, by folding the blank along second side score lines so as to fold upon the blank portions between the first and second score lines as the intermediary side plates overlap the proximal side plates, and by folding the blank along third score lines to create a base flap as the intermediary side plates pass closely adjacent the base with the blank therebetween.
