An automatic carton box fabricating apparatus. The apparatus has upper and lower endless feed belts conveying blanks supplied one by one therebetween. The endless belts support the lower portions of the parts of the blanks inside the creases on both side walls thereof. Guide members press the upper portions of the parts of both side walls similarly inside the creases thereof, and folding belts fold the portions of both side walls outside the creases thereof over the guide members during the advancement of the blank. A pressing plate presses down the bottom of the blank after the blank stops in a stopping position. At this point the side walls of the blank have been folded double by the guide members and folding belts. Guide rods bending upwards pieces provided on the ends of both side walls when the blank is pressed down by the pressing plate. Guide members also bending upwards both side walls after each of the pieces is bent upwards similarly during descent of the blank, and guide members also bend upwards both end walls after both side walls are bent upwards during descending of the blank plate. A receiving plate receives the carton made from the blank, supporting the bottom of the blank as it descends under the force of the pressing plate before the pressing plate reaches its lower limit of movement, and a delivery device carries the carton away to a desired place. |
