PROBLEM TO BE SOLVED: To assemble a box by folding a prescribed pattern paper sheet promptly and correctly. SOLUTION: A bonding member 3 for bonding the side margin of the middle part of a pattern paper sheet to be mounted and a clamp member 4 are installed in the upper part of a frame 1. A pair of the first right and left bending members 7 for folding the side piece of the pattern paper sheet upward is installed rotation-movably on the first support shaft 6 which extends in the front-rear direction of the frame 1, and both the first bending members 7 are connected to each other interlockably by link members 8a, 8b. The second bending member 13 for folding the folding piece of the middle part of the pattern paper sheet is installed on the second support shaft 12 which extends in the right-left direction of the frame 1. A cam member 10 which is supported by a cam shaft 9 is set between the first and second bending members 7, 13, and the second bending member 13 is pushed up through the cam member 10 to rotate and move in the rising direction when the first bending member 7 rotates and moves in the rising direction. |
