PROBLEM TO BE SOLVED: To provide a device for forming tapered boxes fast and surely.SOLUTION: A forming device comprises a female die frame 90 which moves to a forming position while being sucked by a male die 30, comes into contact with a plurality of side pieces of a sheet-like material 9, and bends each of the side pieces from the bottom sheet to form a tapered box 1. In the forming device, the sheet-like material 9 is sucked by suckers 32, 33 on a contact face of the male die 30 at a specified positioning position, and then moved forward for contact with the female die frame 90, where the side pieces of the sheet-like material are bent. When the sheet-like material arrives at the forming position, fixing pieces are brought into contact with and adhered to both end portions of the back side of each side piece to make a tapered box. |
