PROBLEM TO BE SOLVED: To automatically and effectively remove scrap from a blanked sheet. SOLUTION: This device is provided with a suction means 8 to suck a plurality of product sections 2... arranged at specified positions of a blanked sheet body 1 and a scrap section 3 by negative pressure and a scrap separating means 9 to separate the scrap section 3 from the sheet body 1 by releasing the suction of the scrap section 3 by negative pressure while maintaining the negative pressure of the scrap section 3. The scrap separating means 9 is provided with a pair of holding plates 25 and 25 having a plurality of air holes 24... penetrating the holding plates 25 and 25 from both sides of each plate with the holding plates 25 and 25 placed one upon the other and an air supply section 26 to supply air to the air holes 24 of the holding plates 25 and 25. In addition, the scrap separating means 9 is constituted in such a way that with only the product section 2 comprising the sheet body 1 from which the scrap section 3 is removed held by a pair of the holding plates 25 and 25 at a specified position and with the air hole 24 at the position corresponding to the product section 2 at a specified position closed, air is sent to release the suction of the scrap section 3 by negative pressure by the air passed through the air holes 24... at the positions not corresponding to the product sections 2....
