PROBLEM TO BE SOLVED: To provide a jumping seal capable of smoothly carrying out a raw material sheet feeding action and blank material separating action in punching processing.SOLUTION: A jumping seal 15 is pasted near a ruled line groove mold material 11 on a receiving plate 10 to which the ruled line groove mold material 11 having a ruled line groove 11a for forming a folding line 4a on a blank material 4 cut out in a predetermined shape from a raw material sheet 3 is pasted. A raised shape portion 15a showing elastic repulsion force in a raised shape than an outer peripheral edge is formed to flip up the raw material sheet 3 transported on the receiving plate 10 by the raised shape portion 15a, and push out the blank material 4 meshed with the ruled line groove 11a by the raised shape portion 15a.SELECTED DRAWING: Figure 1 |
