Abstract

PURPOSE: To prevent the layer between blanks from shifting and to separate the blanks by every job by a method wherein they are pressed front and rear of the perforation and cut at the perforation where stress is concentrated.
CONSTITUTION: As a separator 13 falls further, the top 13a of the separator 13 comes in contact with a blank 5 and the blank 5 begins to be strained at the contact part. However, since the top 13a is suitably round, the blank does not break at this part. Therefore, on the straight perforation 5a made over the whole width of the blank rectangular to the running direction of the blank 5, strain is given from the part nearest to three tops 13a. The perforation 5a full of strain begins to be split by notch effect due to concentration of stress, continues to be split easily by the separator 13 with the fall dowm to the lower dead point of the link mechanism 15 and at last the blank 5 is separated between the jobs.
