  • Patent number: 3969918
    Abstract: A method and apparatus are provided for blanking from coil stock blanks to be supplied to and formed by a transfer press having a transfer feed line through the transfer press along which the blanks are fed. The coil stock is fed along a coil stock feed line which is below the transfer feed line of the transfer press over a male blanking punch. A female blanking die is lowered from above the transfer feed line of the press over the male blanking punch for blanking blanks from the coil stock. The blanks so formed are elevated from the male blanking punch to the transfer feed line of the press for transfer thereof along the transfer feed line. The scrap of the coil stock resulting from such blanking operation is discharged along the coil stock feed line below the transfer feed line of the press so as not to interfere with the transfer of the blanks along the transfer feed line of the press.
