A slide removes the blank released from the blank column out of the pile. The separating members comprise an engaging ledge supporting the blank column and a row of needles fixing by piercing the blank column next to the lowermost of the blanks at the end face, both of the separating members are suspended by means of angle members on different carrying rods with the same pivot point and swing in and out alternately by means of a common driving means.
