Claim 7:
8. A method for separating blanks, the method comprising:
using a blank separating device to separate the blanks, the blank separating device comprising an upper blank separating module and a lower blank separating module, the lower blank separating module comprising at least three supporting elements, each of the at least three supporting elements comprising at least one supporting surface for bracing blanks or scrap pieces, and at least two supporting elements of the at least three supporting elements being configured as supporting elements of a lower separating tool, wherein:
the at least two supporting elements of the lower separating tool are each configured to be arranged at least in three positions in a vertical direction relative to a portion of the lower blank separating module,
the upper blank separating module includes at least two contact surfaces having a first distance from a carrier plate of the upper blank separating module, at least one of the at least two contact surfaces being moveable relative to the carrier plate and at least one other one of the at least two contact surfaces during a separation process, and
in a separating position of the lower blank separating module, the at least two supporting elements of the lower separating tool are arranged at respective positions of the three positions so that, during a separation process, a position of at least one of the at least two supporting elements causes the at least one of the at least two contact surfaces of the upper blank separating module to be temporarily displaced from the first distance to a second distance with respect to the carrier plate, while the position of at least one other one of the at least two supporting elements allows the at least one other one of the at least two contact surfaces of the upper blank separating module to remain at the first distance with respect to the carrier plate,
wherein, at least in the separating position, the lower blank separating module has a relief including three planes through the supporting surfaces which are arranged so as to differ in the vertical direction.
