1. A method for providing blanks from a fibre web in a sequence predefined for a layer-by-layer construction of a workpiece from the blanks, comprising:
subdividing the fibre web into a plurality of removal regions, each having a sequence number according to a relative position on the fibre web, wherein at least some of the removal regions overlap with a prior one of the removal regions having a lower sequence number and with a subsequent one of the removal regions having a higher sequence number;
removing each of the blanks from one of the plurality of removal regions of the fibre web in an order based on the sequence numbers of the removal regions;
depositing each of the blanks per removal region in at least one of a plurality of deposit elements;
removing each of the blanks from the deposit elements in accordance with a sequence predefined by the layer-by-layer construction of the workpiece, wherein the blanks that are individually removed from the removal regions are stacked on top of one another in the deposit elements in each case in a sequence that corresponds to a layering sequence of the blanks for constructing the workpiece layer-by-layer, and wherein the blanks for a workpiece that are stacked in the deposit elements are successively removed individually from the deposit elements in a sequence which is reversed with respect to the layering sequence of the blanks for constructing the workpiece layer-by-layer;
stacking the blanks on top of one another in a storage element;
successively removing the blanks from the storage element in the layering sequence of the blanks for constructing the workpiece layer-by-layer; and
inserting the blanks into a mould for producing the workpiece.
