The device is characterized in that a placing system is mounted downstream of the cutting apparatus for orderly sorting of the blanks. ## Claims ### Claim 1 A device for producing blanks from a product web, the device comprising: rotary cutting means; means, disposed downstream of said rotary cutting means, for sorting and stacking the blanks, said means for sorting and stacking comprising a delivery nest defining steps onto which the blanks are disposed at differing vertical and horizontal positions, wherein adjacent steps have a mutual vertical separation which is sufficiently large as to permit horizontal displacement of at least one blank from a higher lying step onto at least one blank disposed on an adjacent lower lying step; means, disposed between said cutting means and said sorting and stacking means, for determining faulty blanks and for directly removing said faulty blanks prior to delivery to said sorting and stacking means; and waste means accepting the faulty blanks from said determining and removing means. ### Claim 2 (depends on 1) The device of claim 1, wherein a transfer system or a suction belt means is disposed downstream of said rotary cutting means. ### Claim 3 (depends on 2) The device of claim 2, wherein the blanks are separated from a waste strip or a waste grid at said suction belt means. ### Claim 4 (depends on 2) The device of claim 2, wherein an arbitrary number of blanks is disposed on said suction belt means, said determining and removing means comprising an optical test device disposed above said suction belt means for detecting printing faults or missing blanks. ### Claim 5 (depends on 2) The device of claim 2, further comprising a suction cup belt disposed downstream of said cutting means for receiving the blanks from said suction belt means. ### Claim 6 (depends on 5) The device of claim 5, wherein said suction cup belt comprises individual suction cups. ### Claim 7 (depends on 6) The device of claim 6, wherein said suction cups on said suction cup belt have same mutual separations as the blanks along the product web. ### Claim 8 (depends on 6) The device of claim 6, wherein said suction cups on said suction cup belt have different mutual separations than the blanks along the product web. ### Claim 9 (depends on 6) The device of claim 6, wherein said suction cups are disposed on said suction cup belt at variable separations. ### Claim 10 (depends on 6) The device of claim 6, wherein said sorting and stacking means comprises at least one stacking means disposed downstream of said suction belt means. ### Claim 11 (depends on 10) The device of claim 10, wherein said stacking means has a vacuum wheel, vacuum belts, and/or a delivery wheel. ### Claim 12 (depends on 11) The device of claim 11, wherein said delivery wheel is a vacuum drum or a delivery star. ### Claim 13 (depends on 11) The device of claim 11, wherein at least two delivery wheels are disposed next to each other on an axis, each delivery wheel having a different diameter. ### Claim 14 (depends on 11) The device of claim 11, wherein individual nest layers are pushed on top of each other to form a sorted stack by displacing said delivery nest against a lateral stop. ### Claim 15 (depends on 10) The device of claim 10, wherein, in dependence on a control of said suction cups, different blank rows are received and supplied in rows to one of said stacking means where the blanks are disposed and mixed a defined manner. ### Claim 16 (depends on 15) The device of claim 15, further comprising means for directly controlling each individual suction cup to permit distribution and mixing of individual blanks, received in rows, onto several stacking means. ### Claim 17 (depends on 15) The device of claim 15, wherein a plurality of stacking means are consecutively disposed. ### Claim 18 (depends on 1) The device of claim 1, wherein waste is directly separated from the blanks immediately downstream of said cutting means for removal over a surface of a cutting cylinder. ### Claim 19 (depends on 1) The device of claim 1, wherein a waste grid is guided over a surface of a counter pressure cylinder, downwards into a suction funnel, thereby separating waste from the blanks. ### Claim 20 (depends on 1) The device of claim 1, wherein said waste means comprise a chopper disposed downstream of said cutting means. ### Claim 21 (depends on 1) The device of claim 1, wherein the product web is printed in a predetermined transverse and longitudinal order. ### Claim 22 (depends on 1) The device of claim 1, wherein a pushing device pushes a sorted stack onto a transport belt. ### Claim 23 (depends on 1) The device of claim 1, wherein faulty blanks are transferred to a suctioning means at a suction cup wheel. ### Claim 24 (depends on 1) The device of claim 1, further comprising a print mark control, wherein said rotary cutting means cut out the blanks in exact register with the product web. ### Claim 25 (depends on 1) The device of claim 1, wherein the device is individually used as an offline machine or as an inline machine directly connected to other machines.
