Claim 0:
1. A method for separating blanks with the following steps: continuous conveying of a sheet metal strip (2) in a transport direction (T) to a laser cutting station (3),
concurrently cutting the sheet metal strip (2) by means of at least one cutting laser, a cut sheet metal strip (2) being formed from successive sections (AT) of the same cutting geometry, each of the sections (AT) comprising at least one blank (P) and at least one residual blank (RP) adjacent to the blank (P),
transporting the cut sheet metal strip (2) on a first conveyor belt (4) in the transport direction (T),
transfer of the cut sheet metal strip (2) from the first conveyor belt (4) by means of a suction conveyor (5) operated by negative pressure,
suspended transport of the cut sheet metal strip (2) by means of the suction conveyor (5) in the transport direction (T),
separately ejecting the at least one residual blank (RP) of each section (AT) by first interrupting the negative pressure in predetermined areas of the suction conveyor (5),
transporting the at least one blank (P) of each section (AT) into overlap with a second conveyor belt (6) and ejecting the at least one blank (P) from the suction conveyor (5) by a second interruption of the negative pressure, and
transporting the blanks (P) discharged one after the other by the suction conveyor (5) in the transport direction (T) to a collecting station (7).
