Claim 9:
10. Apparatus for separating blanks (P), comprising:
a conveyor (1) for continuously conveying a sheet metal strip (2) in a transport direction (T) to a laser cutting station (3),
a laser cutting station (3) having at least one cutting laser for concurrently cutting the sheet metal strip (2) so that a cut sheet metal strip (2) is 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),
a first conveyor belt (4) for transporting the cut sheet metal strip (2) downstream of the laser cutting station (3) in the transport direction (T),
a suction conveyor (5) operated by means of negative pressure for taking over the cut sheet metal strip (2) from the first conveyor belt (4) and for transporting the cut sheet metal strip (2) overhead in the transport direction (T),
a device (11, 11a) for 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),
a second conveyor belt (6) arranged in partial overlap with the suction conveyor (5) for receiving the at least one blank (P) discharged from the suction conveyor (5) by a second interruption of the negative pressure and for transporting the successively discharged blanks (P) horizontally in the transport direction (T) to a collecting station (7).
