Abstract

A device for locking a suction nozzle of a separating sucker on a suction head of a sheet feeder of a sheet-processing machine, the suction head carrying a device for vertically moving the suction nozzle of the separating sucker, and a drive device for guiding at least one forwarding sucker reciprocatingly in accordance with a working cycle of the sheet-processing machine and substantially parallel to the plane of a sheet supplied to the feeder, including a bearing support laterally disposed on the suction nozzle, a movably arranged abutment device for supporting the bearing support, when the suction nozzle is in a lifted position, until a trailing edge of the sheet supplied to the feeder has left the vicinity of the suction nozzle of the separating sucker, and a member connecting the abutment device to the drive device for the forwarding sucker.
