The lowermost flat object is downwardly detached from the rest of the stack of flat objects by negative pressure on at least one of its edge areas) running parallel to the take-off direction. In at least one suction area, the flat object is held by negative pressure onto a conveyor that can move back and forth. The flat object is advanced underneath a scraper and then further conveyed. The device for carrying out this process has a hopper for the stack of flat objects, a scraper, at least one suction device to partially detach the lowermost flat object, a conveyor, and a take-off device.
