Abstract: A method and a device transport a flat object, especially a mail item, over a conveyor path. The transport device has two conveyor elements, a thickness sensor and a gap-altering device. With the aid of the thickness sensor the thickness of the object is measured, before the object reaches the conveyor path. With the aid of the gap-altering device the gap between the two conveyor elements is set to a computed value. The effect of this setting is that after the setting the gap is smaller than the measured thickness and the difference between the measured thickness and the gap is smaller than a predetermined limit. This setting is concluded before the subject matter reaches the conveyor path. The two conveyor elements clamp the object for a time between themselves and transport the clamped object over the conveyor path.
