The method and apparatus for delivering generally flat articles one by one make use of first and second conveyors. The first conveyor has a top article-supporting surface operated at a first linear speed in a forward direction. In operation, a stack of generally flat articles lies on one side on this top article-supporting surface longitudinally of the first conveyor. The second conveyor is installed in series with the first conveyor, operates at a second linear speed higher than the first linear speed in the forward direction, slopes upwardly in the forward direction, and includes a plurality of generally parallel, rotative longitudinal screws having respective threads structured to engage a lower edge of the generally flat articles. According to the method, the generally flat articles are jogged and thereby separated from each other through slipping of the lower edges of these articles on the successive ridges and grooves of the threads of the rotative longitudinal screws. In operation, a rate of processing of the generally flat articles supplied from a discharge end of the second conveyor to a downstream article-processing equipment is measured, and the first and second linear speeds are adjusted in relation to this measured rate of processing. Preferably, article-detecting proximity sensors are mounted at the discharge end of the second conveyor, and the first and second linear speeds are adjusted also in relation to signals from these article-detecting proximity sensors.
