Abstract
A mechanism for advancing flat-laid package blanks disposed in a magazine includes a shaft extending through the mechanism at right angles to the magazine and journalled by way of a free-wheel hub so that it may rotate in only one direction. The shaft is urged against at least one endless elastic belt which passes around two or more wheels. The belt presses against the flat-laid package blanks. The free-wheel hub is surrounded by a lever that is connected to a drive unit. When the lever is pivoted in one direction by the drive unit, the movement is transferred via the shaft to the belt and the package blanks are fed forwardly in the magazine. When the lever is pivoted in the other direction, the free-wheel hub locks and no movement is transmitted to the belt which might otherwise counteract the forward advancement of the package blanks in the magazine.
