Flat article feed apparatus for feeding flat articles to a bin carrousel having bins that circulate around a loop in a certain direction, said apparatus being characterized in that it comprises: • a flat conveyor in which the articles are moved in series and as laid flat, and a platform carrousel having tipper platforms each of which is suitable for tilting between a horizontal position and an inclined position and that circulate around a loop in such a manner as to be synchronized with the bins of the bin conveyor and in the same direction; • in that the flat conveyor has a sloping free end that is vertically above the platform carrousel for the purpose of loading the platforms with articles coming from the free end of the flat conveyor when the platforms are in the horizontal position; • in that each of the tipper platforms has a tilt axis that extends transversely to the loop around which the platforms circulate, the tilt axis of each platform being disposed at the front of the platform in the direction in which the platforms circulate so that, in the inclined position, each platform has a rear side in the circulation direction that is aligned with the inside wall of a bin of the bin carrousel; • and in that each of the bins of the bin carrousel has a long dimension corresponding to a long dimension of the flat articles that extends transversely to the loop around which the bins circulate so that, in a rectilinear portion along which the platforms circulate on the platform conveyor and which is superposed on a rectilinear portion along which the bins circulate on the bin conveyor, each article loaded on a platform is injected into a bin by gravity and merely by sliding on the platform that is inclined towards the inside of the bin. • a flat conveyor in which the articles are moved in series and as laid flat, and a platform carrousel having tipper platforms each of which is suitable for tilting between a horizontal position and an inclined position and that circulate around a loop in such a manner as to be synchronized with the bins of the bin conveyor and in the same direction; • in that the flat conveyor has a sloping free end that is vertically above the platform carrousel for the purpose of loading the platforms with articles coming from the free end of the flat conveyor when the platforms are in the horizontal position; • in that each of the tipper platforms has a tilt axis that extends transversely to the loop around which the platforms circulate, the tilt axis of each platform being disposed at the front of the platform in the direction in which the platforms circulate so that, in the inclined position, each platform has a rear side in the circulation direction that is aligned with the inside wall of a bin of the bin carrousel; • and in that each of the bins of the bin carrousel has a long dimension corresponding to a long dimension of the flat articles that extends transversely to the loop around which the bins circulate so that, in a rectilinear portion along which the platforms circulate on the platform conveyor and which is superposed on a rectilinear portion along which the bins circulate on the bin conveyor, each article loaded on a platform is injected into a bin by gravity and merely by sliding on the platform that is inclined towards the inside of the bin.
