Abstract

Apparatus for stacking and storing a plurality of flat objects, such as letters. The apparatus includes at least one storage box and a loading device designed to transport the flat objects from a source and to project them into the interior of the box. The box and loading device are respectively positioned so that the flat objects are projected into the box at an incline with respect to its bottom and a portion of each object's leading edge impacts a stopping surface formed in one of the side walls of the box. This impact imparts a rotational couple to the object which brings the lower edge of the object into firm engagement with the box bottom. The object is then moved onto the stack of similar objects being formed in the box, either by gravity or an auxiliary device. In one preferred embodiment, relative movement is provided between the box and loading device so that the objects can be projected into the box at a point close to the top of the stack. Other embodiments provide for automatic feed of boxes past the loading device so that loading can be performed continuously.
