ABSTRACT:
The apparatus comprises an inclined chute to which the articles are delivered in portions and from which they slide down into a tray which oscillates in a horizontal direction together with the chute. The tray is open at its end remote from the chute and at the top, but closed on its remaining sides. The tray is pivotally supported in extensions of the chute side walls so that it can pivot between a horizontal loading position and a vertical discharge position. In front of the open end of the tray there is provided a vertical plate which is coupled to the chute and the tray in such a way that in the horizontal position of the tray it closes the open tray end while in response to the pivoting of the tray to vertical position it is moved some distance down into the mouth of a subjacent bag, substantially retaining its vertical orientation. During the emptying of the tray the plate functions as one of the walls defining a discharge opening through which the articles are transferred to the bag.
