Abstract
Supply hopper for delicate, rod-shaped products, in particular in cigarette packaging machines, which hopper (1) is provided in its lower part with a plurality of separate discharge channels (2), each of which is divided by means of intermediate walls (4) into several ducts (3) which are vertical and parallel to one another, in each of which ducts (3) there is formed at least one substantially vertical row of cigarettes (S) which are superimposed on one another, whereas above the upper end (104) of each intermediate wall (4) there is provided a roller (6) which is horizontal and parallel to the axis of the cigarettes (S) in the hopper (1), and is rotated, preferably with oscillatory motion. According to the invention, in order to prevent to a large extent the formation of bridges of cigarettes which block the ducts (3), the rollers (6) are disposed quincuncially relative to a horizontal plane, i.e. they are alternately offset parallel to one another upwards and downwards.
