  • Method of and apparatus for converting a single layer of rod-shaped articles into a mass flow
    Patent number: 5472078
    Abstract: A single layer of spaced-apart rod-shaped articles of the tobacco processing industry is advanced sideways toward a transfer zone wherein successive groups of two or more neighboring articles are diverted along separate paths against a concave friction surface of an intercepting member. The friction surface directs at least some of the diverted articles into a chamber where the articles are gathered to form a supply of superimposed articles. A belt or chain conveyor is employed to draw a continuous homogeneous mass flow of articles from the chamber.
