Abstract
A link chain which transports and compacts tobacco leaves in a tobacco shredding apparatus has a succession of neighboring metallic links each of which has a trailing end provided with a cylindrical male coupling portion extending into and turnable in a complementary socket at the leading end of the next-following link. The socket is formed at the inner side and the coupling portion is at the outer side of the respective link. Each outer side has a convex cylindrical surface at its front end, and such surface slides along a complementary concave cylindrical surface at the rear end of the outer side of the preceding link. Each link is further formed with a scraping edge which cleans the convex cylindrical surface of the next-following link. The convex cylindrical surface of each link bounds a portion of a recess which is formed in the outer side and is adjacent to the coupling portion of the respective link. The outer side is fluted to enhance the transport of tobacco leaves into the range of a comminuting device, and the inner side has a pair of protuberances bounding the respective socket and a tooth space which is disposed between the socket and the coupling portion.
