  • Chain link for conveying chain of a machine of the tobacco-processing industry
    Patent number: 7377097
    Abstract: A chain link for a conveying chain of a machine of the tobacco-processing industry, in particular a storage device for a rod-shaped tobacco product, includes holding means for a hinge pin and a hinge pin bearing for connecting the chain link to adjacent chain links, and a carrying surface for carrying a tobacco product, which carrying surface is arranged substantially parallel to the hinge plane defined by the hinge axes. The chain link is designed laterally for cooperation with a deflection plate of the machine which rotates about a substantially vertical axis. During cooperation with the deflection plate the chain link is designed to pivot about a longitudinal pivot axis parallel to the longitudinal axis. The chain link has a guide element which cooperates with the deflection plate and which is designed in such a way that a pivot movement of the chain link about the longitudinal pivot axis is counteracted by a frictional force exerted by the deflection plate on the guide element.
