Abstract: An apparatus is disclosed for forming annular grooves or slits in rod-shaped articles such as cigarette filter plugs. The apparatus comprises a first endless belt or similar device and, spaced therefrom, a second element defining with the belt a channel of predetermined width. Preferably, the channel size can be adjusted by moving the belt, the second element or both toward or away from each other. The belt is driven to enable it, in cooperation with the second element, to transport a rod-shaped article along the channel. A forming device, preferably a rotating disk knife, has a portion disposed in the channel and cuts any article moved therealong. The second element is preferably contoured to be spaced a constant distance from the profile of the forming device, to insure that the groove formed in the article is concentric with the longitudinal axis of the article.
