Abstract
A mass-producing filter tipping machine wherein two coaxial plain cigarettes of unit length are simultaneously severed to yield pairs of coaxial plain cigarettes of unit length which are moved apart to provide spaces for filter mouthpieces of double unit length. The filter mouthpieces are connected with the respective pairs of cigarettes of unit length by adhesive-coated uniting bands, and the resulting filter cigarettes of double unit length are subdivided into pairs of filter cigarettes of unit length. These filter cigarettes are converted into a single row wherein the filter mouthpieces of all filter cigarettes face in the same direction.
