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. This results in the formation of two rows of groups of three coaxial rod-shaped articles each, namely, two plain cigarettes of unit length and a filter mouthpiece of double unit length between them. The filter mouthpieces are connected with the respective pairs of cigarettes of unit length by adhesive-coated uniting bands so that each filter mouthpiece and the respective pair of cigarettes of unit length jointly constitute a filter cigarettes of double unit length. Uniting bands are obtained from two discrete webs of adhesive-coated tipping paper. The leaders of the webs are attracted to the peripheral surface of a suction conveyor which cooperates with two sets of orbiting knives serving to repeatedly sever the leaders of the respective webs to form two series of discrete uniting bands. Successive uniting bands of the two series are applied to successive groups of the two rows before the uniting bands are convoluted around the respective groups.
