Abstract
The spacing between the neighboring ends of successive pairs of coaxial plain cigarettes of unit length is changed during sidewise transport by two endless belt conveyors which diverge or converge relative to the direction of advancement of the pairs of cigarettes, namely at right angles to the common longitudinal axes of the pairs of cigarettes. If the spacing is to be increased, for example to provide room for filter plugs of double unit length in a filter tipping machine, the extent of axial movement of the cigarettes of each pair can be limited by lateral conveyors which flank, and are driven at the same speed as and at right angles to the axes of, the pairs of cigarettes approaching the station where the cigarettes are removed from the conveyors.
