Abstract
A method and apparatus for manufacturing tobacco filters are provided. Tobacco filter components are placed on a tape of wrapping paper which has a larger edge-to-edge size than the circumference of the filter components. Said tape is guided around the filter components at its first part which is adjacent one of the edges to half wrap the filter component. Paste is applied to the first part surface which faces radially outwardly and then, the tape is guided around the filter components at its second part which is adjacent the other one of the edges to lap over said paste-applied first part.
