FILTER-TIPPED CIGARETTES AND METHOD FOR MANUFACTURING THE SAME Russian patent published in 2008 - IPC A24D3/04 

FIELD: filter-tipped smoking articles, cigarettes and method for manufacturing the same.

SUBSTANCE: filter-tipped cigarette has tobacco core wrapped in wrapping paper, filter joined with tobacco core wrapped along the entire length thereof into mouthpiece or other wrapping paper for filter, said paper differing from standard wrap for filtering tampon, and connection strip for covering of tobacco core and filter joint to thereby connect filter and tobacco core. Natural permeability of mouthpiece or other wrapping paper for filter is 50-500 units of Korest. Method involves making batches of filters on one and the same machine; wrapping filters through the entire length thereof with mouthpiece paper or other wrapping paper differing from standard filter wrap having natural permeability of 50-500 units of Korest and ventilation extent predetermined for each batch; feeding batches of filters wrapped with ventilated wrap to respective machines for manufacturing of doubled cigarettes with doubled filter positioned between two wrapped tobacco cores; joining filter with two wrapped tobacco cores by means of narrow joining strips; cutting doubled filter for producing two filter-tipped cigarettes. Thus, various batches of cigarettes with filter ventilation extent may be manufactured on different machines. Another method involves manufacturing cigarettes having filter wrapped with mouthpiece or other wrapping paper with natural permeability of 50-500 units of Korest, said wrapping paper differing from standard filter wrap and comprising powder material applied thereto and tobacco core wrapped in wrapping paper; to do that, feeding filtering tampon to machine connected with filter manufacturing machine and designed for applying of powder material; feeding mouthpiece or other filter wrapping paper for applying of powder material thereto; wrapping filtering tampon with wrap; cutting wrapped filtering tampon into parts having length corresponding to that of cigarette; feeding said parts to filter-tipped cigarette manufacturing machine, wherein using narrow joining strip for joining filter and tobacco core to produce filter-tipped cigarettes.

EFFECT: reduced consumption of materials without altering manufacture processes, and avoiding utilization of two or more various wrapping materials.
