Method and apparatus for the manufacture of a wrapping material strip free continuous filter rod in the tobacco-processing industry.

摘要

The invention relates to a method for the manufacture of a wrapping material strip free continuous filter rod (33) of the tobacco-processing industry, wherein the filter material (10) on a format belt (23) is applied and in a forming apparatus (20) to the continuous filter rod (33) is formed, wherein the continuous filter rod (33) in the forming apparatus (20) or in the direction of conveying (50) of the filter material (10) downstream of the garniture device (20) is supplied with energy, a composite of the filter material (10) to achieve.The present invention also relates to a device for the manufacture of a wrapping material strip free continuous filter rod (33) of the tobacco-processing industry, comprising a forming apparatus (20), in which a format belt (23) is movable, the filter material (10) of finite length can be wound.The method according to the invention is characterized in that the filter material (10) upstream of the step of depositing on the forming belt (23) is substantially fully separated.The device according to the invention is characterized in that a aufschauervorrichtung (12, 13, 14, 26) upstream of the forming apparatus (20) is provided, by means of which essentially completely separated fibers (10) to form a fibrous web (15, 15 '', 15 ") can be poured.
