Device for processing filter tow material, and device for the production of filters

A device for processing filter tow material for the production of filters for rod-shaped smoking articles, said device comprising:

• filter tow delivery means for supplying at least two filter tow strips;
• at least two tow guideways, wherein each of the at least two filter tow strips is separately guided in a respective one of the at least two tow guideways;
• and
• processing apparatuses for processing the filter tow strips, wherein each tow guideway is assigned a separately controlled processing apparatus comprising means for drawing a respective one of the at least two filter tow strips, wherein each means for drawing comprises a roller pair, and wherein the roller pair in one of the at least two tow guideways is arranged coaxial and side-by-side in a single unit with the roller pair in the other of the at least two tow guideways to define inner and outer roller pairs, wherein a first roller of the outer roller pair is positioned on a first shaft and a first roller of the inner roller pair is positioned on a first tubular shaft through which the first shaft extends.
