Filter rod making machine

A filter rod making machine, comprising:

• a tow treatment section for forming a flat filter web from fibrous tow, said tow treatment section having an outlet through which the formed filter web is fed;
• a forming section for forming the filter web into a rod-shaped material, said forming section including a trumpet guide through which the filter web fed from the tow treatment section is passed so that the filter web is gathered up into the rod-shaped material;
• a wrapping section for receiving the rod shaped material from said forming section and wrapping the rod-shaped material in a paper web to form a filter rod continuum, said wrapping section having an inlet for receiving the rod-shaped material from said forming section;
• and
• a scatter section arranged between said tow treatment section and the trumpet guide of said forming section for scattering a granular additive evenly over the filter web, wherein
• said scatter section includes
• a reference level line connecting the outlet of said tow treatment section and an inlet of said wrapping section,
• a scattering position located near the outlet of said tow treatment section for scattering the additive, and
• a flat plate-shaped web guide arranged on the reference level line or above the reference level line and extending from downstream of the scattering position up to the trumpet guide, and
• said web guide bears the overall lower surface of the filter web and guides the filter web while the filter web is transported.
