摘要

A method and a device for supplying filter material to a filter rod forming machine, according to which a flat band of filter material, obtained working a single “tow”, is longitudinally cut in at least two strips, each of which is fed to a respective pneumatic device adapted to transform the respective strip in a respective cord. The cords are then fed to an inlet of the forming machine at positions evenly distributed about a central axial portion for forming a peripheral axial portion.
