ABSTRACT:
Method and apparatus for the manufacture of cigarette filters containing particulate material. Filter material composed of cellulose acetate tow is fed in the axial direction through a gap defined between a first pair of rolls so that the transverse cross-section of the filter material is changed to a substantially oval shape. The filter material is then fed through another gap defined between a second pair of rolls so that the transverse cross-section of the filter material is further changed to a substantially heart shape and at the same time providing pockets at axially spaced positions. Particulate material is deposited in said pockets. The filter material is closed so that the deposited particulate material is positioned in the interior of the filter material and wrapped with wrapping sheets.
