摘要
The present invention relates to a method for assembling a highly efficient cigarette filter by making a new type of filter structure starting with a sheet of fiber material, this sheet being shaped as a cylindrical casing according to known geometric shaping arrangements. More particularly, according to this method there is employed a sheet of fiber material which is transversally corrugated and which acts as an absorbent with regard to the products of tobacco smoke, and, there is impressed on certain portions of this sheet a wafer relief configuration so as to obtain on this sheet two different materials, the sheet is then cut into ribbons of the same width which are gathered in the form of a pile, said pile being then geometrically shaped in a cylindrical casing of homogeneous structure.
