Abstract: Method and device for producing filter rods of the tobacco-processing industry. The method includes combining and mixing fibers of finite length of two different fiber types, and separating the combined and mixed fibers. The combining and mixing occurs directly before the separating.

Abstract: The invention relates to a method for producing a nonwoven fiber composite for the manufacture of filters in the tobacco industry, wherein the method feeds separated fiber materials to a fluidized bed and the separated filter material inside the fluidized bed are transported to a rod-forming device, essentially by a transport air flow flowing in the direction of the rod-forming device and the filter material is compiled on the rod-forming device prior to forming the compacted fiber filter elements.

Abstract: Method and device for producing a filter rod. The method includes melting at least one first type of filter material, pressing the at least one first type of filter material through at least one nozzle, depositing the at least one first type of filter material on a conveying element, and shaping the filter rod on the conveying element. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: A method of making a non-wrapped filter rod in the field of the tobacco processing industry, includes the steps of applying filter material to a forming belt where the filter material is substantially fully separated prior to being applied to the forming belt; shaping the filter material in a forming apparatus into the filter rod; and exposing the formed filter rod in the forming apparatus to energy to obtain a bond of the filter material. In addition, an apparatus for making a non-wrapped filter rod includes a fiber shower-producing apparatus where substantially fully separated fibers of a filter material may be accumulated to form a non-woven web; and a forming apparatus having a moveable forming belt for receiving the separated fibers of the filter material where the forming belt is capable of being wound about filter material of finite length to produce a filter rod.

Abstract: A method for producing a nonwoven for the manufacture of filter rods in the tobacco industry includes separating fibers of at least one type of filter material in at least one separating device having at least one separating element rotating about a rotational axis. The separated fibers are fed to a conveyor moving in a conveying direction such that the separated fibers form the nonwoven.
