Abstract: A device for combining groups of at least two different types of filter segments for producing multi-segment filters in the tobacco industry in a continuous process includes a plurality of independent functional units that are each designed as a module.

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 and apparatus for producing multi-segment filter elements in the tobacco-processing industry. The multi-segment filter elements each include a first filter segment and at least one second filter segment. A sleeve element is arranged in the first filter segment. The second filter segment is inserted into the sleeve element in the first filter segment and the sleeve element is pulled out.

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: The invention relates to a method for processing filter material for use in the manufacture of tobacco industry filters wherein a mass of finite fibers is feed to a separating device wherein finite fibers are separated into essentially individual separated fibers and then transported to a continuous rod machine.

Abstract: Device for wrapping groups of filter segments with a wrapping material. The device includes a rolling channel defined between adjacent stretches of at least one first roller conveyor and at least one second roller conveyor. The rolling channel is structured and arranged to wrap the groups of filter segments with the wrapping material by rolling each of the groups of filter segments. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: A method and machine produces a continuous filter rod. At least one type of finite, essentially completely separated fibers is transported with transport air to a conveyor. A fiber nonwoven is formed on one surface of the conveyor to result in the fibers at least partially contacting one another. The fiber nonwoven is deposited onto a wrapping material web. The fiber nonwoven is then wrapped a material web.
