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: A device for processing filter tow material used for producing filters for rod-shaped smoking articles such as cigarettes. The device includes a filter tow supply to provide at least two filter tow strips to at least two filter tow guideways. Each of the at least two filter tow strips is directed within the at least two filter two guideways, respectively. Apparatuses are also provided for processing the filter tow strips. The device includes a separately controllable independent processing apparatus assigned to each filter tow guideway.

Abstract: A processing unit for processing at least one filter tow strip to produce filters for rod-shaped smoking articles includes at least one tow guidance section along which the filter tow strip is moved in a direction of a longitudinal extension of the filter tow strip. The tow guidance section includes processing devices used for processing the filter tow strip. The processing devices are arranged in a sequence essentially one above the other, so that at least a segment of the tow guidance section that is located in a region of the processing devices is oriented at an angle to a horizontal line.

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 rod-cutting device and method of the tobacco-processing industry. The device includes a rotatable cutting body with a cutting edge, and a first rotary body with a rotation axis on which the cutting body is arranged. The cutting body is arranged essentially parallel to the rotation axis of the first rotary body, and has an extension at least from a mounting point to the cutting edge. A tangent of the first rotary body extends through or parallel to the extension.

Abstract: A roller for a device for processing a filter material ribbon in the tobacco-processing industry. The roller comprises a roller core and a covering for the roller core. The roller has at least one wear indicator operatively arranged for indicating wear of the covering.

Abstract: Filter, method of forming filter, and filter cigarette. The filter includes at least a first filter component composed of polyethylene fibers and a second filter component composed of a granulate. 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 arrangement are provided for producing compound filters for products in the tobacco-processing industry. A filter tube, having a filter element in a central region of the filter tube, is supplied to a predetermined position. Predetermined portions of filtering material are then inserted into the filter tube from at least a first end of the filter tube so that filter segments form in at least a first part of the filter tube.

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.
