Publication number: 20050113232Abstract: 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.Type: ApplicationFiled: November 15, 2004Publication date: May 26, 2005Applicant: Hauni Maschinenbau AGInventors: Stephan Wolff, Thorsten Scherbarth, Sonke Horn, Irene Maurer, Alexander Buhl, Jann De Boer

Publication number: 20040250823Abstract: 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.Type: ApplicationFiled: April 2, 2004Publication date: December 16, 2004Applicant: HAUNI Maschinenbau AGInventors: Peter-Franz Arnold, Sonke Horn, Uwe Heitmann, Thorsten Scherbarth, Alexander Buhl, Stephan Wolff
