    摘要: 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.
