Abstract (en)
[origin: EP4256981A1] Provided is a manufacturing method for a filter segment that suppresses the displacement of a breakable capsule even when an external force is applied thereto. The manufacturing method for a filter segment according to the present invention is a method of manufacturing a filter segment for a tobacco product, including the steps of: applying a plasticizer to one or more breakable capsules held on the rim of an insertion wheel and to the rim of the insertion wheel; and burying the rim of the insertion wheel in a fiber bundle that extends in a direction tangential to the insertion wheel and allowing to release the breakable capsules, thereby embedding the breakable capsules in the fiber bundle.
