专利汇可以提供Filter production process专利检索,专利查询,专利分析的服务。并且PURPOSE: To produce a rod filter in a simple process without using rolled paper by a method wherein cellulose filaments treated with special material are treated with microwave while they are being formed or after being formed.
CONSTITUTION: Continuous two is pulled out from the cellulose filaments 1 as filaments 2, which are passed through the slitted air blower 3 and are opened to fibers, then is tensioned by the drum 4. The unit 5 is used to apply to the above filaments a material such as glycerine traicetate which can be given filament-to- filament adhesive force by microwave treatment. Then, the filament is sprayed with water by the unit 6. The opened tow 7 is passed through the guide 8 and guided, along with endless tape 14, into the tongue 9, then is exposed to microwave irradiation by the microwave generator 12 of the garniture 10. Then the endless tape 14 is released, and the tow is cut by the cutter 15 to the desired length.
