Publication number: 20120090799Abstract: Web to be formed into wrapping paper is applied with combustion inhibitor and then dried. Water is applied onto the entire surface of the opposite side to the combustion-inhibitor applied side of the web. The web applied with water is dried while pinched between drying and pressing rollers and stretched in a width direction. In this way, unwrinkled high-quality cigarette wrapping paper having a low ignition propensity can be stably and inexpensively manufactured. As the pressing roller, a heat-resistant rubber roller provided in its surface with a soft portion in a helical way is utilized.Type: ApplicationFiled: December 23, 2011Publication date: April 19, 2012Applicant: JAPAN TOBACCO INC.Inventors: Shinzo KIDA, Takafumi IZUMIYA, Yuzuru SAKUMA
