A manufacturing machine for manufacturing a wrapping paper web for cigarettes with a low ignition propensity has a coating device () at a coating position defined in a travel path () of web (W). The coating device () has a rotary screen () and a gravure roller () located on the opposite sides of the travel path () and functioning as back rollers for each other. The rotary screen () intermittently applies a liquid burning inhibitor onto one side of the web (W) to form a number of band layers (B) arranged at predetermined intervals in a travelling direction of the web (W), and the gravure roller () applies water onto the other side of the web (W) to form wet bands (A) arranged alternately with the band layers (B) in the traveling direction of the web (W).

Coated web manufacturing machine

A production method for producing a wrapper for cigarettes is provided wherein, with a web kept traveling, a combustion inhibitor in liquid form is intermittently applied to one surface of the web to form undried banded layers arranged with a predetermined space therebetween in the traveling direction of the web, water is applied to the surface of the web over its entire area before or after the combustion inhibitor is applied, and then the web is rapidly dried.

Production method of producing wrapper for cigarettes

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.
