摘要:
A low ignition propensity cigarette has wrapping paper (6) wrapping filling material into a rod-like shape, and the wrapping paper (6) includes highly conducting bands (10) formed by calendering and arranged in a longitudinal direction of the cigarette, the highly conducting bands (10) having higher thermal conductivity than inherent thermal conductivity of the wrapping paper (6), and burning depression bands (16) formed in the wrapping paper (6) and superposed upon the respective highly conducting bands (10).

An air permeability inspection device for a filter cigarette (FT) has plate-like packing (18a). The packing (18a) covers an opening of a movable tube (10) and an end surface of the filter cigarette (FT) is relatively pressed to the packing. The packing (18a) has a hole (18c) positioned at the center of the pressed end surface, an inner annular region (18f) surrounding the hole (18c), and an outer annular region (18g) surrounding the inner annular region (18f). The outer annular region (18g) is more likely to be elastically deformed than the inner annular region (18f) and comes to be in intimate contact with the outer peripheral edge of the pressed end surface.
摘要:
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.
