The present invention provides a machine for manufacturing low ignition propensity wrapping paper for cigarettes having combustion inhibition bands (B) intermittently formed on a web of paper by applying a combustion inhibition agent solution to the web by transfer. The machine includes a gravure roll () for forming combustion inhibition bands (B) on a web, the gravure roll () having recesses () in an outer circumferential surface for receiving the combustion inhibition agent solution, the recesses () each having a contour corresponding to the contour of the to-be-formed combustion inhibition band and having a large number of lands () distributed therein and constituting parts of the outer circumferential surface of the gravure roll, and the recesses each being designed such that the total area of the lands within the recess is smaller than the area of the recess excluding the lands.
