MACHINE AND METHOD OF MANUFACTURING A LOW FIRE-SPREADING WEB AND A METHOD OF MANUFACTURING A LOW FIRE-SPREADING WRAPPING PAPER USED FOR CIGARETTES

摘要

Disclosed is a machine for producing a low-ignition-propensity web, which is provided with: a travelling path (2) on which a paper web (W) travels; a coating device (3) which is position above the travelling path (2) and which coats a combustion inhibitor (7) on the web (W); and a drying device (4) which dries the web (W) that was coated with the combustion inhibitor (7). The aforementioned machine for producing a low-ignition-propensity web is also provided with: a detector (9) which measures the parameters that indicate the width of the web (W) that passed through the drying device (4); and a control device (10) which controls the drying conditions of the drying device (4) on the basis of the measurement results obtained by means of the detector (9) so that the web (W) width is within an allowable range.
