A drying device having a travel path along which a web (W) of paper travels, a plurality of drying ovens arranged side by side along the travel path, a plurality of conveyor rolls provided in each of the drying ovens to convey the web (W) along the travel path, a plurality of roll units each constituted by one or more of the conveyor rolls and separated from each other along the travel path, and a plurality of conveyor motors connected to the respective roll units to rotate the conveyor rolls, wherein a downstream one of the roll units with respect to the travel path is rotated at a lower rotating speed than an upstream one of the roll units.

Drying device and cigarette wrapping paper manufacturing machine using the drying device

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

Low ignition propensity cigarette and wrapping paper therefor

There is provided a machine of manufacturing a low fire-spreading web, having a travel path () through which a paper web (W) travels; an applicator () that is interposed in the travel path () and used to apply a combustion inhibitor () onto the web (W); and a dryer () that dries the web (W) applied with the combustion inhibitor (), further including a detector () that measures a parameter indicative of width of the web (W) that has passed through the dryer (); and a controller () that controls a drying condition of the dryer () on the basis of a measurement result obtained by the detector () so that the width of the web (W) falls within an allowable range.

Machine and method of manufacturing low ignition propensity paper by maintaining shrinkage rate of dried web within allowable range

An inspection system for coated paper includes a traveling web of paper, a coating device for forming bands on the web by applying a coating liquid in the width direction of the web such that the bands are spaced from each other in the longitudinal direction of the web at regular intervals, a drying device for drying the web having the bands, a detection unit which is arranged downstream of the coating device for detecting at least either defect in the bands or defect in the web that is caused due to application of the coating liquid. A control device is inputted with the detection result from the detection unit and includes a determination section for determining the type of defect from the detection result. A quality control unit is inputted with the determination result from the determination section and configured to manage the determination result.
