Abstract: In the gravure coating apparatus, while a bead portion of a coating liquid is formed between a roll surface of a gravure roll to which the coating liquid is excessively supplied and a web that runs continuously, the web is pressed on the gravure roll by using a backup roll, whereby a desired amount of the coating liquid is applied to the web, a liquid supply device having an inclined surface that is inclined downward toward the roll surface and a gap too narrow for the coating liquid to flow down between the roll surface and the inclined surface is provided at a position near the bead portion on the upstream side in the direction of rotation of the gravure roll so that the coating liquid flows down on the inclined surface and is supplied to the gravure roll. A liquid return of an excess coating liquid that is not used for coating in the bead portion is less liable to occur, so that a streak trouble on a coating surface formed on the web can be prevented from occurring.

Abstract: A paster for the application of a film of water-containing adhesive to a running substrate of cigarette paper or the like automatically replaces the evaporated percentage of water when the substrate-processing machine is idle but the paster continues to circulate adhesive in order to prevent a rise in the viscosity of the then circulating and water releasing adhesive. The quantity of water in the circulating adhesive and other parameters (such as the temperature) of the adhesive are monitored by several sensors, and signals which are transmitted by such sensors are processed to regulate the admission of water in order to maintain the percentage of water, and hence the consistency, of the circulating adhesive within a range not appreciably departing from that when the paster is in actual use to apply one or more films of adhesive to the running substrate.
