A drying device includes a roller, and the drying device is for drying a recording medium conveyed by rotation of the roller. The drying device includes a first heating source and second heating source included inside the roller; first and second temperature detectors for respectively detecting a temperature of a first region on a surface of the roller and a temperature of a second region on the surface of the roller; and a heating controller that controls heating and termination of the heating by the first heating source and/or the second heating source, wherein, upon detecting that a temperature of one region of the first region and the second region is higher than or equal to a predetermined temperature, the heating controller terminates heating by one heating source corresponding to the other region.

A treatment device (1) and a treatment method for a web (2) of endless material, in particular of a textile fiber material, preferably a non-woven fabric are provided. The treatment device (1) includes a treatment chamber (14) in which the moving web (2) is treated with a flowing gas, in particular air, an inlet (10) and an outlet (11) for the web (2), and a plurality of chamber regions (20-24). The plurality of chamber regions (20-24) are stationarily arranged on top and next to each other. The web (2) runs through the plurality of chamber regions (20-24). In the chamber regions (20-24), the gas, in particular the air, flows against and through the web (2) from one side.

A printing apparatus, such as a large-scale ink jet printer, includes a drying module having a set of lamps disposed near a sheet path. A set of louvers can be positioned so that a portion of each louver can be interposed between the lamps and a sheet path. In one embodiment, the lamps are held by a set of lamp mounts, and each louver is pivotable around one lamp mount. In one embodiment, the louvers cover the lamps in response to a detected condition within the printer, such as a sheet jam or high temperature.

The present application provides an oven drying apparatus and a coating device. The oven drying apparatus comprises an oven drying chamber and a heating assembly. The oven drying chamber is equipped with a first oven drying side having a plurality of first air inlet portions for fluid medium to enter the oven drying chamber. The heating assembly is disposed on the first oven drying side. The first oven drying side is further provided with at least one air return portion provided between two adjacent first air inlet portions, and the air return portion being configured for fluid medium in the oven drying chamber to be discharged from the oven drying chamber. The arrangement of an air return portion between two first air inlet portions can discharge fluid medium between the two first air inlet portions and take away the heat, thus avoiding accumulation of heat between the two first air inlet portions.

Systems and methods for concentric arrangement of web conditioning modules in a dryer of a printing system. In one embodiment a dryer includes a drum, first rollers positioned in an arc around the drum to define a web path between an entrance of the dryer and the drum, and second rollers positioned along the arc between the first rollers and the drum that reverse the web path between the drum and an exit of the dryer. The dryer further includes first web conditioners positioned along the arc and beyond the first rollers from the drum that direct energy toward a portion of the web path that is between the entrance of the dryer and the drum. The dryer further includes second web conditioners positioned along the arc between the second rollers and the drum that direct energy toward a portion of the web path that wraps around the drum.

The invention relates to a process for manufacturing a laminated material (S) comprising a fibrillated cellulose layer, characterized in that it comprises the following steps: (a) depositing a suspension (1) of fibrillated cellulose on a filtration membrane (2) and draining the suspension through that membrane so as to form a wet layer of fibrillated cellulose (A) having a dryness, that is to say a ratio between the mass of dry matter and the total mass of the fibrillated cellulose layer, of between 5% and 18%; (b) transferring the wet layer (A) under pressure to an at least partially hydrophilic surface of a substrate (B), so as to form the laminated material (S); (c) drying the laminated material. The invention also relates to a device for implementing the process.

A method of manufacturing a composite film, the method including: a coating step including coating a coating liquid containing a resin on one surface or both surfaces of a porous substrate to form a coating layer; a solidification step including solidifying the resin by bringing the coating layer into contact with a solidifying liquid to obtain a composite film including the porous substrate and a porous layer that is formed on one surface or both surfaces of the porous substrate and that includes the resin; a water washing step including washing the composite film with water; and a drying step including drying by removing water from the composite film while transporting the composite film at a transport speed of 30 m/min or more using a drying apparatus including a drying device including a contact type heating device and a hot air blowing device, wherein the composite film is brought into contact with a contact type heating device as well as exposed to hot air blown from a hot air blowing device, to remove water from the composite film being performed by bringing.
