Abstract: In an embodiment, a process for producing a functional-substance thin film material for which a required heating temperature for finishing is 100-130° C. is characterized in that a PP film 2 is releasably laminated to a surface of a PET film 1 with a non-silicone adhesive layer 3 so that the strength of adhesion of the PP film 2 by the non-silicone adhesive layer 3 is regulated so as to prevent the PP film 2 from suffering thermal deformation when a functional substance superposed in a thin film form on the other surface of the PP film 2 is heated to 100-130° C. in order to finally convert the functional substance into a functional-substance thin film material 4.

Abstract: A coating material supply nozzle has a coating material reservoir where a coating material fed from the outside into a nozzle body, and an elongated nozzle port, from which the coating material passed through a nozzle passage is discharged. A coating material feed pipe for feeding the coating material is mounted in the coating material supply nozzle to extend in said coating material reservoir over the entire length. The coating material feed pipe is provided with at least one coating material feed bore for guiding the coating material within the coating material feed pipe into the coating material reservoir uniformly in a lengthwise direction of the coating material reservoir.

Abstract: An apparatus for supplying gravure coating material in which coating material is directly supplied to a contacting portion of a doctor blade and a gravure roll. The apparatus includes a gravure roll, a doctor blade, supporting means for supporting the doctor blade in such a manner that contacting state of the doctor blade relative to the gravure roll is adjustable, a coating material primary reservoir for temporarily reserving coating material, measuring means for measuring and controlling the quantity of coating material fed from said coating material primary reservoir, and a coating material secondary reservoir for supplying coating material through the measuring means to a contacting portion of the doctor blade and the gravure roll.

Abstract: A gravure coating device and method for applying a coating to a first side of a traveling continuous web. A pair of spaced rollers support the web on the second side while a gravure roller located between the rollers tangentially contacts the first side of the web. A doctor blade is utilized to remove excess coating from the gravure roller while a nozzle is utilized to apply the coating material to the gravure roller.

Abstract: A coating feeder system is disclosed herein. The coating feeder system comprises, in close vicinity to an outer peripheral surface of a gravure roll, a coating container or vessel defining a reservoir for storing a coating under a pressurized condition and a stirring mechanism for stirring the coating within the reservoir. The stirring mechanism may be a stirring and feeding roll mounted within said reservoir. The stirring and feeding roll includes forcedly stirring means formed on an outer peripheral surface thereof for forcedly stirring the coating.

Abstract: A coating device including a supply roller, a coating applicator, a driving roller and a takeup roller all cantilever mounted on a surface of a vertical panel inside a casing. A continuous base member to be coated on one side if sprially guided by guide rolls from the supply roller past the coating applicator, past the driving roller and onto the takeup roller. The base member is contacted by the rollers on the side opposite the coating.

Abstract: A gravure coating device for applying a coating to a first side of a traveling continueous web. A pair of spaced rollers support the web on the second side while a gravure roller located between the rollers tangentially contacts the first side of the web. A doctor blade is utilized to remove excess coating from the gravure roller while a nozzle is utilized to apply the coating material to the gravure roller. Specific structure for the nozzle is disclosed.
