In an electrode production apparatus disclosed herein an electrode material supplied between a circumferential surface of a first roll and a circumferential surface of a second roll is transferred to a surface of a separately supplied electrode collector, to thereby form an electrode mix layer on the electrode collector. A predetermined textured shape is formed on the circumferential surfaces of the first roll and of the second roll, the textured shape being formed through repetition of a predetermined relief pattern, at a given pitch, in a running direction. The pitch (smallest repeating unit) and a recess depth of the relief pattern are designed so that the following expression y≤0.2x−20 holds, where x (μm) denotes the pitch and y (μm) denotes the recess depth.

An adhesive application apparatus is provided. The apparatus uses a rolled on adhesive applied to a substrate. After roll application, an adhesive activator is sprayed onto the substrate. By spraying an activator onto the substrate after the adhesive is applied, the adhesive may be made tacky for adhesion, but the adhesive used for rolling may be highly stable and slow to dry/cure without said activator, which enhances rolled application effectiveness.

A method and a device for the application of starch on a moving fiber web, especially on a packaging paper web such as a testliner or a corrugated medium web, include first applying starch to a first roll and/or a second roll and passing the fiber web through a treatment nip formed by the first roll and the second roll. At least one of the first or the second roll, preferably both rolls, have a hardness of 15 P&J (Pusey & Jones) or lower, preferably 5 P&J or lower and most preferably 1 P&J or lower. The starch is applied to the first roll and/or the second roll by a slot die and/or a slide die and then transferred to the fiber web in the treatment nip.

Provided is a coating apparatus including: a liquid coating section; an adjusting section which is configured to be capable of coming into contact with and/or separating from the liquid coating section, and which adjusts an amount of the liquid in the liquid coating section; and a hardware processor differentiating the contact timing between the coated medium and the liquid coating section and the contact timing between the liquid coating section and the adjusting section in a case where the coated medium is coated with the liquid.

Continuous method including mixing water and cementitous powder to form slurry; mixing the slurry and reinforcement fibers in a single pass horizontal continuous mixer to form fiber-slurry mixture, the mixer including an elongated mixing chamber having a reinforcement fiber inlet port, and upstream of the fiber inlet port is an inlet port to introduce water and cementitous powder together as one stream or at least two inlet ports to introduce water and dry cementitous powder separately as separate streams into the chamber, a rotating horizontal shaft/s within the chamber, part of the chamber for mixing the fibers and slurry and moving the fiber-slurry mixture to a mixture outlet; discharging the fiber-slurry mixture from the mixer outlet; forming and setting the fiber-slurry mixture on a moving surface; cutting the set mixture into fiber reinforced concrete panels and removing the panels from the moving surface.

A device for a lacquer transfer is disclosed having a transfer roller, the transfer roller includes a cylindrical support body, a first ring element, a second ring element, and a tire, wherein the tire comprises a middle section forming a circumferential outer contact surface with several depressions. The transfer roller is configured to roll with the outer contact surface on a work surface of a workpiece for transferring lacquer from the outer contact surface and from the depressions to the work surface of the workpiece. The tire includes two annular end sections, which are attached to the support body resulting in two axially separated and circumferentially extending connections. The tire, the connections, and the outer shell of the support body are fluid-tight and arranged such that a fluid-tight main cavity is formed between the tire and the support body. The first and second ring elements are arranged in the main cavity and seated on the support body at a predefined distance in an axial direction (A) of the transfer roller from one another.

A method in which a stream of dry cementitious powder passes through a first conduit and aqueous medium stream passes through a second conduit to feed a slurry mixer to make cementitious slurry. The cementitious slurry passes through a third conduit and a reinforcement fiber stream passes through a fourth conduit to feed a fiber-slurry mixer which mixes the slurry and discrete fibers to make a stream of fiber-slurry mixture. An apparatus for performing the method is also disclosed.

An apparatus for the implementation of a process for the continuous manufacturing of steel strips for packaging coated with a passivation layer is provided. An apparatus contains a transfer roller; a coating roller contacting the transfer roller, a surface of the coating roller having a plurality of hexagonally shaped cells with a line count being from 50 to 200 lines per centimeter and a volume being from 5.Math.10.sup.−6 to 10.Math.10.sup.−6 m.sup.3 per square meter of the coating roller surface; and a tank containing an aqueous passivation solution, the tank providing the aqueous passivation solution to the coating roller.

A fluid for application onto a substrate is provided in a cavity of a hollow cylindrical application roller that has porous roller wall. Before reaching the transfer point to the substrate, fluid is regionally selectively pushed back away from the outer shell surface of the application roller, into the porous roller wall, by a knockback pressure, in order to regionally selectively produce the effect that, at the transfer point, fluid is located at the outer shell surface of the application roller or no fluid is located at the outer shell surface of the application roller. A regionally selective application of fluid onto a substrate may thus be efficiently produced.

A solid-state battery includes a third active material layer, a first solid electrolyte layer, a first active material layer, a first current collector layer, a second active material layer, a second solid electrolyte layer and a fourth active material layer in the order mentioned, wherein both the first and second active layers are anode or cathode active material layers. When both the first and second active layers are anode layers, both the third and fourth active layers are cathode layers. When both the first and second active layers are cathode layers, both the third and fourth active layers are anode layers, at least the first current collector layer extends to an outer side than the third and fourth active layers, and an insulating resin layer continuously across a surface of the extending part on one side, a side face and a surface of the extending part on the other side.
