Technologies and techniques for the dry manufacture of an electrode. A substrate is provided, and a primer material is dispensed on the substrate to provide a primer layer on the substrate, dispensing an electrode material on the primer layer and attaching the electrode material via pressure and/or temperature to provide an electrode material layer.

A coating device, comprising a supply roller having a first contact surface, and a counter-roller placed opposite the supply roller and a second contact surface substantially parallel to the first contact surface. The contact surfaces are at least a substrate width in width and maintain a mutual gap for receiving the substrate therein in contact with both contact surfaces. The supply roller and counter-roller are each rotatable about their central axis. A liquid is supplied to the supply roller. At least the contact surface of the supply roller or the counter-roller is axially adjustable along the central axis thereof. Adjusting means align an edge of the contact surface of the supply roller and the counter-roller with a side of the substrate. An opposite edge of the other of the supply roller and the counter-roller is aligned with an opposite side of the substrate.

A device for lacquer transfer is disclosed having a frame, a nozzle with a dispensing end for dispensing lacquer, and a transfer roller with a circumferential lateral wall, a circumferential outer contact surface of the lateral wall comprises several depressions, wherein the nozzle and the transfer roller are arranged such that lacquer is dispensable from the dispensing end onto the outer contact surface and into the depressions, wherein the transfer roller is configured to roll with the outer contact surface on a work surface of a workpiece for transferring the lacquer from the outer contact surface and from the depressions to the work surface of the workpiece. A first hardening unit is formed as a UV-light unit configured for partially hardening the lacquer in a contactless way by emitting UV-light, the first hardening unit is arranged within an interior space defined by the transfer roller. The lateral wall of the transfer roller is transparent for UV-light, and the first hardening unit is arranged such that UV-light is emittable towards the work surface in a first operational area of the work surface to partially harden the lacquer in the first operational area.

Roller coater (1) for applying paint to mainly flat panels (8), comprising, in the direction of conveying of panels: a feed roller (9), preferably coupled to a contrast roller (39); an application head for applying paint, comprising an applying roller (3) and a dosing roller (11), said applying roller being preferably coupled to a contrast roller (33); a conveyor (12) for the panels (8) to be painted, preferably in the form of a closed belt conveyor;

characterized in that said applying head (9) is covered by its own cover (5), said application head is covered by a preferably vertical cover (2) and a preferably horizontal cover (6), which covers are removable, said applying roller being rotatably mounted on rotation supports (15) placed at its two ends, which are disengageable from said applying roller, said applying roller being withdrawable from its working position and distanceable from said working position in the application head through a withdrawing path providing an initial translation for disengaging it from its rotation supports in the direction of the feed roller (9) and a successive translation in a lifting direction, i.e. distancing it from said conveyor (12), there being provided a lifting member of said roller, preferably coupleable to the ends of said applying roller, the interaxis distance between said feed roller (9) and said applying roller (3) is at least equal to the length of the initial translation path for disengaging the applying roller from the rotational supports (15), and lower to the minimal length of the panels paintable with said roller coater (1).

A coating device for supplying a liquid to a substrate, particularly in the form of an optionally printed web, foil, strip or sheet, comprises a reservoir for holding a quantity of liquid. Coating means are provided which are able and configured to take liquid from the reservoir and transfer it to the substrate. Supply means deliver the liquid into the reservoir during operation. The supply means are controllable and are able to lead a constant liquid flow into the reservoir. The reservoir is provided with level detecting means which are able and configured to detect a liquid level in the reservoir. Provided between the level detecting means and the coating means is a control which controls the coating means during operation on the basis of a detection (LS) of the liquid level in the reservoir in order to maintain the liquid level at a fixed value.

A tandem system of metering and donor rolls is used to apply two different adhesives to a fully adhesive backed multilayer sheet to produce variably distributed adhesives and properties. Each of the two adhesives is unique and is cured differently to create a layer of adhesive that has differing adhesive properties on the sheet. A clear adhesive is applied to a top portion of cards before they are cut from the sheet and has a higher tackiness than the adhesive applied to the rest of the cards on the sheet in order to reduce glue buildup on blades cutting the cards from the sheet.

A method for producing a multilayer film including at least two layers joined by a two-component adhesive includes the following steps: spreading a first component A of a two-component adhesive on a first face of a first layer of film; spreading a second component B of the two-component adhesive on a first face of a second layer of film; bringing the first and second faces of the first and second layers into mutual contact joining the components and to form an adhesive and join the two layers in a multilayer film; and winding the multilayer film obtained.

At the time of forming a paste layer on a substrate sheet by use of three rolls placed at right angles, in order to offset a variation amount of a first gap due to thermal expansion of the rolls, a variation amount in a given detection period is calculated by use of outputs of a first sensor configured to detect a coating film surface of a second-roll coating film of a second roll and a second sensor configured to detect a second-roll surface, and the first roll is moved by use of a first-roll moving mechanism.
