An electrode plate manufacturing method of the present disclosure uses an electrode plate manufacturing apparatus including: a first roll and a second roll facing each other at a first position; and a third roll facing the second roll at a second position, and the manufacturing method rotates the first to the third rolls, feeds an electrode material at the first position, and brings a current collecting foil to pass through the second position. The electrode plate manufacturing apparatus includes: a flow passage roll having a flow passage thereinside and an outer circumferential surface disposed to be in contact with an outer circumferential surface of at least one of the first roll, the second roll, and the third roll; and a circulating unit circulating a fluid through the flow passage. The circulating unit circulates the fluid through the flow passage of the flow passage roll during manufacturing the electrode plate.

A system may include: a coating form roller; a metering roller adjacent to the coating form roller; and a sealing chamber. The sealing chamber may include first and second blades that engage with the coating form roller and the metering roller, respectively.

A gravure coater test apparatus includes a gravure roll and a backup roll which are circumscribed to each other, a motor which drives the gravure roll partially submerged in a water-based pressure-sensitive adhesive for coating, a controller which adjusts the rotational speed of the motor, a doctor blade which is selected from a plurality of types to scrape the water-based pressure-sensitive adhesive from the surface of the gravure roll being rotated, and an infrared analyzer which allows at least one of the type of the water-based pressure-sensitive adhesive corresponding to the selected doctor blade, the uniformity of the coating surface, and the amount of the coated water-based pressure-sensitive adhesive to be confirmed.

A roller coater for applying paint to mainly flat panels having different lengths includes a feed roller, an application head having applying roller and a dosing roller, and a panel conveyor. The feed roller has a cover, and the application head has vertical and a horizontal covers. Rotation supports enable a coupling and decoupling of the ends of the applying roller, and translation organs provide for withdrawing the applying roller along a L-shaped path, so as to cause an initial horizontal translation with a radial distancing, and a vertical translation. The translation organs include a vertical guide and a lifting organ for the applying roller, and removable coupling terminals at the ends of the applying roller. The interaxial distance between the feed and the applying rollers is at least equal to the length of the initial translation from the rotational supports, and shorter than the minimum length of the panels.

A device (4) for applying a viscous liquid, in particular an MFC dispersion, onto a moving substrate (52) comprises an inlet (72, 73a-73f) for the viscous liquid, a casting chamber (61a, 61b), a lower portion of which being open to the substrate (52), and a metering portion (69, 661), for limiting a thickness of a wet film that is formed on the substrate downstream of the device. The device further comprises a shear section (42) arranged inside the casting chamber (61a, 61b). The shear section (42) comprises a fluidization rod (68), arranged in the casting chamber (61a, 61b), for providing shearing of the viscous liquid inside the casting chamber (61a, 61b).

The present disclosure relates to a coating bar and a method for manufacturing a separator using the same.

The coating bar according to the present disclosure may form a coating layer having an area with different thicknesses by one coating.

Additionally, the method for manufacturing a separator according to the present disclosure includes forming a porous coating layer using a predetermined coating bar, to manufacture a separator including the porous coating layer having an area with different thicknesses. In particular, the present disclosure manufactures the separator having a larger thickness at the two ends than at the center, thereby avoiding a lack of adhesive strength at the two ends in a transverse direction in the adhesion between the separator and the electrode, and exhibiting uniform adhesive strength over the whole interface between the separator and the electrode.

The invention relates to a method which has applications in the furniture and component industry. In particular, planar workpieces are coated in order to adapt their exteriors to the wishes of individual customers. A curable substance is applied and a three-dimensional structure is thus produced, at least partially in the region of the narrow side surface layer.

A coating device for manufacturing an electrode on a substrate. A feed unit feeds a substrate into a pressing gap. A first metering unit accommodates a first powder and a second powder and parallel fills a first metering gap with the first powder and the second powder. A roller device has a first application roller, a first pressing roller unit, and a second pressing roller unit. The first metering gap is provided between the first application roller and the first pressing roller unit, and the pressing gap is provided between the first pressing roller unit and the second pressing roller unit. The first metering gap is provided for applying the first powder and the second powder, as a first at least two-ply layer to the first pressing roller unit via a first application force.

A method is proposed for manufacturing dry electrodes on a current collector with the aid of a roller system. The roller system includes at least three rollers and the current collector. A first roller and a second roller are rotated in opposite rotational directions. Powder is poured into a calender gap formed by the first rotating roller and the second rotating roller, the powder being carried on the second roller. A signal is triggered with the aid of a control unit for setting a laminating gap between the second roller and the third roller, the third roller and/or the first roller and the second roller moving toward each other in the direction of the current collector. At least the third roller is rotated in the opposite direction of the second roller. The current collector is moved through the laminating gap.

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.
