The present invention provides an adhesive layer coating unit configured to continuously apply an adhesive layer having a first width in a longitudinal direction of a first separator. The adhesive layer coating unit comprises: a transfer roller configured to support a bottom surface of the first separator and transfer the first separator; a discharge roller configured to transfer the first separator, which has passed through the transfer roller, in conjunction with the transfer roller while supporting a top surface of the first separator, wherein a coating groove having the first width and a closed curve shape is formed in a circumferential surface of the discharge roller; and a coating member configured to inject an adhesive into a space between the discharge roller and the top surface of the first separator which has passed through the transfer roller.

As the adhesive flows in the coating groove of the discharge roller, the adhesive layer having the first width is continuously applied on the top surface of the first separator.

A system for manufacturing a positive electrode for a secondary battery includes an unwinder wound with a positive electrode base material, a first coating unit for coating an insulating material at predetermined positions about widthwise edges of the base material with respect to a transfer direction of the base material supplied from the unwinder, a first drying furnace for drying the insulating material by heating the base material coated with the insulating material, a second coating unit for coating a positive electrode slurry on the base material supplied from the first drying furnace in a region between the insulating material formed at both sides of the base material, and a second drying furnace for heating and drying the base material coated with the insulating material and the positive electrode slurry.

Examples disclosed herein relate to application of a coating fluid. Examples include an apparatus including a first coating applicator to apply a coating fluid to a plurality of first rollers; a first transfer roller in contact with the plurality of first rollers to receive coating fluid; and a media path to apply coating fluid from the first transfer roller to a first side of a media, wherein the plurality of first rollers are shorter than the first transfer roller and are individually movable along its longitudinal axes such that they may positioned to apply a variable width of coating fluid onto the first transfer roller.

A coating system and method including a web path moving a substrate past a contacting element including a distribution manifold having a cavity, and a multiplicity of needle tubes in fluid communication with the cavity, the needle tubes each having a needle tip dispensing a coating material towards a point of contact between the substrate and the contacting element. In some embodiments, the distribution manifold separates into a manifold containing the internal cavity, and a removable cartridge having the plurality of needle tubes. The coating system and method can be used to apply a pre-metered coating material to the substrate.

A sealing blade includes opposite elongated edges (30, 31) and between them a flat (32) and which is adaptable to a blade holder (17) arranged in a coating applicator (25) of a coating device (21) and into contact with a moving surface (11′). The sealing blade has a contact surface (33), which may be arranged against the moving surface and which is 5-15% of the width (W) of the sealing blade (10).

A high-quality coating film with a uniform thickness is produced without crush of coating particles even in a case where a wet coating material that does not require a step of drying the coating material is used, while maintaining high productivity. By providing a surface layer with an optimized hardness on the surface of a roll used for supply of a mixture coating material, a high-quality coating film with a uniform thickness can be produced, even in a case where a wet coating material that does not require a step of drying the coating material is used, while maintaining high productivity.

Packaging for storing and displaying raw wet protein portions is described. In particular, the packaging has: a housing for containing one or more portions of raw wet protein; an antibacterial coating on a surface of the housing; and a tracer indicating presence of the coating. A system and method for coating the packaging is disclosed as well as a method of detecting antibacterial food packaging.

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 apparatus is used for coating a web of material or a sheet of material with a hot-melt adhesive (14). In order to simplify the application of hot-melt adhesive to webs of material or sheets of material, it is provided that the apparatus (10; 110) has a heated surface (25; 124) and a supply roller (16) with hot-melt adhesive (14) movable perpendicular to its axis of rotation, the web of material or the sheet of material being movable relative to the supply roller (16) while in contact with the heated surface, a pressure apparatus, which presses the supply roller (16) against the heated surface (25: 124), and a drive apparatus being provided, which drive apparatus causes the supply roller (16) to roll on the web of material or the sheet of material.
