A sealing agent (25) sent from a nozzle tube (36) to a nozzle main body (37) is passed through a main body flow channel portion (37a), a connecting portion (37c), a first flow channel portion (37b), and plural second flow channel portions (37d), sent to a chamber (37e), and discharged from a nozzle port (37f) to the outside. Since the second flow channel portions (37d) are smaller than a downstream end of the first flow channel portion (37b), the sealing agent (25) in the first flow channel portion (37b) is vigorously sent to the chamber (37e), and discharged from the nozzle port (37f) to the outside. As a result, substantially the same quantity of the sealing agent (25) is discharged in the entire range of the chamber (37e).

Disclosed is a slot die coater for coating an electrode active material slurry on an electrode current collector, which includes a lower die having a lower outlet, and an upper die disposed above the lower die and having an upper outlet, wherein an upper surface of the lower die and a lower surface of the upper die are at least partially in contact with each other and capable of sliding relative to one another such that the upper die and the lower die are capable of sliding relative to each other along a horizontal direction.

A spray applicator is disclosed. The spray applicator can include a carrier body including a number of contact surfaces and at least two nozzle bodies. Each nozzle body can be fastened on one of the contact surfaces and have a spray slit for producing a spray jet fanned out transversely to a center plane. the center planes can cross one another along a straight line. The straight line can extend outside the carrier body. The contact surfaces can face the straight line and be offset with respect to one another in the direction of the straight line.

An applicator die for creating undivided ribbons of polymeric film and a method of using the die to apply an emulsified polymeric material in ribbons to a fully or partially finished surface of an automobile body. In one application, the ribbon is applied as a peelable film to an automobile body and in another application, a ribbon is applied to a rocker panel as an anti-chip coating. For both applications, the applicator die has an internal gallery and an outlet slot with flared edge surfaces to emit a laminarized ribbon of polymer-based material at a distance from the target surface where the opposite edges of the ribbon have become essentially parallel.

An applicator die for creating and applying laminarized ribbons of polymeric film to a target surface, such as but not limited to a surface of an automobile body component. In one embodiment, the protective film is an aqueous emulsion of polyvinyl acetate and is used to create a continuous peelable film to protect a surface. In another embodiment, the polymeric is polyvinyl chloride and it is applied to create an anti-chip coating. The applicator die has an internal supply gallery and an outlet slot of complex shape to emit a laminarized ribbon of polymer-based material that allows the material to be applied directly to the target surface without masking. A robot is used to control movement of the die. The die includes temperature control.

A coating device is provided for application of a coating agent, in particular a paint, sealant, separating agent, function layer or adhesive, to a component such as a motor vehicle body and/or attachment therefor. The coating device comprises an applicator that has at least one outlet opening and is configured to emit at least one coating agent jet. The coating device includes a deflector that is configured for deflecting the coating agent jet.
