An applicator head for a curtain applicator for coating a continuous material web with liquid or pasty application medium. The applicator head has an outlet edge extending substantially over the width of the applicator head. The application medium passes out of the applicator head in a free-falling curtain. A rinsing device allows the outlet edge to be supplied with a flowing gaseous rinsing medium. There is also described a method for coating a continuous material web by way of such a curtain applicator. The application medium passes out of the applicator head in the form of a free-falling curtain and subsequently comes into contact with the material web. The region of at least one of the outlet edges can be supplied with a flowing gaseous rinsing medium.

A method of coating an active material for a secondary battery according to one embodiment of the present disclosure is a method of coating an active material on an electrode current collector of a secondary battery, the method comprising the steps of: disposing a guide member on each of the left and right sides based on a moving direction of the electrode current collector, and coating the active material onto the electrode current collector between the two guide members.

An asphalt shingle manufacturing machine that includes a curtain die for applying a liquid release layer on an asphalt coated substrate. The moisture of the liquid release layer evaporates leaving a dispersed solid particulate release layer. The curtain die includes a first body section and a second body section with a shim disposed between the body sections to define a distribution channel. The second body section may include chamber manifold defined therein to store a volume of liquid release agent. The distribution channel places the chamber manifold in fluid communication with a discharge outlet of the curtain die in order to disperse a volume of liquid release agent from a chamber manifold out of the discharge outlet. The shim may be configured to define a width of the distribution channel to determine the flow rate and discharge pattern of the liquid release agent.

An apparatus for coating an object or component includes at least one dispenser for dispensing a falling flow of material and an actuator for projecting the component through the falling flow of material. A landing may also be provided for receiving the coated projectile, the landing adapted for providing a second coating to the coated projectile. Related methods are also disclosed.

A curtain coating device includes a curtain coating member, a conveyance unit, a separation member, and a base material supporting member. The curtain coating member creates a curtain-like film of coating liquid and makes the curtain-like film flow down. The conveyance unit conveys a base material to which the curtain-like film is to be applied. The separation member includes a receiving portion inclined downward from inside to outside in a width direction of the curtain-like film, and separates an end portion of the curtain-like film having flowed down by receiving the end portion with the receiving portion above the base material. The base material supporting member is disposed inside in the width direction of the curtain-like film than the receiving portion of the separation member, and supports the base material on an upper side flat portion while the base material is being conveyed.

A liquid knife cleaning apparatus and a liquid knife are provided. The liquid knife cleaning apparatus includes: a frame configured to be arranged on the liquid knife and be capable of reciprocating in an extending direction of the knife edge; a cleaning blade configured to extend into the knife edge of the liquid knife and be capable of reciprocating inside the knife edge under the driving of the frame to clean the knife edge, the cleaning blade being arranged on the frame; and a movable mechanism configured to control the frame to reciprocate on the liquid knife in the extending direction of the knife edge, the frame being connected to the movable mechanism.

An aerated wax application assembly comprises a meltable wax applicator, one or more meltable wax delivery conduits having a first end coupled to the meltable wax inlet of the meltable wax applicator and a second end positioned proximate a meltable wax holding tank, and an air injection system positioned upstream from the meltable wax applicator and configured to inject air into the meltable wax and generate the aerated meltable wax upstream of the inlet of the meltable wax applicator. A method of applying an aerated meltable wax onto an object comprises injecting air into a meltable wax such that it forms an aerated meltable wax, delivering the aerated wax through one or more meltable wax delivery conduits to a meltable wax applicator, and contacting at least one exposed surface of the object with the aerated wax when dispensing the aerated meltable wax from an outlet of the meltable wax applicator.

A curtain application unit for applying a liquid or pasty application medium to at least one surface of a moving material web, in particular a fibrous web, includes an application head having at least one separation edge extending substantially over the width of the application head. The application medium exits the application head in the form of a free-falling curtain at the separation edge. At least one rinsing device is used to apply a flowing gaseous rinsing medium to the at least one separation edge, and at least one blocking device is suitable for keeping air movements of the ambient air away from the curtain. A method for coating a moving material web is also provided.

A method for coating a material web (2), in particular a fibrous web, by way of a coating device. The coating device (1) has an application unit (3) for applying a coating medium to the material web. The application unit is arranged in the interior of an enclosure (4), which has first opening for the entry of the material web and a second opening for the exiting of the material web. In the interior of the enclosure there is produced a positive pressure greater than the ambient pressure outside the enclosure during the coating so that air flows from the interior of the enclosure to the outside (5b) of the enclosure through the first opening and/or the second opening.
