A coating apparatus includes: a container configured to accumulate a coating liquid; a rotatable coating bar arranged at an opening part so that the coating bar has a clearance between the coating bar and a downstream side end of an upstream side cover and a clearance between the coating bar and an upstream side end of a downstream side cover and a rotation axis direction of the coating bar is directed in a longitudinal direction of the container; a plurality of rotatable supports intermittently arranged along the rotation axis direction of the coating bar; and an in-liquid cover extending in the longitudinal direction of the container.

The present invention relates to an ultrathin foil transferring and processing process for reducing curling and preventing folding of an ultrathin foil which may occur in the ultrathin foil transferring and processing process, and comprises: a step of coating or mounting an electrostatic-inducing material on both ends of a roll to form a charging part; a charging step of rubbing an ultrathin foil and the roll during the transferring and rolling of the ultrathin foil, to charge both ends of the ultrathin foil and the roll with positive or negative charges; and an electrostatic force applying step in which an electrostatic force is applied to both ends of the ultrathin foil simultaneously with or after the charging step and thus the curling of the ultrathin foil is reduced.

There is disclosed a selective wetting apparatus comprising a roller rotatable about a roller axis and comprising a wettable roller surface; an applicator unit having a lip which extends parallel to the roller axis and is radially spaced apart from the roller surface by a gap, wherein the applicator unit is to convey liquid agent towards the roller so that the liquid agent forms a liquid bridge over the gap to wet a wetted axial portion of the roller surface; and a flow guide to direct a gas flow into a regulated axial portion of the gap to locally prevent formation of a liquid bridge, and thereby prevent wetting of a corresponding axial portion of the roller surface.

An electrode manufacturing apparatus includes a shaping roll and an opposed roll that sandwich an electrode therebetween and rotate in opposite directions, and a temperature adjusting unit. The temperature adjusting unit reduces a temperature difference between a central portion and an end portion in an axial direction, of at least one roll of the shaping roll and the opposed roll.

Moving an article after a material, such as a hot-melt adhesive, has been applied to a surface of the article is accomplished with an article transfer apparatus. The apparatus is comprised of a belt having a plurality of apertures extending there through that are effective to communicate a vacuum pressure from an inner surface of the belt to a contacting surface of the belt. The vacuum pressure secures and adheres the article to the contacting surface of the belt as the belt conveys the article. The vacuum pressure is distributed along the inner surface of the belt by a vacuum chamber, which is between a compression roller and a second roller.

A spray coating machine and process accommodates coating pans of various sizes and simplifies cleaning after particulate material in the pan is coated. A selected pan is supported on a trolley carried by a wheeled cart. After the cart is positioned adjacent the coating machine, the trolley and pan are extended into the machine, and then the pan lifted for support by a rotatable drive shaft and castors. The trolley is then removed from the machine, and the door is closed so that the coating process can commence. When coating is complete, the door is opened, and the trolley extended into the machine under the pan and raised for removal of the castors. Then, the trolley and pan are withdrawn from the machine. The trolley does not need cleaning after spraying, since the trolley is outside the machine during spraying of the coating solution.
