Abstract: A paste application apparatus capable of evenly applying a paste to each of the front portion and the rear portion of a coating target with a simple operation. The paste application apparatus includes a setting device for setting the velocity difference between the movement velocity of the target and that of a paste layer during application of the paste in order to evenly apply the paste to the front portion and the rear portion. The paste layer having a constant layer thickness on a substrate surface moves along an arc-shaped path, when viewed from the side, the target for coating moves along the tangential direction of the arc-shaped path at a constant velocity while being immersed to a predetermined depth relative to the paste layer, and thereby the paste is applied to the target for coating.

Abstract: In the gravure coating apparatus, while a bead portion of a coating liquid is formed between a roll surface of a gravure roll to which the coating liquid is excessively supplied and a web that runs continuously, the web is pressed on the gravure roll by using a backup roll, whereby a desired amount of the coating liquid is applied to the web, a liquid supply device having an inclined surface that is inclined downward toward the roll surface and a gap too narrow for the coating liquid to flow down between the roll surface and the inclined surface is provided at a position near the bead portion on the upstream side in the direction of rotation of the gravure roll so that the coating liquid flows down on the inclined surface and is supplied to the gravure roll. A liquid return of an excess coating liquid that is not used for coating in the bead portion is less liable to occur, so that a streak trouble on a coating surface formed on the web can be prevented from occurring.

The external electrode forming apparatus comprises a component conveyer belt, a belt feeding mechanism, a component-inserting machine, a component-reversing machine, a paste-coating machine, and a component-discharging machine. For the component-inserting machine, the component-reversing machine, and the component-discharging machine, pressure pins are used to insert or move the component chips.

Abstract: A coating applicator is provided having a plate cylinder including a cylindrical body about which a coating plate is mounted in sleeve-like fashion. The plate is the type used in the flexographic printing industry, and is made of photosensitive, monomeric material. The longitudinal edges of the plate are mounted to the cylindrical body using a clamping mechanism which permits easy installation and removal. Even with relatively light pressure, the photopolymer plate releases a substantial portion of the coating material when the plate is applied to a workpiece. Consequently, the composition and secondary rollers may be spaced apart by a gap slightly smaller than the thickness of the workpiece. Because of this gap, coating material does not tend to be applied from the plate cylinder to the secondary roller, thus reducing the safety and environmental problems associated with cleaning the secondary roller.

A supply roll has a surface for applying liquid coating to the resilient transfer surface. The supply roll surface and the resilient transfer surface are in pressure contact, and adjacent surfaces of the supply roll and the coating cylinder rotate in the same direction.

Abstract: A system and method for depositing a pattern of media on a moving surface includes a media depositing apparatus that deposits media in a predefined pattern on the moving surface. A media applicator roll having a media receiving region, such as engraved or raised portions, receives the media from a media feeder as the media applicator roll rotates.

The method for depositing a pattern of media includes synchronizing the speed of rotation of the media applicator roll with the speed of the moving sheet of material so that the media are precisely deposited as they are released from the media receiving region. The method also includes minimizing the distance that the media must drop from the applicator roll receiving region to the moving surface.

Abstract: The process and apparatus of the present invention teaches how to treat a well-integrated woven or non-woven web of hydrophobic fibers to make selective areas hydrophyllic. It also can be used to make a web of hydrophyllic fibers selectively hydrophobic. It uses a plurality of selectively adjustable covers on an applicator roll rotating in a bath of liquid to place the liquid material on selective areas of the moving web. In a preferred embodiment the web is non-woven and the fibers are hydrophobic in nature, e.g., dry-laid or melt-blown polypropylene or polyethylene fibers or spun-bonded hydrophobic filaments. A woven web made of cotton or other hydrophyllic fibers may also be used if the end result is to create partially hydrophobic areas on a hydrophyllic web. The areas of liquid are positioned on the web only where desired so as to eliminate the excessive cost of unwanted and unnecessary coating material. If the web is hydrophobic, the liquid makes that area hydrophyllic.
