Abstract:
The invention is a contact die for dispensing of flowable material on a substrate. The contact die includes at least one die block including a first internal passage. A die lip portion is disposed on the die block having a lateral dimension. A first plurality of orifices is disposed through the die lip portion proximate to each other and in communication with the internal passage to dispense flowable material as a single strip on the substrate. A first edge is disposed on one lateral side of the first plurality of orifices to direct the flowable material.
Abstract:
An electrical connection means 45 guides a DC voltage, which is generated in an ion sheath when a plasma is excited, to a first electrode 31 where a substrate W is placed. Hence, the DC voltage is applied to both the upper and lower surfaces of the substrate W, so the two surfaces of the substrate have the same potential. As a result, element breakdown, which occurs when a large potential difference occurs between the two surfaces of the substrate W, can be prevented.
Abstract:
The present invention is a foam applicator system for applying foam to a tissue web. The foam applicator system comprises a foam applicator capable of applying a liquid-based composition to a tissue web. The foam applicator includes an extrusion head comprising a first nozzle bar and a second nozzle bar and having an inner surface and an outer surface. A first end of a flexible scraper is operatively associated with the first nozzle bar of the extrusion head. A second end of the flexible scraper outward from the first end of the flexible scraper. The foam applicator system may also comprise a vacuum slot positioned opposing the extrusion head with the tissue web therebetween.
Abstract:
A method and apparatus for anodizing a component. The component is placed in a container having first and second seal members that seal an annular surface of the component to be anodized. The first and second seal members, the annular surface of the component, and an inner surface of the container form a reaction chamber that holds a reaction medium therein. The reaction medium is supplied to the reaction chamber through a supply passage formed in the container. The reaction medium is drained from the reaction chamber through a drain passage formed in the container.
Abstract:
A method and apparatus is provided for applying a plaster-like coating material to the decorative exposed surface of a preform workpiece. The apparatus comprises; means for mechanically advancing a workpiece along the apparatus along a straight horizontal axis over a non-continuous surface; means for engaging the bottom portion of a workpiece to constrain lateral and vertical movement as the workpiece passes along the apparatus; and means for applying a desired thickness of plaster-like coating material to a decorative surface of an advancing workpiece. Both the method and apparatus provide on a consistent basis, a smooth coating with a controlled thickness tightly bonded to the entire exposed decorative surface of a workpiece. The method and apparatus provide a simple, efficient, cost effective and reliable means for applying a plaster-like coating to the exposed decorative surface of a workpiece for use on a commercial scale in the construction industry.
Abstract:
Coating apparatus including a coating vessel including a vertical wall having a vertical interior surface having a circular cross section and an imaginary vertical axis, an open top and a bottom, a vertical shaft supported on the bottom of the coating vessel, the shaft having an axis aligned coaxially with the imaginary vertical axis of the interior surface having the circular cross section, and a coating liquid inlet/outlet adjacent to the bottom of the coating vessel.
Abstract:
An apparatus for controlling coating weight on a steel strip in a continuous hot dip galvanizing process, in which the coating weight is controlled through air wiping after the steel strip passes through a molten zinc coating bath. More particularly, the apparatus keeps the steel strip equidistant from each air knife, uniformly distributes a spray pressure of the air knives in a widthwise direction of the steel strip, and minimizes variation in coating weights on both surfaces of the steel strip. Furthermore, when two steel strips that are different in thickness are continuously hot dip galvanized, the apparatus predicts the movement of the passing line of the steel strips and accurately controls the positions of the air knives. As a result, product deficiencies such as insufficient coating can be reduced and zinc loss due to excess coating can be minimized.
Abstract:
In order to provide a coating apparatus in which an edge can be fixed rigidly so as to apply a coating agent at a uniform thickness, edge units are provided which comprise edge support members and edges which are attached to the tips of the edge support members so as to slide on a flexible tape support member. The edge which is not disposed at both ends in the running direction of the flexible tape support member is fixed to the edge support member by an edge fixing member which is inserted in a direction from a bottom portion of the coating apparatus toward the edge. The edge is fixed so as to be pulled into a recessed section formed on the edge support member by the edge fixing member.
Abstract:
A non-impact process and apparatus for coating printing cylinders with layers of a coating liquid, especially for coating flexographic printing sleeves with infrared sensitive layers.
Abstract:
An apparatus and method for plating a workpiece. The apparatus comprises, generally, an anode, a cathode, and a selective anode shield/material flow assembly. In use, both the anode and the cathode are immersed in a solution, and the cathode is used to support the workpiece. During an electroplating process, the anode and the cathode generate an electric field emanating from the anode towards the cathode, to generate a corresponding current to deposit an electroplating material on the workpiece. The selective shield/material flow assembly is located between the anode and the cathode, and forms a multitude of adjustable openings. These opening have sizes that are adjustable during the electroplating process for selectively and controllably adjusting the amount of electric flux passing through the selective shield/material flow assembly and the distribution of the electroplating material on the workpiece. The selective shield/material flow assembly can also be used with an electroless plating system. At least one selective shield material flow mechanism is used in a selective shield material flow assembly.
