    Abstract: Paint or the like coating is applied to a gap between an elongated strip article and an extended surface, such as a coating head. A variable load, such as provided by air cylinders, is continuously exerted on the extended surface during operation for urging the extended surface against the applied layer on the strip, so as to maintain a uniform metering gap between the extended surface and the coated strip surface. The extended surface has a sensor for repetitively determining metering gap. A computer monitors the sensor output and causes load-exerting air cylinders to vary their applied load, in order to urge the coating head toward or away from the back-up roll, so as to reduce difference between the sensed metering gap and a predetermined gap, thus producing a uniform coating film thickness on strip articles having non-uniform surface topography.

    Abstract: A time-efficient method for smoothing a surface 20 of an applied coating composition 22 is disclosed herein. In particular, the present invention sets forth a technique for expediting the subsidence of coating surface nonmetallic vertical irregularities R1, R2. The technique of the present invention is applied subsequent to the application of the coating composition 22 to an electrically conductive object 24, which results in the formation of a coating surface 20. The technique of the present invention includes the step of generating electrically charged particles 40 in a volume of space adjacent to the coating surface 20. The charged particles 40 cause an electric field to develop across the coating composition 22, which induces the charged particles 40 to exert pressure on the coating surface 20.

    Abstract: Method and apparatus for coating a moving web and for independently controlling the coating's width, thickness and uniformity of thickness along the length of the web. A back-up roller supports the moving web on a portion of the roller's periphery. A stationary and pliant smoothing film is positioned adjacent the exposed surface of the web which is supported by the back-up roller. A coating liquid is metered to the confluence of the web and the smoothing film, the metering rate being selected to produce a desired coating width. A pliant pressure generating means, in the form of a membrane or a force web, holds a length of the smoothing film against the moving web with a static force whose magnitude is selected in accordance with a desired coating thickness. The relative position of the back-up roller and the pressure generating means determines the length of coincidence of the moving web, the coating liquid, and stationary smoothing film. This length is selected, by virtue of selecting a relative position, to apply high hydrodynamic pressure to the coating liquid for at least a critical time interval, such that slight variation of this time interval does not produce appreciable variation in coating thickness along the length of the web, and lineal uniformity of coating thickness is thus achieved.

    Abstract: A controller for maintaining a constant thickness of a layer applied to work pieces fed through a liquified curtain, the curtain itself being provided through a positive displacement pump which is driven by a motor having means for varying its speed from a remote locate. The work pieces are fed by an infeed conveyor, which is also driven by a motor of the variable speed type, and magnetic pickups or sensors are provided to produce two discrete trains of pulses indicative of the speed of the infeed conveyor, and of the positive displacement pump respectively. A digital readout ratio calculating unit is provided to produce a display indicative of the ratio of these pulse train frequencies, and the unit can be preset to provide an input to low and high limit preset counters. The preset low and the high preset counts are electrically connected to relays, which control the speed of the pump motor itself through conventional circuitry, and the resulting controller provides for continuously updating the speed of the pump motor to maintain a predetermined ratio of its speed to that of the infeed conveyor for maintaining a predetermined coating thickness on the work piece.

    Abstract: A cleaning method of cleaning a solution treatment apparatus for applying a coating solution onto a substrate, the solution treatment apparatus including a holder holding and rotating the substrate; a coating solution supplier; and an inner cup surrounding the holder from a lateral side and having a peripheral edge side upper surface inclining down outward in a radial direction. The cleaning method includes introducing the cleaning solution to the storage chamber via the introduction hole, discharging the cleaning solution from the discharge port and making the cleaning solution flow down along the peripheral edge side upper surface of the inner cup, thereby cleaning away the coating solution adhering to the peripheral edge side upper surface. The discharging in the cleaning discharges the cleaning solution from discharge ports of the inner cup outward in the radial direction and obliquely upward.
