摘要： Apparatus and method for depositing controlled short intervals of electrostatic charge on a moving web substrate to be coated, including a mathematical model that estimates the charging performance of the apparatus. The model is constructed via benchtop characterization of the apparatus. The model is implemented in coating production via an algorithm comprising a best-fit equation representing the model predictions over a range of relevant input parameter values such as web speed, web capacitance, and desired web voltage. The apparatus includes an electrical charging apparatus, a power supply for powering the charging apparatus, and a controller programmed with the algorithm for automatically setting and controlling the intensity and duration of the output of the power supply to yield the optimal electrostatic potential on the charging apparatus. In operation, run-specific variables including web type and coating speed are also provided as inputs to the controller. The invention is useful in minimizing coating disturbances at starts and between-roll splices.

摘要： A method for electrostatically assisting in coating a liquid composition from a hopper to a web supported by a backing roller, characterized by the steps of a) neutralizing all charges on both surfaces of the web by passing the web through an appropriate electrostatic environment ahead of the coating point, and b) providing a uniform electrostatic field around the backing roller, which field extends through the web to engender an electrostatic “pressure” for urging the liquid composition toward the coatable surface of the substrate at the coating point resulting in an increase in the maximum coating speed achievable without onset of air entrainment at the coating point, improved thickness uniformity of coating, and a reduction in residual charge on the web after coating.

摘要： Electrostatographic toning with charged toner particles which are transported along a conveyor having an array of repeating sets of electrodes upon which an electrostatic traveling wave pattern is established. The traveling wave pattern causes already charged toner particles to slide and roll along the conveyor to a selection site whereat individual toner particles are either directed toward the receiver or are returned to a developer reservoir. The width of each of the electrodes for the traveling wave grid is comparable to the size of the toner particles such that the particles are transported individually along the conveyor. At the selection site, unwanted particles are deflected from the path to a receiver. The receiver can be placed against a conveyor plate to avoid the divergence and bouncing problems.
