COATING WEIGHT MEASURING AND CONTROL APPARATUS AND METHOD |
| 摘要 |
A sensor for determining the basis weight of coating material on a substrate is described. The determined basis weight is insensitive to changes in the amount of substrate material underlying the coating. Signals from the sensor may be used in the control of a coating mechanism to provide a coating having a uniform basis weight.
