A fountain for applying a coating color on a surface of a web which is engaged with a backing roll for movement of the web is supported by an application adjusting mechanism such that the fountain can be angularly adjusted around a tip of the fountain so that the, fountain angle can be adjusted without changing a gap between the tip of the fountain and the surface of the web. The application adjusting mechanism may be installed on a dwell time adjusting mechanism which is pivoted around an axis of the backing roll so that the dwell time can be adjusted without changing the gap between the tip of the fountain and the surface of the web as well as the fountain angle.

Why it's free to use
- Filed June 12, 1991 and granted March 28, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 12, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 12, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
