Abstract
A method and apparatus for applying a viscous fluid to a moving substrate is disclosed. The invention includes providing a die assembly from a pair of plates which are separated by shim means to define a fluid passage. The fluid passage communicates with a fluid reservoir having an opening bounded by smooth surfaces for contacting the substrate. The supply of ink is metered to the passage. The substrate is moved in contact with the smooth surfaces and the fluid is applied thereto by the reservoir. The trailing or downstream edge of the smooth surface is formed with an acute angle. Other features are also disclosed.
