Abstract
A fountain type web coating applicator and method wherein flow of coating material from source to a doctor blade coating nip with the continuously travelling web is subjected to a plurality of successive pressure drops so that coating material reaches the coating nip uniformly throughout the extent of the doctor blade edge. One of the pressure drops is through a multi-port pressure drop device and another pressure drop is through a slit orifice pressure drop device. A novel arrangement for easy replacement clamping of the doctor blade is provided. A doctor blade thruster is adjustable up and down along the blade relative to the upper coating nip edge of the blade.
