Abstract

A coating apparatus is disclosed for applying coating material onto a moving surface. The apparatus includes a housing (16A) which defines a chamber (18A) for the reception therein of the coating material (12A). The housing (16A) also defines an exit slot (20A) for the passage therethrough of the coating material (12A) from the chamber (18A). A shear applying device (28 A-G) is disposed within the chamber for applying shear to the coating material prior to application of the coating material onto the surface (14A). The shear reduces the viscosity of the coating material and maintains a reduced viscosity of the coating material prior to application of the coating material onto the surface so that uniform flow of the coating through the exit slot taken in a cross-machine direction is facilitated.
