Abstract
In a system for monitoring and controlling the thickness of a laminate, an apparatus is provided to apply material for forming a material layer onto a web so that a laminate is formed. The tip of a knife and the surface of the web upon which the material is applied define a space, and the knife is movable relative to the web to vary the size of the space. The web coated with the material layer is drawn past the knife to form a desired thickness material layer. A measuring apparatus measures whether the thickness of the material layer plus the thickness of the web is equal to a predetermined value. The tip of the knife is moved relative to the web to adjust the thickness of the material layer in response to a signal from the measuring apparatus. A method of monitoring and controlling the thickness of a laminate is also described.
