Abstract

Abstract A method for measuring and delivering the thickness of a coating of material onto a sheet of material on a sheet of advancing material to uniformly maintain a predetermined thickness, which method includes the operations of: depositing on a sheet of material advancing a coating of a composition convertible into a plastic foam; advancing the sheet material coated in this way through a measuring and delivery zone in which a stream of compressed gas is directed to flow back to maintain an accumulation of excess composition while maintaining at least one layer of compressed gas between the composition and any surface of the medium directing the compressed gas stream towards accumulation, the thickness of the coating being measured immediately in front of said accumulation to uniformly maintain a predetermined coating thickness by means of said gas stream.
