    Abstract: A covering is produced by placing a green web including an air-containing fabric layer having a first thickness and a surface layer in a mold having a predetermined shape, and compressing the green web into the predetermined shape such that the air-containing fabric layer and the surface layer unite to each other while the air-containing fabric layer reduces to a second thickness smaller than the first thickness. The resulting compressed green web has a solidity that holds the predetermined shape.
