  • Compressed sheet and method of manufacturing thereof
    Patent number: 5292579
    Abstract: A compressed sheet comprises: base fibers constituted by inorganic fibers other than asbestos, or organic fibers, or a combination of both; a rubber; rubber chemicals; and fillers. In the compressed sheet a material with both smoothing and reinforcing effects is exposed at least to one of the surfaces of the compressed sheet. A method of manufacturing a compressed sheet comprises the steps of processing a composition for forming the compressed sheet by feeding it into a pair of rolls comprising a hot roll and a cold roll, thereby laminating the composition into a sheet-shaped material on the hot roll, and then peeling off the sheet-shaped laminated material. In this method the composition is fed into the rolls such that a material with both smoothing and reinforcing effects is exposed at least to that surface of the sheet-shaped laminated material which faces the cold roll.
