  • Apparatus for producing sheeting having a fibrous surface
    Patent number: 4065245
    Abstract: A process is provided for manufacturing a product which has a fibrous surface and is formed by the conversion of a non-fibrous polymer, which process comprises placing a polymer between drawing surfaces which adjoin the polymer and adhere thereto and separating the surfaces. At least one of the surfaces is formed by a carrier for the polymer and for the fibers, through which carrier a fluid is blown such as to flow around the fibers in statu nascendi and orient and stabilize them as their viscosity increases. An apparatus for carrying out said process is also provided.
    Type: Grant
