  • Erosion control blanket and method of manufacture
    Patent number: 5786281
    Abstract: An environmentally sound vegetation growth-enhancing erosion control blanket is formed from an elongated rectangular excelsior/wood wool mat. The mat is held together with adhesive and a surface pattern is embossed therein. When the finished blanket is placed atop the ground, the blanket serves to shield the earth area from wind and water erosion forces, without the presence of the plastic netting often used in the prior art. As the ground vegetation grows, it ultimately replaces the blanket which decomposes and furnishes the ground vegetation with a nutritive mulch.
    Type: Grant
    Filed: February 3, 1997
    Date of Patent: July 28, 1998
    Assignee: American Excelsior Company
    Inventors: Timothy Prunty, Wendell E. Johnson, deceased, John W. Johnson, legal representative
