  • Roving package wrapper
    Patent number: 5147040
    Abstract: A roving package wrapper comprises a roving package formed by roving wound into a cylindrical configuration, and a collapse prevention member or material bonded to the outer surface of said package for maintaining or supporting the roving of the outermost layer thereto. Therefore, the collapse prevention material or member is adhered to the outer surface of the roving package, and has enough strength to adhesively hold the outermost roving when the outermost layer of roving only remains, thereby preventing the collapse of the roving.
