  • Fabric for use in protection for chain saws
    Patent number: 4279956
    Abstract: The invention provides a pad for protecting against injuries caused by moving chain saw blades. A plurality of superposed woven composite fabrics formed of a tough synthetic resin are firmly held together at the periphery of the pad. Each composite fabric comprises at least two superposed fabric layers which are interwoven into a single layer along spaced substantially parallel strips. The interwoven strips allow the number of fabric layers to be reduced without reducing the effectiveness of the protective pad.
