  • Patent number: 5570732
    Abstract: The log feeding device includes a feeding wheel that has an upper side portion axially from a lower side portion and a rim extending therebetween. The side portions extend outwardly and laterally from the wheel. An elastic tire is mounted on the rim of the wheel between the upper and lower side portions. A flexible net is attached to the upper and lower side portions and is conformable to the shape of the elastic tire. The flexible net includes a plurality of chain strings that are attached to the side portions at connection points. Each chain string has one end attached to an upper connection point and an opposite end attached to a lower connection point so that there is a diagonal straight distance between the upper and lower connection points. One set of the chain strings forms an angle A relative to one side of the longitudinal axis and the other set forms the same angle A relative an opposite side of the longitudinal axis of the wheel.
