  • Patent number: 5220819
    Abstract: A mechanism for feeding strip material into the nip between a pair of strip mill rollers includes opposed guides for engaging and capturing the edges of the material being fed into the nip. Each guide has a side wall, a top plate and a bottom plate that together define a tapered channel. The wide end or throat of the channel initially receives the material, while the small end of the channel guides the material into the adjacent nip. The guides are movable toward and away from each other to accommodate strip materials of different widths. Each guide journals a series of vertically extending rollers of decreasing lengths upon which the associated side edge of the strip material sequentially rides as it moves toward the nip. The lengths of the rollers substantially exceed the expected thicknesses of the strip material so that the lower ends of the rollers wear at a faster rate then their upper ends.
