  • Counter-rotating knife paper tail ripper
    Patent number: 5413017
    Abstract: A paper tail ripper having a pair of rotatably mounted knives, air motors which counter-rotate the knives and a deflector which deflects the paper tail toward the knives. The knives traverse closely spaced overlapping circles as they counter-rotate. The deflector sweeps the paper tail onto a transfer mechanism, which transfers the paper tail away from the ripper, so that the tail may be threaded through a calender stack, etc. The ripper is pivotally mounted on the transfer mechanism for movement between storage and operating positions.
