<p>A paper tail ripper having a pair of rotatably mounted knives, air motors which counter-rotate the knives, and an air jet which deflects the paper tail toward the knives. The knives traverse closely spaced overlapping circles as they counter-rotate. The air jet blows 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. A funnel-shaped housing is positioned over the knives to guide the deflected paper tail into a narrow feed channel centred over the knives.</p> |
