Abstract
The arrow rotation device of the present invention substantially reduces the described disadvantages of prior art arrow rotation systems by inducing a rotation on the arrow shaft prior to leaving the bow and entering free flight. It is an object of the present invention to provide a means for inducing a rotational velocity about the longitudinal axis of an arrow as it travels through the bow over the releasing range. It is another object of this invention to provide an arrow rotating system that can be used with existing archery bows with minimal modifications or available as a factory option (OE). It is a further object of the present invention to provide a means for mechanically inducing a rotational velocity about the longitudinal axis of an arrow through a constant or a variable rotational acceleration to achieve a desired rotational velocity prior to separation of an arrow from the bow.
