Abstract
In at least one embodiment, an archery bow includes a rotatable member comprising a cam track, a capstan and a terminal. A drawstring extends from the first rotatable member. A power cable is attached to the terminal and extends away from the rotatable member. The power cable comprises an elongate straight portion located near the rotatable member, a capstan portion in contact with said capstan and a terminal portion in contact with said terminal. In a brace condition, the power cable wraps around the capstan in a first rotational direction as the power cable is traversed from the elongate straight portion to the terminal portion. When the bow is drawn from the brace condition, the rotatable member rotates in a second rotational direction that is opposite the first rotational direction.
