ABSTRACT:
A compound archery bow includes a handle having at least one projecting limb, and a pulley mounted for rotation on the limb. Bow cable segments extend from the bow pulley, including a bowstring cable segment extending from a bowstring let-out groove on the pulley, a second cable segment extending from second cable let-out on the pulley, and a third cable segment extending from a cable take-up groove on the pulley. Draw of the bowstring cable segment away from the handle withdraws the bowstring cable segment from the let-out groove on the pulley and rotates the pulley around its axis, withdraws the first cable segment from the cable let-out on the pulley, and winds the second cable segment into the cable take-up groove on the pulley. The cable take-up groove is contoured such that the draw force on the bowstring cable segment increases as a function of draw to a first level, and then decreases to a second level less than the first level and at which draw force remains substantially constant.
