摘要
A projectile launching device includes self-timing without cam lean. The projectile launching device preferably includes a rail, a riser, two energy storing components, (such as two limbs), two cams, a launch string, and at least two cables. The ends of the launch string are attached to the two cams. Opposing ends of first and second cables are coupled to the first and second cams. A mid-segment of the first and second cables are slideably engaged with the first and second cable pulleys, respectively. The two cams are preferably built as mirror images of each other at a centerline of the rail. The two cams include a launch string track, having identical, but mirrored, upper and lower cable tracks.
