Chuck
p.s.
Is this the chuck you have on your wrapper?

If so, it is a fine chuck.
You indicate that you have the rod is coming loose.
Is your rod coming loose because the chuck is changing its adjustment, or is the rod coming loose, because it is slipping out of the jaws with the clamping pressure you put on the chuck?
If you do have the upgraded chuck, I am guessing that you don't have an issue with the chuck changing its adjustment - very difficult to have happen - but rather the rod is working its way out of the chuck jaws.
If the chuck adjustment is staying fixed - I am guessing that it is - I think you need to change the surface on your chuck jaws to keep the rod from slipping.
In addition to that, if you wrapping a rod with a tapered butt cap, it is going to be very difficult to hold it in place with any chuck.
Having said that, I have found that one solution to the issue, if you have the upgraded chuck is to remove the plastic or rubber covering over the jaws of the chuck.
Then, take cork strips the same width as the jaws and use transfer adhesive to adhere the cork to the face of the jaws. It seems that the cork faced jaws do a much better job at holding the handle in place compared to either the rubber or vinyl or plain metal jaws of the chuck.
In addition - a fail safe way to secure the rod in your power wrapper - assuming that your chuck jaws don't move - is to wrap the rod before you add the butt cap to the rod.
Secure the rod in the power wrapper by using a solid fiberglass, metal, or graphite rod - either ground to the right size or built up with masking tape to insure a good friction fit into the butt of the rod blank.
If you use a piece of solid rod that goes several inches into the butt of the rod, and then - starting from the tip of the inserted rod, build up the inserted rod with layers of masking tape so that the tip is a friction fit into the butt of the rod blank. Then, work back toward the butt, building up layers of tape so the next rod of tape build up is a friction fit into the butt of the rod. This will absolutely keep the rod in place on the inside of the blank.
Under normal circumstance, I have never found any issues at all with the plain metal chuck, the rubber or vinly coated chuck or cork coated chuck keeping the solid rod in place.
As a matter of fact, most of the time, on new rod builds, I use a different chuck on my power wrapper. It is a simple 1/2 inch keyless chuck in which I insert the solid rod and then insert the built up tape coated rod into the butt of the rod for wrapping.
I do this for convenience and simplicity, since the keyless chuck makes rod changes virtually instant. No need to get the johnny bars to tighten or loosen the chuck.
Summary-
If you do have the upgraded pac bay chuck on your wrapper, I doubt very much that the jaws are actually changing their adjustment during power wrapping. If the rod is coming loose, I am guessing that it is because the rod is working out of the chuck jaws with no adjustment change happenning in the chuck. To resolve the problem, remove any covering on the metal jaws, and add a layer of 1/8th or 1/16th cork with transfer adhesive to the metal jaws and I suspect that the problem will go away.
However, if you are trying to wrap a rod with a tapered butt cap, I would suggest that you remove the butt cap and power wrap with a solid rod built up with masking tape to secure the rod from the inside of the blank, and then chuck the solid rod into the chuck for wrapping.
Take care
