How are carbon arrows made?

I was wondering if anyone has seen a source on how carbon arrows are made. I wonder this because I have seen rocket motor chambers made out of carbon and that process is pretty slow but results in a very strong product.

I noticed some new arrows on the market (Satellite) that claim all other arrows are like a sheet of carbon rolled around a mandel and therefore were not even and had a seam. I did contact Carbon Express and they claimed their arrows are made on a mandrel with a continuous wound carbon fiber and not wrapped. One of these manufacturers are lying. Then I look at Blackhawk and they appear to be carbon fiber on a mandrel then a wrap of a bonding layer on the outside.

Anyway, I find no photos/illustrations of how carbon arrows are manufactured. I suspect a lot of them come from the same plant in Korea also.
