How are tubeless wheels without holes in the rim bed assembled?
Does anyone know the answer to this? How do the nipples get inside? How are they oriented into the spoke holes? How are they held firm and not pushed back up into the rim while they are being screwed onto the spoke threads. I'm not saying I can't imagine some ways, just that I would like to know how it is actually done. I imagine the entry point is the valve stem hole, but the rest is rather mysterious. Thanks.

My guess is they are guided in place by using a magnet. Could be entirely wrong though.

I've wondered the same thing. IIRC, my Campy Shamals are like that.

How It's Made did a clip at the Fulcrum (AKA Campagnolo) factory:

Okay, so the nipples aren't magnetic but are made magnetic temporarily with the added in plug. Nifty. But I didn't get why the nipple didn't get pushed up into the rim when the spoke was pushed into it. Did anybody understand that?

Does the magnet hold the nipple in place while the spoke is threaded into it? Also, here is fulcrum's diagram if folks aren't youtube fans

What I saw in the video and in pictures 5 and 6 of the diagram was that the magnet is taken off before the spoke is threaded in. In my experience I would just push the nipple up into the rim if I did it that way. I wondering why that doesn't happen. I have to press nipples down through the hole above (missing in this case) to get it to thread onto the spoke.

Typical marketing double-talk. There's nothing simple about nipple replacement for sure. There's also nothing simple about spoke replacement if you happen to lose that nipple in the rim.

My guess is that the nipples are long enough that they can grab the protruding portion with a tool and hold it while they thread the spoke in. Some needle nose pliers would do the trick for the home-builder though perhaps there is a clamping type of spoke wrench out there that solves the problem in a more refined manner.

Here are the instructions:

basically you manually thread the spoke into the nipple 1st
