Okay, here is my latest envisionment... An air filled bladder sits at the bottom of the tube. The bladder has a convex surface, so the center of the bladder is the first thing that will hit the lens. The tape could come in pre-cut circles (like the little circles used for edging AR coated lenses- only larger). You throw a circle on the bladder (sticky side up) and push the lens front down onto the bladder. The bladder (which could be adjusted since it is air filled) gives way and presses evenly from the center out (eliminating air bubbles on top of segs), and because the tape is already cut, there's no need for a knife of any sort.
