what is the central circle of orb web spiders web called

I have never heard any special term for the central part of the web other than "orb." One source calls this section the "capture thread." "Second, the web has a stretchy, wet, sticky spiral thread that winds out in increasing spirals from close to the centre. This wet spiral thread is the capture thread."
