I don't know what they are properly called--however I've seen them in the
textile industry, in several size ranges, used to hold yarn spiral wound
("universal wound") on cardboard, phenolic, or metal tubes for both winding
and paying off into other processes (from "creels").

You may want to look around at textile manufacturer's (and supplier's)
sites.
