Abstract
An improved cotton candy machine melts sugar by inductively heating a spinning head and preferably a perforated spinner band on the spinner head. An induction heater is disposed in a machine base beneath the rotating spinner head and excites the band to a heat range for melting and spinning elongated molten strands of cotton candy from raw sugar. Electric heater strips, electric conduits, electric terminals, electric slip rings and electric spring-loaded brushes are all eliminated. Methods are disclosed.
