Abstract
Within a cotton candy machine a delay-on-break delay timer is used to delay the de-energization of the spinner-head motor for a predetermined period of time after the heater elements are turned off. Thus, while the heater elements are cooling down, the motor and spinner head continue to rotate. Once the heater elements are cooled to the point where they cannot melt or burn the sugar, then the motor can be de-energized and the spinner head allowed to stop.
