Abstract
The laminator for laminating protective, appearance changing film layer onto surfaces of CD's, DVD's, and other discs has a heated laminating roller that will press a web carrying the film onto the disc in regions on which pressure can be applied. In order to maintain the roller at a uniform surface temperature, the roller is continuously rotated whenever the roll heater is energized and the roll temperature is above a selected level so that the roller will maintain uniform temperature between laminating operations. The laminator has a supply roll for the web carrying the film, and a circuit board carrying a memory device is mounted on the interior of a hollow core of the supply roll in a manner that permits making contact with stationary members on the laminator to read information for enabling operating. A hub ring on the laminator is movable to a position to be spaced from a disc so no lamination takes place above the hub ring.
