Publication number: 20090039075Abstract: A heating element that can maintain a laminator at a predetermined working temperature is disclosed. A low-power heating filaments and a high-power heating filaments are sandwiched between insulators. The high-power heating filaments are shut down once it is heated to a predetermined temperature. The low-power heating filaments are then turned on to maintain a constant temperature. When the temperature drops below a predetermined temperature, the low-power heating filaments are shut down and the high-power heating filaments are turned on to heat up the laminator. The temperature is thus maintained within a predetermined range through such cycles.Type: ApplicationFiled: August 7, 2007Publication date: February 12, 2009Applicant: Michilin Prosperity Co., LtdInventor: T.C.
