ABSTRACT:
An improved laminator includes two heat conductors each having a roller channel receiving a silicone roller and a heating tunnel containing a mica heating plate. The roller channel and heating tunnel are separated by a thin wall so that the heat generated by the heating plate is easily conducted to the silicone roller, whereby when a picture and an upper and a lower layers of plastic films are pressed by the heated silicone rollers, the plastic films are molten and attached on the picture to form a lamination. The laminator has a base formed with a central fixing sink which has two opposite axial notches and two circumferential slots located under and beside and communicated with the notches. One end of each of the circumferential slots has an upper window, whereby a temperature controller with two terminals is locked in the fixing sink to measure and control the temperature of the heat conductors.
