Abstract

PURPOSE:To suppress total electric power of a plurality of heating means at the prescribed value or below by deciding a priority rank order for a plurality of heaters and firstly heating the arbitrarily combined heaters having low temp. CONSTITUTION:When a main switch SW is turned ON, the surface temp. of a pressurizing and heating roller set 10 is detected. This detected temp. is compared with the preset temp. When this detected temp. is lower than it, laminating heaters 13a, 13b are turned ON. In the case of reaching the prescribed temp., the heaters 13a, 13b are turned OFF. Then the surface temp. of preheating rollers 9a, 9b is detected. The detected temp. is compared with the preset temp. When the detected temp. does not reach the preset temp., the preheaters 12a, 12b are turned ON. When the surface temp. reaches the prescribed temp., this preheaters are turned OFF. Then when a laminating object 20 is absent in a feeding route 22, temp. regulation is again performed. When the same is present, only the temp. control of pull rolls set 15 is performed. Thereafter the rear end of the object 20 is trapped and it is judged whether lamination is completed. When the object 20 is present, the temp. control of the roller set 10 is performed. When the object 20 is absent, the temp. control of the roller set 10 and the rollers 9a, 9b is performed.

Detailed Description of the Invention (a) Industrial Application Field The present invention is a method for laminating an object by sandwiching the object between upper and lower heat-reactive laminate films and applying pressure and heat to the object. The present invention relates to a laminating device that performs lamination processing while sealing with a film.

(0) Prior Art Conventionally, a laminating apparatus has been known that improves the appearance and shelf life of a sheet-shaped laminated object by wrapping the front and back sides of the laminated object with a laminating film and sealing the laminated object.

FIG. 6 shows an example of a conventional laminating apparatus.

In the figure, an upper laminate film roll 101a formed by winding a heat-reactive upper laminate film 102a and a lower laminate film roll 101b formed by winding a lower laminate film 102b are disposed in the apparatus main body 100, respectively. ing. Each laminate film roll laminate film roll 101a, 101
