Abstract:
1. A sheet laminating apparatus with an instant heat control function to laminate a sheet article between two pieces of thermoplastic films, said sheet laminating apparatus comprising: a first cylindrical roller having a first roller surface; a second cylindrical roller having a second roller surface, wherein said first roller surface is contacted with said second roller surface, and said first cylindrical roller and said second cylindrical roller are rotated in opposite directions for pressing said sheet article and said thermoplastic films that are transported between said first cylindrical roller and said second cylindrical roller; a first long metal sheet arranged beside said first cylindrical roller and separated from said first cylindrical roller by a first gap, thereby transferring heat to said first cylindrical roller; a first heat-generating case contacted with said first long metal sheet for generating heat to said first long metal sheet; a second long metal sheet arranged beside said second cylindrical roller and separated from said second cylindrical roller by a second gap, thereby transferring heat to said second cylindrical roller; a second heat-generating case contacted with said second long metal sheet for generating heat to said second long metal sheet wherein said first long metal sheet is enclosed by said first heat-generating case, and said second long metal sheet is enclosed by said second a contact sensor contacted with said first roller surface of said first cylindrical roller for detecting a temperature of said first roller surface; and a controller connected to said contact sensor, said first heat-generating case and said second heat-generating case for controlling temperatures of said first roller surface and said second roller surface.
