<p>An improved laminator with a novel heating control system is disclosed for particular employment with laminating packets formed of an article to be laminated positioned between top and bottom leaves. When the packet is aligned in a ready position within the laminating machine, heating elements in a heating zone of the laminating machine are activated while the packet is stationary. When the heating zone attains a first temperature, movement of the packet is initiated in the heating zone. During passage through the heating zone, when the heating zone attains a second temperature, power to the heating elements is cycled so as to maintain the second temperature substantially constant. Also, to further minimize temperature overshoot, power to the heating elements is temporarily removed when the first temperature is attained. With the system of the invention, the dual problems of temperature overshoot and insufficient lamination of lead ends of the packet is avoided.</p> |
