Laminating device

1. A laminating arrangement system comprising:

a laminating roller;

a temperature detecting arrangement operable to detect a temperature of the laminating roller; and

a processor operable to

run a timer with a predetermined time period after which the laminating arrangement will timeout and shut down if no laminating has been done,

receive a signal from the temperature detecting arrangement indicative of the temperature of the laminating roller,

determine a temperature drop of the laminating roller,

compare the temperature drop of the laminating roller to a predetermined temperature drop, and

reset the timer if the temperature drop of the laminating roller is equal to or greater than the predetermined temperature drop, indicating that laminating has been done.

2. The laminating arrangement system of claim 1 , wherein the temperature drop of the laminating roller is determined as a rate of temperature drop and the predetermined temperature drop is a predetermined rate of temperature drop.

3. The laminating arrangement system of claim 2 , wherein the predetermined rate of temperature drop is at least 0.7 degrees Celsius per second.

4. The laminating arrangement system of claim 1 , wherein no switch or sensor is provided on the laminating arrangement system for detecting an insertion of laminating medium into the laminating arrangement.

5. A laminating arrangement system comprising:

a laminating roller;

a heat source for heating the laminating roller;

a temperature detecting arrangement operable to detect a temperature of the laminating roller; and

a processor operable to

receive a signal from the temperature detecting arrangement indicative of the temperature of the laminating roller,

determine a rate of temperature increase of the laminating roller based on the signal from the temperature detecting arrangement,

compare the determined rate of temperature increase to a nominal rate of temperature increase expected for the laminating roller, and

if the determined rate is below the nominal rate, take action to prevent damage to the laminating arrangement caused by excessive heating of the laminating roller.

6. The laminating arrangement system of claim 5 , wherein taking action to prevent damage to the laminating arrangement includes turning off the heat source.

7. The laminating arrangement system of claim 5 , wherein taking action to prevent damage to the laminating arrangement includes turning on a fan.

8. The laminating arrangement system of claim 5 , wherein taking action to prevent damage to the laminating arrangement includes activating at least one of a visual and an audio indicator for a user.

9. The laminating arrangement system of claim 5 , wherein the nominal rate of temperature increase expected for the laminating roller is for a warm-up period of the laminating arrangement.

10. The laminating arrangement system of claim 5 , wherein the nominal rate of temperature increase expected for the laminating roller is for an operation period of the laminating arrangement.

11. A laminating arrangement comprising:

a laminating roller;

a heat source for heating the laminating roller, the heat source being powered by an AC power supply; and

a heat source intensity control system for controlling the intensity of the heat source, the intensity control system including

a processor, and

a triode for alternating current communicating with the processor, the triode for alternating current being turned on and off by the processor to control the AC power supply to the heat source to vary the intensity of the heat source.

12. The laminating arrangement of claim 11 , wherein the heat source intensity control system further comprises zero cross detect circuitry for detecting a zero cross point of the AC power supply, the processor communicating with the zero cross detect circuitry.

13. The laminating arrangement of claim 11 , wherein the heat source is a halogen bulb.

14. The laminating arrangement of claim 11 , wherein the heat source intensity control system is operable to vary the intensity of the heat source from thirty percent intensity to one hundred percent intensity at ten percent increments.

15. The laminating arrangement of claim 11 , wherein the processor turns the triode for alternating current on and off in a substantially evenly-distributed manner over a period of cycles of the AC power supply to achieve substantially even heating of the laminating roller.
