After finding the correct combination for speed and temperature of lamination, these
values may be stored in short-term memory by pressing the "AUTO CONTROL" button
(Figure 7-15). Operation in this mode is signaled by the LED (Figure 7-16). The automatic
operation mode may be terminated by repeated pressing of the "AUTO CONTROL" button.
The processor of the control of the equipment responds to gradual and sudden loss of
temperature on the roller (caused by draught or by accident on the bearing or by too high
speed when the heating body does not have sufficient time to heat the roller) by lowering the
speed of the motion. The automatic operation decreases the speed until the heating body
equalizes the heat losses and the temperature starts to increase. Then, automatically, the speed
of the lamination increases again. The automatic mode should be used primarily when
connecting the laminator to automatic feeding machine.
A typical situation for using the AUTO CONTROL button is an accident on the heating spiral
within lamination roller or on the breaker of the hearing body. During lamination in the
AUTO CONTROL mode with the feeding machine, the laminator (when the heating is not
functional) stops automatically sooner than any damage on the laminated sheets or on the
laminator occurs.
Relationship of the speed of the lamination and the difference between temperatures is listed
in the chart and is calculated in line with the following formula:
