Orca 80-99 Operation and Maintenance Manual

 

 

4.Center the film by sliding it back and forth on the shaft until centered. As soon as the film is unwound from the shaft, the core support will lock the roll into position.

5.Recheck the centering of the film roll with a tape measure.

WARNING:

Normal operation of the Orca 80 laminator involves the application of large amounts of heat to the process materials. The surfaces of the rolls are at a high enough temperature to cause burns if they are touched.

Operators are cautioned not to touch, lean or fall against the rolls of an operating laminator. Do not become unbalanced when working near an operating laminator.

Heating

The following instructions should be employed when heating one or both of the laminating rolls. The procedure is the same for top and bottom:

laminating roller(s) to reach operating temperature. When the pre-set operating temperature has been reached, the machine is ready to use.

Cooling(with optional cooling fans)

The following procedure is the fastest way to cool down the machine. Natural cooling can also be employed:

1.Set the heater switches to OFF.

2.Position the two rear fan banks so that they are tilted to direct air flow at the rolls.

3.Set the Laminator Roll Control to the DOWN position.4.Set the Forward/Reverse switch to the FORWARD position.5.Set the speed control to 5 fpm (150 cpm).6.Let the machine run until the laminating rolls return to room temperature.
1.Set the heater switch to ON.

2.Adjust the temperature controller for the desired operating temperature using the controller push bottoms.

For the Syrlec type controller use the up and down arrows to adjust the set point. Hold down the desired arrow until the correct set point is achieved.

For the CAL3200 it is necessary to press the * button at the same time as the up or down arrow to adjust the set point temperature.

3.When heating the rolls, keep the top roll down and turning at a moderate speed to prevent uneven heating.

4.It will take approximately 25 minutes for the
Paper Tips

1.Always cut the leading edge of a print straight so they can be fed perpendicular to the laminating rolls.

Process Control Charts

Chart 2-1 and 2-1B show a blank set of process control charts for the ORCA 80. These charts are where you record the way you thread film through the machine’s rolls and idlers (called webbing) and the setting of controls and switches for each product and process.

GBC Pro-Tech laminators respond in a very accurate and repeatable manner. The charts provide a way to set up each time, every time, for repeatable performance by assuring all controls are set to optimum.
