UNPACKING

ChemInstruments has made every effort to ensure that the HL-100, HL-101 arrives at your

location without damage. Check the unit for any damage that might have occurred in shipment. Make

sure that no air lines have been disconnected and that the top roll has not been scratched. Check all

packaging material carefully for individually wrapped accessories. If any damage did occur during

transit, notify the carrierimmediately.

ASSEMBLY

Warning! Due to its weight and size, use two people to move the HL-100/101.

The laminator should be set up on a sturdy bench, which will allow access to both the front and

back of the machine. Some users have found a cart useful in reaching the front and back and also allow

the unit to be mobile. Whether on a permanent bench top or a cart the weight of the unit (160 to 185

lbs.) must be considered.

Warning! Before proceeding with using the HL-100/101, it is advisable to

become familiar with the Key Components of the laminator. These Key

Components and a brief description of their function follow in the next section.

•Carefully remove the kraft paper from the laminating rolls.

•Attach the incoming airline to the machine. Use a female quick disconnect

•Set the laminator's air pressure regulator at 40 PSI for a midpoint starting pressure.

•Plug the laminator into a 120 VAC outlet or 240 VAC if requested as an option.

•The laminator will draw 12 –15 amps at 120 volts.

Warning. Check the amp maximum for the circuit and be sure other

electrical devices on the same circuit do not cause an overload.

•Remove the wooden blocks between the rollers. Save these wood blocks and insert them

between the rolls when the unit is not in use! This will prevent indentations or flat spots from

occurring on the rubber coverings of the roll(s).

•Press the red UP button to raise the pressure roll and remove these blocks.

•If equipped with the optional gap adjusters, create a gap by turning the middle portion of the air

pistons in clockwise direction. The gap adjusters

can be used to create a gap between the rollers

when the machine is not in use. This gap will

assure the top pressure roll is not resting on the

rubber covered silicone roll when not in use thus

preventing an indentation or flat spot from

occurring on the rubber covered roller. (See

Figure 1 for Gap Adjusters location)

•Be sure the roll unwind bar is seated correctly in

the mount.

•If equipped with the optional tension unwind, be

sure the pressure plate is positioned over the pin.

(See Photo 1 Optional Brake Unwind)

The unit is now set up for laminating. See the Temperature Controller Operations manual for

heating instructions.

SAFETY FEATURES

The Hot Roll Laminator should be considered as any other piece of laboratory

equipment. The safety features will not prevent injury. These safety devices will raise the top

roll or stop the drive roll instantly. The objective is to prevent having to use these features. The

following safety steps must be followed.

•Tuck in ties and roll up sleeves. Loose clothing can be pulled into the

laminating rolls and cause severe injury.

•Remove rings and watches. These will only increase your injury if caught in

the laminator.

•Warning! Possibility of crushing/pinching. 1) Do not insert limbs into the nip

area while rolls are rotating. 2) Do not lower the top roll while limbs are in

the nip area.

TRIP WIRE

Located in front of the top-laminating roll. When activated this will cause the pressure roll to rise

and the drive roll to stop, allowing trapped articles to be freed. Test the trip wire by lowering the

pressure roller and moving the trip wire. (See Photo 2)

E STOP

The Emergency Stop button will disrupt all power to the HL-100/101. It will also cause the top

lamination roll to retract to the up position, thus opening the nip. The E Stop is located on the top of the

control cabinet for easy access (See Photo 3). This switch is not intended to be an “on/off” switch and

should not be used as such.

TEMPERATURE CONTROLLER OPERATIONS

The temperature controller is set and tested at the factory before shipment. Auto tuning has

been performed at 250° F. It is ready to begin operating as soon as the HEATER switch is turned on.

(See Photo 3)

Allow the unit 45 minutes to one hour to fully stabilize to the set temperature. This also applies when

changing temperatures. (See Temperature Controller Manual Enclosed).

To change the temperature set point:

•Press the SET/ENT button

•The brightly lit number is the number that will be changed. Use the left arrow button to select

the number you would like to change.

Photo 3 –Control panel

•Use the up and down arrows to change the number.

•Once the new set point (SP) has been entered press the SET/ENT button again to save the new

value. If the set enter button is not pushed the controller will continue at the previous

temperature.

•When no buttons are pressed for a period of one (1) minute, the controller returns to normal

operating mode automatically. Press SET/ENT again to continue changing the set point if

desired.

WARNING: After the heater switch is turned on, the internal temperature of the

heated roll(s) will rise very quickly. The 45 minutes mentioned above is the time

for full roll temperature to stabilize. The surface of the roll will be hot whenever the

heater switch is turned on.

DO NOT TOUCH THE HEATED ROLL(S) AFTER THE HEATER IS TURNED ON!!

OPERATION

THEORY OF OPERATION

ChemInstruments Hot Roll Laminator provides laminating capability with pressure and if desired

heat. Sample material is placed between the laminating rolls where pressure and heat cause the samples

to laminate together.

Warning: Before operating the laminator see page 7 for safety precautions.

LAMINATING PROCEDURE

•Raise the pressure roller (Red UP button), turn temperature controller on and allow the

temperature to stabilize.

•Set the speed as necessary for your material. Turn the motor OFF after the speed is set.

•If the material is in roll form place it on the unwind stand with the heat activated side up and the

uncoated side to the roll. Thread the material over the idler roll and through the pressure nip

gap. Place the other material under heat-activated substrate.

•If you are working with hand sheets lay one on top of the other and place one end of the

assembly in the pressure nip gap. Check to be sure the coated side is between the sample

substrates.

•After the material is positioned to be laminated, push the DOWN green button and turn

the motor switch to the ON position.

•As the sample moves through the laminating nip, it may be necessary to guide the sample over

the rear sample platform.

•When the lamination is finished, turn the motor to the OFF position and press the UP (red)

button to release the pressure.

•Insert the wooden blocks between the roller shafts when the machine is longer in use. Do not

allow the rolls to rest together. This will cause flat spots to develop on the rubber roll.
