7.0 GENERAL INSTRUCTIONS

7.1 GENERAL:

Product is presented to the machine by manually placing it on the package tray. The operator

then pulls the product and film into the seal area. The operator then pulls the sealing arm down

activating the magnet and starting the seal cycle. The plastic is sealed and cut. The time/temp

board releases the magnet, releasing the seal head. The package is then fed into the shrink tunnel

There are two timers utilized by the machine program.

1) A time/temp timer is used to control the heating of the sealing wire.

2) Optional conveyor timer which sets the length of time the power takeaway conveyor

is on.

7.3 GENERAL MACHINE CHANGEOVER:

After assembly and locating the machine, place the roll of centerfold film on the film rollers with

the open end facing toward the operator. The film should be positioned on the rollers so that 1

1/2" to 2" is available for selvage (scrap) across the front of the sealing area. To secure proper

tension on the film use the film brake located on the back of the film cradle. Turn the


10

thumbscrew clockwise to increase tension. Use minimum tension for easy film release. Once

the brake is set, place the top layer of the centerfold film over the package loading platform and

the bottom layer under the platform. The pin wheel perforators are generally set to place the

perforations on the center of the package. Adjustment of the platform allows for narrower

packages. This adjustment is accomplished by lifting the adjustment handle under the platform

(on the front side) and sliding the platform to the desired position, after which the adjustment

handle is returned to the locked position.

Adjust the height of the sealing platform (package tray) so that the seal pad is centered vertically

on the package. On a standard machine, lifting the platform using the four finger holes, up and

toward the left makes adjustment. The platform is then free to move to one of the positions.

With a power takeaway conveyor, adjustment is accomplished by turning the knob below the

machine.

Adjust the time / temperature cycle to a preliminary setting of "5” on the operator panel scale.

This setting may require further adjustment depending upon the type and thickness of film being

used. For best component life ALWAYS USE THE MINIMUM SETTING THAT WILL

PROVIDE A SATISFACTORY SEAL.

NOTE: If film used is PVC with a sealing wire system, it is recommended that the element wire

be covered with either 3-mil Teflon tape 1/2" wide or a Teflon sleeve. Remove the film clamps

if sleeve is chosen. For PVC, an optional seal pad is available, 77-3587.

Set the tunnel conveyor to a preliminary setting of “2” on the operator panel scale.

Set the tunnel temperature to a preliminary setting of 325F on the tunnel’s operator panel. It will

take approximately 20-30 minutes to reach temperature.

After the initial package has been run through the heat shrink tunnel, the following adjustments

may be made:

1.) Increase or decrease the thermostat setting.

2.) Increase or decrease the conveyor speed.

Due to the various types of shrinkable films, room temperatures and voltages, you may have to

experiment with various temperatures and conveyor speeds, to get the desired shrink. Your film

supplier is familiar with this type of equipment and will be helpful in determining the best

settings for the film you are using.

Note: For more detailed information on changeover procedures see Section 10.0

10.0 MACHINE MAINTENANCE

10.1 GENERAL:The machine should be inspected on a timely basis to ensure all is functioning well and in good

working order. There is not much required to keep the machine running trouble free. The most

important area, as mentioned before, is the seal head. The following are recommendations for

preventative maintenance on the machine to keep it performing well over an extended period.

10.2 MAINTENANCE TIPS:

1. With the machine idle, run a burn off cycle.

2. Inspect the Teflon tape on the seal pads and replace as required according to the instructions in

Section 10.3.

3. Inspect the conveyor belts for wear and misalignment. If the belts are not tracking properly,

adjust the idler rollers to realign the belts. Replace worn belts as needed.

4. Lubricate all chain drives every 160 hours of operation with a bearing grease or chain

lubricant.

5. General cleaning of the machine wiping down the conveyor belts and other flat surfaces to

remove any dirt. Do not use any type of belt dressing on the conveyor belts.


18

10.3 SEAL PAD MAINTENANCE.

Refer to section 12.3 “SPARE PARTS LIST” for replacement part numbers.

If the rubber pads need to be replaced (i.e. grooved), remove the old tape and pull the old

pads out. Ensure the pad trays are clean of debris; lay the new pads in place. The pads

are covered with two strips of Teflon tape, which provide the seal surface. The first strip

down is 2” wide and should cover the seal pad. The second is a 1/2” wide strip and is run

the length of the seal pad on centerline. This is the strip, which provides the backing to

the sealing wire. The Teflon strips should be kept clean and free of wrinkles. When

replacing the tape, replace both pads together. The 2” strip of tape should be placed on

both of the pads with the side pad strip cut to butt up against the end pad. DO NOT

OVERLAP THE TWO. The 1/2” strips should then be placed down, again butt the end

of the 1/2” side strip up to the edge of the 1/2” end strip. This will ensure an even surface

for the sealing wires to meet and seal the plastic.
