SHRINK TUNNEL
 The Non-Stick Mesh conveyor belt (1) is an integral part of the
shrink wrapping unit. Heat is circulated to the underside of the
belt, and adds positive shrink on the bottom for a more attractive
package. Tunnel Belt Conveyor Speed is adjusted using the
Express Control Dials.
AIR VENTING
 Air venting the film is required for most shrink applications. The
L Sealer is equipped with a standard perforating roller for
venting the film.
 The perforating roller (2) is used to make a series of small holes
continuously as the film is being drawn from the roll during
normal packaging operation, and is located in the film cradle
before the loading platform.
BALANCED MAGNETIC HOLD DOWN
 A magnet plate (3) on the front of the sealing arm and a magnet
(4) on the front of the sealing area are used to insure an even,
consistent seal along the sealing pad. The position of the
magnets have been engineered to apply the maximum seal
pressure, and provide a clean seal every time.

THREADING THE FILM
 Place a roll of center folded film on the rollers with the open
side of the film toward the operator (1). The cradle is
adjustable to accommodate various size packages with the
same width of film up to 17 inches wide. Thread the film as
shown in the threading diagram on the machine below (2).
 Place the product to be wrapped in the lower corner of the
sealing area (3), then loosen the knobs (4) under the film
cradle and position the cradle so that the folded edge of the
film is even with the back of the package to be wrapped (5).
 Re-tighten the knobs (4).
 If the correct width of center folded film is being used, this
position will provide a minimum of 2 inches of film for trimming
across the front of the sealing area (6).
 This is a general starting position and adjustments can be
made to provide for adequate film around the package for
shrinking and conservative use of your film.
PRELIMINARY SETUP & ADJUSTMENTS

7
Revised 2019
ADJUSTING THE SEALING PLATFORM
To insure a neat looking finished package, the sealing platform (1) can
be adjusted so the seal made by the L Bar will be at the center of the
vertical (profile) dimension of the package to be sealed. The system is
available with two styles of sealing platforms: static or Silicone Fabric
seal conveyor (2).
Although frequent adjustment is not required for most production
applications, the adjustable platforms permit quick change over for
products with different profiles and provides positive locking for stability
under loads.
To change platform positions:
STATIC PLATFORM AND ROLLER TRAY
The platform position is easily changed by inserting fingers in holes (3)
and after lifting slightly, slide platform to the left (towards the tunnel),
releasing projections from the notched brackets (4) in the right side of
the sealing area.
With the platform held towards the left (tunnel side), raise or lower the
platform to the desired height. Then insert the projections in the right
side notches first, and slide the platform as far forward right as
possible.
SEAL CONVEYOR
The knob in the front center of the sealing area (5) adjusts the
conveyor to any desired height. Clockwise will raise the conveyor,
counterclockwise will lower the conveyor.
PRELIMINARY SETUP & ADJUSTMENTS

Revised 2019
L SEALER OPERATION
Due to the various types and gauges of shrink films, the sealing temperature control will require adjustment to obtain the
optimum setting for the film being sealed. Always use the minimum setting that will provide a satisfactory seal to achieve
maximum sealing wire and/or knife blade life and minimize replacement of Non-Stick tape and sealing pads.
SHRINK TUNNEL OPERATION
As with the L sealer, the various types and gauges of films will require some experimenting with the temperature setting of the
shrink tunnel and the conveyor speed to obtain the desired shrink.
Because some time is required for the tunnel chamber to adjust to a temperature setting change, it is recommended that the
conveyor speed adjustment be used to change the time exposure of the package to the available heat for shrinking. If after
achieving the desired shrink of the package the conveyor is running too slow for required production, increase the temperature
setting of the chamber.
When the chamber has stabilized, increase the conveyor speed. It is recommended that for the most economical operation, the
tunnel temperature be maintained at the lowest setting compatible with the shrink film being used and your rate of production.
OPERATING PROCEDURES

9
Revised 2019
USE CAUTION WHEN CHECKING THE SEALING CYCLE AS SOME
SURFACES ARE HOT. THE CYCLE FOR THE SEALER CAN ALSO BE
CHECKED WITH THE POWER OFF.
OPERATING PROCEDURES
MACHINE CONTROLS
 There is two controllers for the operation of your machine. The Main Control Panel (1) will control Seal Time, Dwell Time,
and Conveyor Speed. It will also control Seal Conveyor Run Time if the HSE-100 is equipped with a Seal Conveyor. The
Tunnel Temperature Controller is located on the top right portion of the tunnel. Use the temperature dial as a reference
point as actual tunnel temperature may vary slightly. The power indicator light (3) will illuminate when there is power
running to the tunnel.
 It is essential that related functions be properly controlled to provide the sequence necessary for the satisfactory
performance of the L Sealer and Shrink Tunnel. These control settings should be made before operating this equipment.
 Seal Time: (0-2 seconds) The amount of time the sealing
wire is energized for while the magnet holds down the seal
arm down.
 Dwell Time: (0-2 seconds) The amount of time the seal
arm is held down after the seal time has expired and seal
wire has de-energized.
 Conveyor Speed: (0-10 seconds) Controls the speed both
the tunnel conveyor and seal conveyor will run at.
 Seal Conveyor Run Time: (0-10 seconds) Controls how
long the seal conveyor will run after the seal arm is raised.
ADJUSTING OF THE SEALING CYCLE
 Located at the back of the sealing area is an adjustment screw type
actuator and button (4) which starts the sealing cycle as the sealing
arm is brought into sealing position. This is a function adjusted at the
factory but if adjustment is necessary, proceed with the following
steps:
 The timed impulse must start when the seal arm (5) is approximately
1/16 of an inch (or the thickness of a quarter) above the sealing pad
(6).
 Bring the arm down slowly toward the sealing position, the wires will
begin heating, or the magnet will engage when the sealing process
has begun.
 If the arm is too high from the sealing pad (over 1/16 of an inch),
adjust the screw (7) away from the Microswitch (4).
 If the arm reaches the sealing position without actuating the sealing
cycle, adjust the screw closer to the microswitch to actuate at 1/16 of
an inch above the sealing pad.

There are three steps in creating the package on the shrink
wrapping system: wrap, seal and shrink.
WRAPPING
The operator places the product to be wrapped on the package
platform (1) inserting it between the center fold film (2). Holding the
product firmly with the right hand (3) and the corner of the film with
the other hand (4), move the product onto the sealing area.
SEALING
The package is placed in the lower right corner of the sealing area
(5), allowing for sufficient film margin on the side and front of the
package (about 2 inches) for adequate shrink. The sealing arm is
lowered into position (6) which actuates the sealing cycle. The two
open sides of the film are sealed completing a bag around the
product and leaving the end of the film sealed, ready for the next
package.
SHRINKING
The sealed package in the loose film (7) is manually moved out of
the sealing area and onto the conveyor belt. If equipped with a
sealing conveyor, the package will automatically be taken into the
shrink tunnel. The package is conveyed through the shrink tunnel
and recirculating, heated air shrinks the film, creating a clear, tight
package (8).
