Adjustments
This section is presented in two parts: the first part outlines adjustments for the L-sealer;
the second part outlines adjustments for the shrink tunnel section of the machine.
Solid state temperature controllers for the L-sealer and shrink tunnel look similar but
have slight differences in the display and number and function of programming buttons
(five buttons for the L-sealer temperature controller, versus six buttons for the shrink
tunnel temperature controller, for example) for making settings. Be sure to look carefully
to consult the instructions that are applicable to the controller you are working with.
L-Sealer Adjustments
Element Pulse Switch Adjustment
The sealing cycle should not begin until the seal head is within one-quarter-inch (¼
”) or
less of the film to be sealed. If the magnets energize before the head is within one-
quarter-inch of the film, loosen the locknut and turn the screw (located at the rear of the
side seal bar) up slightly (counter-clockwise as viewed from above). Adjustment has
been set correctly when the magnets are energizing just as the seal bar comes into
contact with the lower magnet pads.
Electromagnet Position Adjustment
All magnets have been factory adjusted for equal sealing pressure throughout the
length of both the front and the side seal bars. If an adjustment is required, however,
use the following procedure.
1. Disconnect the L-sealer power plug from the electrical power source.
2. Loosen the lower magnet screws on all of the lower magnets so the magnets
settle to the lowest position in the mounting slots.
3. Lower the L-sealer operating handle fully and lift the lower magnets to within the
thickness of a dime from the holders.
4. Re-tighten the mounting screws securely to retain the proper adjustment.
Seal Pad Pressure Adjustment for Head Return Cylinder
Uniform pressure between the sealing elements and the sealing pads must always be
maintained in order to obtain an even seal and to prevent heating-element hotspots and
premature burnout. The adjustment should be checked periodically and should always
be checked when sealing gaps occur.
