Van Der Stahl LOS NT Series, Руководство по эксплуатации

Страница: 13 / 64

LOS-NT/NTW series is installed with a nozzle, which
moves back and forth, as well as the sponge rubbers at
the upper and lower seal jaws to clamp the nozzle. After
vacuuming, the nozzle in the front position moves
backward and the sealing operation starts at the same
time.
When the gas-flushing operation is selected, the gas-
flushing starts after vacuuming. Vacuuming and gas-
flushing will be repeated at the set times, and then the
sealing operation starts.
Sealing angle can be adjusted from horizontal to
vertical position at any position by turning the knob
located on the right side of machine. The head height
can be adjusted as well easily by pushing up/down
buttons on the side of the machine.
Please refer to “
7-7 Adjusting the sealing height ” and
“
7-8 Adjusting the sealing angle
” for the detail.
※ NT series is suitable for packaging that requires
vacuuming of up to -80kPa.
※
For the NTW series, vacuuming is conducted
through the use of an ejector, powered by the
compressed air. It is effective for vacuum-
packaging liquid and powder contents.
Vacuuming speed is 3 or 4 times faster than that
of the vacuum pump type.

The impulse sealer is a machine that sends strong electric current quickly to the thin ribbon heater, which
presses against the film and instantly heat-seals the package. Though this machine yields superior quality
sealing, it is not compatible with films thicker than that indicated in the diagram below, sponge-like sheets,
and materials that are not able to withstand high heat. In addition according to difference of film thickness
and martial, the heating temperature is different. Please verify the optimum sealing conditions before
operation.
