OPERATION
The way to thread film:
Adjust the position of the connector
shaft through pulling the sphere-type
handle(the black sphere on the two side
of connect shaft) to locate it at the
lowest point of the “ ”groove
Thread the film across between the
rubber roller and the connector shaft
pass the lower and upper edge of the
film under and over separator
respectively
In according with customers ’s
request ,you can adjust click pulley to
stitch the film.If so , please move the
connector shaft to the right of the “ ”
groove to make spike press the rubber
roller closely
Draw the leading edge of the film from Right
to Left into the chamber area and cross the
sealing blade. Ensure the top and bottom
leaves of film around the dividing table are
equal in length, and operate the hood to
produce a seal on the Left –hand end of the film
Remove the waste film-cut off by this operation
from inside the chamber
Place your product on top of the dividing
table and inside the film –against the fold
at the back. and the seal at the Left–hand side
Draw product and film into the chamber and
place approximately 10mm or 15mm from the
front and side seals .Operate the hood and the
shrink/seal process is carried out automatically
with the hood opening on completion of the
cycle.
If the film is not fully shrunk –increase
MAGENT TIMER and /or TEMPERATURE
until
good results are obtained.
If the film burns or punctures-reduce
TEMPERATURE and/or MAGENT TIMER
until
good results are obtained.
FILM SIZE/ADJUSTMENT
Select a suitable film width for your
Product (-usually WIDTH OF PRODUCT (front
To back) and HEIGHT OF PRODUCT + about
75mm), Fit the film on the reel carrier with the
folded side to the rear of the machine .and
thread as described previously. The front
OPEN side of the film should be about 50mm
Over the front seal blade, and the DIVIDING
TABLE should be positioned so that inside the
film it is about 20mm from the folded edge.
DO NOT attempt to seal and shrink if there
is any tension on the film as the hood is
closed -the pack will split open as it shrinks.
ALWAYS allow the film to be relaxed as the
seal takes place.
If the film BALLOONS and does not shrink
fully around your product-then the machine is
making too good a seal !Use one or both sets
of perforator wheels on the reels carrier during
the shrink process
TAKE CARE –THE PERFORATOR
WHEELS HAVE SHARP SPIKES which are
behind the film during operation but which are
EXPOSED DURING ADJUSTMENT AND
FILM THREADING
