“OPERATING THE MACHINE” CONTINUED
After a few sealed trays have come off the end of the machine, check to see if the film is
centered from side to side on the trays. If it is not, the film roll needs to be moved to one
side or the other on the film mandrel. There are thumb screws in the stainless steel
collars on each side of the film mandrel. First loosen the thumb screw on the side which
the film roll needs to move toward and move that collar about one half as far as you think
the film is off center and tighten the thumb screw. Then loosen the thumb screw on the
other collar and move the film roll holder up against the film roll core and tighten the
screw. After getting the film centered on the trays, check to see if the film is sealing to
the trays without excessive wrinkles. If there are excessive wrinkles, it might be that
there is not enough tension on the film roll. This can be adjusted with the three thumb
screws on the plastic film roll holder. Turning the screws clockwise will increase the film
tension. If the film tension is too tight and the film comes off of the roll too hard, back the
screws off by turning anti-clockwise.
