3. Review the threading diagram
Remember, the shiny side of the film
must always go against the shoe. The dull (adhesive) side must face
away from the shoe.
With the top roll of film centered on the mandrel and the shiny side facing
down, pass the film under the lower idler, over the top idler, and then drape it
over the top heat shoe. You are now ready to load the bottom supply roll
mandrel.
4. Load the bottom roll of film onto the mandrel in the same manner as the
top roll. Remember, the
shiny side of the film must always go against the
shoe
.
The dull (adhesive) side must
face away from the shoe
. Make
sure the two rolls are aligned with each other before going to the next step.
Pass the web under the idler bar near the bottom heat shoe. Use extreme
care if the heat shoe is already heated up. Pull the bottom web up and drape
it over the top web. When the machine is hot, the two webs will stick to each
other. If threading while cold, use tape to hold the bottom web in place.
