The cylinder to be covered must be flat faced and free from all
grease, oil and old coatings. This can be accomplished by sanding
with 125 grit sandpaper and wiping with a non oil solvent such as
MEK or ACETONE. When clean, use a carpenter's square or level to
make a reference line across the face of the roll. This is where
the roll covering will be started and will enable the technician to
keep the PTFE covering straight during application
2 Cut a piece of the
roll covering equivalent to the circumference of the roll plus 2
inches, keeping ends as square as possible. Peel back release paper
liner and attach it to a 3" cardboard core with masking tape, to aid
in handling during application.
3 Apply the adhesive edge of
the Fluorglas to the reference line. Wind release paper on to the
cardboard core as the Fluorglas is applied. At the same time
another person should press or wipe Fluorglas material into place
with a clean cloth. This helps prevent the formation of creases and
air bubbles. Trapped air bubbles can be removed by slitting the
bubble with a razor blade and pressing down firmly to eject the
air.
4
After the complete circumference
has been covered with Fluorglas, overlap the ends 2 inches. Then make
an incision along the entire length of the seam, cutting through both
layers of material.
5 Remove the top layer of
the cut material
6 Carefully peel back
the Fluorglas and remove the bottom layer of the excess material.
To prevent adhesive contact of the waste material and the roll
covering, twist the strip as it is pulled away from the
cylinder.
7 Using either a plastic
comb or another plastic tool, start at the center of the seam and
smooth outward to make a clean butt splice.
8 Apply the second section
and following selections in the same way, overlapping the edge as
well as the ends by 2 inches. This will allow a clean butt seam when
material is smoothed as previously described. Continue this procedure
until entire surface is complete
