Application Techniques (Refer to
Diagram A)
Pre-marking:
Using 200-250 ft. (60-70 m) of light rope, chain or
thin wire cable for a guideline, mark the skip
sequence on the chain to be followed. Example:
A sash chain marked to the proper sequence with
1-inch (2.54 cm) spiral key rings.
Example: For a 10 ft. (3 m) skip line and a 30 ft.
(9 m) space (10-30 sequence):
1) Mark point (A), the beginning of the first skip
line, about 8 feet (2.44 m) from the beginning
of the chain to line up applicator.
2) Measure 10 ft. (3 m) and mark point (B), the
end of the skip line.
3) Measure 30 ft. (9 m) and mark point (A), the
beginning of the next skip line.
4) Repeat steps 2 and 3 throughout the remaining
length of the guideline so that the last mark is
at point (A).

Product Width and Spacing
Several combinations of tape widths and spacing
can be applied using the MMHTA-18. Combina-
tions of solid and skip lines may be applied simu-
taneously. The 3M™ Manual Highway Tape
Applicator can be used to apply all Stamark and
Scotch-Lane pavement marking tapes at maximum
standard roll lengths. NOTE: If special ordering
tape, the maximum roll diameter cannot exceed 20
inches (50.8cm) if the material is to be applied
with a MMHTA-18. Consult your 3M representi-
tive to determine the availbility of the MMHTA-18
in your area.
Operation
The tape applicator can be operated by one person.
The following application rates are based on
asphalt paver speeds of 25 - 50 ft./min. and a
walking speed of 100 ft./min.
10:30 Skip 750 ft./hr.
15:25 Skip 1125 ft./hr.
Solid Line 1500 ft./hr.
Solid / Skip (NPZ) 2500 ft./hr.
Double Solid 3000 ft./hr.
Overall Average 1000 ft./hr.
NOTE: The application rates shown are intended
as guidelines and may vary with project condi-
tions.
Procedure for Application of Pavement
Markings
Load the tape and thread it over the 2-inch (5.08
cm) diameter aluminum roll, adhesive side up (See
Figure 2). Feed the tape through the CLAMP to
the CUTTER PLATE. Adjust the GUIDE BARS at
the sides of the tape rolls to hold them securely in
position. The guide bars should be adjusted to
allow the roll to rotate freely, but not move side to
side. Stamark pavement marking tapes can be
ordered with the adhesive side of the tape wound
inward or wound outward. Both types of rolls will
work with the MMHTA-18; however, the tape
wound adhesive side out is recommended. The
tape wound adhesive side out will develop a natur-
al curl that positions it to curve toward the silicone
applicator roll as it passes through the cutting
plate.
CAUTION: Do not activate the cutting knife with
the foot pedal while threading tape.
