The tape drum friction brake on taping
head is pre-set for normal operation to
prevent tape roll over travel. Should
tension adjustment be required, turn self-
locking nut on shaft to vary spring
compression. Turn nut clockwise to in-
crease braking force, and counterclock-
wise to decrease braking force.
Adjust brake to minimum tension to
prevent tape roll over travel.
Note
– Excess braking force will cause
poor tape application and may lead
to tape tabbing on trailing tape leg.
