Applying Mechanism Spring

The applying mechanism spring
(Figure 5-3), controls applying/
buffi ng roller pressure on box and
returns the mechanism to reset position.
The spring pressure is pre-set but is
adjustable.
To determine Spring Tension Setting,
See Figure 5-3.
One-Way Tension Roller - Figure 5-4
The main tape tension adjustment is
made at the one-way tension roller.
The one-way tension roller aff ects the
amount of tension or force required to
pull the tape. This adjustment will aff ect
wipe-down and cut-off characteristics.
The trouble shooting section of this
manual will help diagnose improperly
adjusted tension. To increase tension,
tighten the center nut clockwise and
to decrease tension turn the nut
counter-clockwise.
Tape Roll Brake - Figure 5-5
The nut and spring on the tape roll hub
controls an adjustable friction brake
that should be used to prevent over-
spinning of the tape roll and adjusted to
provide a minimum of resistance against
tape pull. To increase tension, tighten
the center nut clockwise and to decrease
tension turn the nut counter-clockwise.
Figures 5-5 and 5-6 - A yellow sticker
showing 3 indication levels can be used
with circular plate below the center nut
to determine tension levels.
0-1: Light / 1-2: Medium / 2-3: Strong
Important: Tape tension is aff ected by a variety of
factors. Incorrectly set tension levels
can result in poor tape application.
The troubleshooting section of this
manual describes potential tension
problems and fi xes.
