Adjustments
Tape Width
The tape drum is assembled at the factory for 3/8
inch [9 mm] or 1/2 inch [12 mm] wide tapes. For
5/8 inch [15 mm] tapes the retainers must be moved
to the secondary position on the tape drum. This is
done by removing the two screws and relocating the
retainer, shown in Figure 2-3, then replacing and
securing the screws.
Tape Web Alignment
The tape drum assembly controls tape web
alignment in the applicator. Adjust the tape drum
assembly so the tape web is dispensed, centered on
the buffing rollers.
Tape Drum Tension
The tape drum assembly provides a preset tape roll
tension to control over-travel. The tape drum
tension requires no further adjustment.
Tape Tension Roller
The tension roller assembly, shown in Figure 4-1,
provides a preset tension to the tape web. No
further adjustment is required. If the tension roller
assembly is replaced or comes out of adjustment,
make adjustment as follows to obtain tension to the
tape web: turn the lock nut, located behind the
tension roller assembly, counterclockwise to
increase tension, clockwise to decrease tension.
V-8 Valve Adjustment
There are two lines scribed on the actuator button of
the valve. Correct adjustment of valve places the
middle of these two lines at the edge of the actuator
button housing when feed assembly is at top of
travel (see Figure 5-1). Loosen valve adjustment
screws (2), slide valve up or down to obtain this
adjustment and tighten screws. Be sure feed
assembly is held at top of travel when making valve
adjustment.
Air Flow Controls
There are four air flow control valves on the S-867.
Two each for the tape feed air cylinder and tape buff
air cylinder. These are preset at the factory. Should
adjustment be necessary, turn knob counterclockwise
to increase cylinder speed and clockwise to decrease
cylinder speed. The factory setting of each speed
control valve is as follows: F1 - 1 turns open,
F2 - 1-1/2 turns open, F3 - 1-1/2 turns open,
F4 - 1-3/8 turns open.
