84-55 USING JIGS
2.0 LOADING OF MATERIAL INTO THE JIG (E.G. COLLAR)
1. Open jig and position lower ply of cloth to the jig location marks.
2. If the jig has a filling bar (i.e. middle section) close this on the lower ply of cloth.
3. Position the upper ply of cloth to jig location marks.
4. Close the top plate of the jig.
5. Jig is now ready to insert into machine
2.1 PROGRAM SELECTION
This machine has a LCD display control with function keys. Any program editing is possible
with the help of keys. Programming instructions have neen explained in detail in section 5.
2.2 LOADING JIG TO THE MACHINE
The 84-55 has two start options, Manual start or Auto start. In Manual start mode the green
start button must be pressed to start the machine. In Auto start mode, the machine will begin
automatically once the jig has been loaded safely.
2.2.1 MANUAL START
a) Slide the loaded jig towards the needle, lining up the start position approximately ½”
(13mm) behind the needle.
b) Push the jig over the raised flap in front of the needle plate.
c) As the jig is pushed to the right, the jig flap will drop to its normal position.
d) If the jig is located correctly, the raised “D” shape of the needle plate will locate in the track
of the jig.
e) Pull jig back to closed end of track. (Double jig should be pulled back so jig contacts presser
foot).
f) When the jig is loaded, press the green start button on the table top; the sew cycle will begin.
g) At the end of the cycle the jig will be ejected (or in case of a double jig, wait for the operator
to reposition the jig for second half).

USING JIGS
2.2.2 AUTO START
The auto start function may not be used
on double jigs.
e) Pull jig back to close end of track. At
this point the proximity sensor in the
needle plate will detect the metal tab in
the jig. See fig.2.0.
f) If the jig is loaded correctly and both
the snubber switch and photocell have
been activated, the machine will start
automatically. See fig.2.0.
g) At the end of the cycle, the jig will be
ejected.

USING JIGS
2.3.0 AUTO STARTMETAL TAB
The metal tab is located at the start of
track. A Tufnol locating patch holds it in
place. Set the metal tab to activate the
proximity sensor 2mm before the raised
“D” makes contact with the end of the
inner track.
This setting may have to be altered if the
start of the sew seam is incorrectly posit
ioned.
2.3.2 PHOTOCELL TAPES
The tapes on the surface of the jigs are
used to trigger the programs in the
controller. See section 5 for full
instructions on program editing.
Figure 2.2 shows a simple slow sew corner
jig, with dense in and out of the corners.
Each tape sends a signal to the control box
to activate a particular function.
2.3 JIG SET UP
Before the jig can be used the auto start
metal tab and all the photocell activating
tapes must be positioned correctly.
2.3.2 FLYFRONTS
The AMF Reece controller will allow the
use of fly front jigs. To set up the jig for
this operation, position tapes are shown in
figure 2.3 and refer to section 5 for
programming instructions.

Adjustment of Presser Pressure
Turn the presser regulating screw clockwise to
increase, and counterclockwise to decrease.
Be sure to tighten the nut after adjustment.
A foot pressure of approximately 1,5 to 2 kg
will give best results on all materials.
3.11EMERGENCY STOP
This is activated by pressing the Stop Button. This will activate the Emergency Stop Sequence.

MECHANICAL SETTING PROCEDURES
4.0 INTRODUCTION
This section deals with the mechanical settings for parts not found on standard Juki head.
4.1 JIG DRIVE SETTINGS
Figure 4.0 shows the jig drive assembly. On the 84-55 a jig may be driven continuously or with
an indexed motion. The settings for these two styles of motion are given in separate sections
below. Any settings common to both types of motion are also given in separate sections.
4.1.1 COMMON SETTINGS
4.1.1A DRIVE WHEEL CYLINDER
The rod end bearing ( item 8, figure 4.0) should be set so that when the cylinder is fully
extended the drive wheel is taken 3mm past its point of contact with the jig.
CAUTION :
IF THE DRIVE WHEEL TRAVELS TOO FAR, IT WILL DAMAGE THE PHOTOCELL IF THE MA-
CHINE IS RUN WITHOUT A JIG.
4.1.1B DRIVE WHEEL SURFACE
The surface of the drive wheel must not be contaminated with any lubricant or silicon Aerosols
etc. Such contamination will affect jig feeding. If contamination occurs, clean the tapered
groove of the drive wheel with solvent. See section 11.0 on cleaning.
4.1.1C DRIVE ARM ECCENTRIC
The drive arm eccentric ( item 34, fig 4.0 ) is used to adjust the point of contact between the
drive wheel and the jig face in relation to the throat plate ‘D’. Location holes drilled into the
base plate, item 62, ensure the eccentric does not move from the position it has been set to.
