Machine time 1.2 sec. /
belt-loop. |
| The machine time is 1.2 seconds per belt-loop
(with 28 stitches). |
 |
The new machine head specifically
developed for belt-loop attaching machines runs at a
maximum sewing speed of 2,500rpm and is equipped with a
direct-drive system that improves start up performance
and shortens sewing time. The belt-loop feeding device
is now provided with a halfway standby capability for
subsequent belt-loops, and its faster belt-loop supply
action shortens the time required for supplying
belt-loops and helps speed up the machine time to 1.2
seconds per belt-loop (with 28
stitches). | |

 |
| With the improved consistency in belt-loop
supply action and re-try capability, the machine down time is
substantially reduced. |
 |
Belt-loops are fed out by the
conventional gear-roller feeding mechanism and also
drawn out by the new drawing mechanism on the clamp
device. Supported by these two mechanisms, the folding
fork catches “curled” or “creased” belt-loops every time
and supplies them to the head. In addition, the sensor
of the clamp device detects the presence/absence of
belt-loops. If it detects a faulty belt-loop feed, the
clamp device automatically repeats the clamping action.
Since the operator doesn't have to operate the set-back
switch, less time is lost. | |

| The machine quickly and reliably disposes
splices without any delays in cycle
time. |
 |
The machine preliminarily detects each
splice in the belt-loops and efficiently disposes them.
This means that even when the machine carries out the
splice-disposal procedure, the belt-loop feeding device
can complete its belt-loop supply action and supply the
next belt-loop well before the machine starts to sew. As
a result, the operator can perform rhythmical and
efficient sewing work with no delay in cycle time. By
detecting changes in the material thickness, the
machine's potentiometer finds splice in belt-loops and
disposes them perfectly. When changing the material
to be sewn, the change in the material thickness
recognized by the potentiometer as a splice can be
easily adjusted and programmed through the machines's
teaching function. |

|
 |
The standard machine incorporates a
1.8-fold capacity shuttle hook. The shuttle hook
improves efficiency by reducing the frequency of bobbin
thread replacement. | |

 |
The machine offers improved
flexibility. |
| The newly developed machine head comes
with a computer-controlled X-Y linear feeding system
which enables to program the number of stitches and size
of bartacking. |
 |
The number of stitches to sew a belt-loop
can be switched between; 28-, 36- and 42-stitches, and
the bartacking size can be easily changed through the
operating panel. What's more, the user can create
his/her own original sewing patterns in addition to the
standard ones using JUKI's PGM-20 programming software
developed for computer-controlled sewing
machines. | |

| Simple adjustment of the machine enables
changeover of the cutting method between cross cutting
and straight cutting. |
 |
The applicable loop width for the
cross-cutting device is increased. In this model, both
the cross-cutting device and the straight-cutting device
can now cut loop up to 20mm
width. | |
 |
The machine offers improved operability,
workability, and
maintainability. |
| An electric sliding mechanism is installed in
the front hook (near the
operator). |
 |
The newly incorporated electric sliding
mechanism is used to electrically shift the front hook
when replacing the bobbin or conducting maintenance on
nearby components in order to widen the space between
the hooks and facilitate the job. In addition, when
changing the needle gauge, the front hook can be finely
positioned in increments of 0.01mm through the operating
panel, thereby allowing the operator to easily adjust
the distance between the blade points of the two shuttle
hooks. Since the machine no longer requires any
adjustment in the hook timing (phase), needle gauge
adjustment is much simpler than ever
before. | |

| To enable computer-controlled belt-loop supply
performance, the machine has adopted a servomotor-driven
belt-loop feeding device that feeds the belt-loops to the
sewing position (i.e.,under the presser
foot). |
 |
The belt-loop feeding position is
automatically adjusted to the belt-loop width. With this
capability, the belt-loop width can be easily changed
without mechanical adjustment. In addition, when feeding
the belt-loop under the presser foot, the widthwise
position of the belt-loop can be offset through simple
manipulation of the operating
panel. | |

 |
| The widthwise position of the belt-loop can be
offset. | |

 |
| The lift of the presser foot is as high as 21mm to
ensure outstanding
workability. | |
| To improve workability in replacing
belt-loops, the belt-loops insertion opening through
which belt-loops are supplied to the feeding device is
now located on the front side of the main
unit. |
 |
The operator can visually check how the
belt-loops are fed during sewing and prevent possible
troubles in the belt-loop feed due to faulty
loop-feeding paths. | |

| The machine is equipped as standard with
an adjustable stand. |
 |
The height of the working table can be
easily adjusted to match the operator's height. The
operator can carry out sewing works in a comfortable
posture with less physical strain and
fatigue. | | | |
