NLI DS-9 Series Manual Download Page 9

The  looper  movement  of  this  machine  has  been  properly
adjusted  before  shipment  from  the  factory,  but  if  it  needs
re-adjustment  when  it  is  disassembled  for  repair  or  etc,
prcceed as follows. 

DS-9 型ミシンは、弊社で適正に調整をして、出荷しています
が、部品交換などで調整が必要になりましたら、次の調整方
法を参照に、調整してください。 

1. Thread Tension (Figure 3) 

 
Thread  tension  is  most  important  for  successful  sewing,
Maladjustment results in thread break, skipping stitches and
break of bag. 
Proper thread tension may slightly vary with the type of bag
and  thread.  The  norm  is  given  below.  Thread  tension
regulators  are  mounted  so  that  the  tension  is  uniform  for
stitch length. To adjust the tightness of seam, adjust  ①,③
in Figure 3. 

1) 

Heavy material (jute,etc.) 

Thread tension regulators  ①  should be loosened slightly
(turn  the  adjust  nut  counterclockwise),  Needle  thread
controller  ②  after loosening set screw. 

2) 

Light material 

Tighten thread tension regulators  ①  (turn the adjust nut
clockwise). 

3) 

Needle thread 

At  the  shipment,  the  needle  thread  controller  ② for 
Creped Paper Tape is adjusted a little downward. In case 
of using sewing machine without Creped Paper Tape, the
needle  thread  controller  ②   should  be  re-adjusted 
upward. 
The  feed  rate  of  thread  must  be  adjusted  according  to
stitch  length  and  thickness  of  bag.  If  thread  tension
regulator  adjustment  is  not  sufficient  for  obtaining  the
required thread tightness, use needle thread controller  ②
by moving it up or down as necessary, after loosening set
screw. Thread is tighter by moving it up (in the direction
of the arrow), and is looser by moving it down. Tighten the 
set screw after adjustment. 

4) 

Looper thread 

Looper thread tension regulator  ③  should be adjusted in
accordance with adjustment of the needle thread tension
regulator. Adjust it so that the looper thread will not sag.If
looper thread tension is too much, the needle thread may
break. 

1. 糸調子の調整  (Fig.3 参照) 

 
糸調子は袋を縫う上で最も重要な部分です。注意してくださ
い。糸調子の調整を間違えると糸切れ・目飛び・袋の破断な
どの原因となります。 
糸調子<Fig.3-①③>の調整は袋と糸の種類で多少の違い
がありますが、原則として次の通りに調整してください。 

1) 

厚物袋(麻袋など)使用の調整 

糸調子①の糸の押さえかたを比較的ゆるくしてください。
糸調子スプリングを指で押し下げてから糸調子ナットを左
へ(時計と逆方向に)回してください。糸調子スプリングが
ナットの裏側の溝に入ってナットの回転が固定されるまで
まわします。確認してください。 
(また上糸調節②はネジを緩めてやや下げます) 

2) 

薄物袋使用の調整 

糸調子①の糸の押さえかたを強くしてください。糸調子ナ
ットを右に回してください。 
(また上糸調節②はネジを緩めてやや上げてください) 

3) 

上糸調節の調整 

工場出荷時はクレープテープ用に上糸調節②を少し下
げて調整しています。テープを使用しない時は上糸調節
を上げて再調整してください。 
縫い目幅、袋の厚さの違いで糸調子だけでは糸締まりが
悪いときは上糸調節②を上下させ調節します。上糸調節
を矢印方向に上げると糸は締まり、逆の方向に動かすと
糸は緩みます。適正な位置でネジ(11/64S40009)で上糸
調節を固定してください。 

4) 

下糸の調整 

下糸の糸調子③の調整は上糸の糸調子に合わせます。
下糸がたるまないように調整してください。下糸の糸
調子の押さえ方が強いと、上糸の糸切れの原因となり
ます。注意してください。

 

2. Presser Foot Pressure 

 
Presser  foot  pressure  must  be  adjusted  according  to  the
material  of  bag  and  thickness.  Check  the  reverse  side  of
seams.  The  pressure  is  too  strong  if  seams  show  a  sign  of
scratches  by  feed  dog  teeth,  or  the  actual  stitch  length  is
shorter than the preset feed rate of feed dog teeth. In this
case,  unscrew  plate  spring  adjust  screw(102171),Figure  4,
after loosening nut (5/16N24301). Be sure to tighten the nut
after the adjustment. If the pressure is too weak, seams do
not form a straight line, or the stitch length is irregular. In
this case, increase the pressure by screwing the plate spring
adjust screw.  Decrease the pressure when closing jute and
other  heavy  bag  material,  and  increase  it  when  closing  PP
woven  cloth  and  other  light  bag  material.  Your  machine  is
adjusted for 3-ply kraft paper bags at the factory.   
 

2. 押エ金の調整 

 
押エ金の押エ圧は袋の材質や厚さの違いで調節してくださ
い。縫った袋の裏側の縫い目を見てください。送リ金によっ
て傷がつき、また縫い目幅が送リ量より小さいときは押エ圧
が強すぎます。板バネ調節ネジ(102171)を緩めて調節して
下さい。そのあとナット(5/16N24301)をしっかり締めてくださ
い。押エ圧が弱いと縫い目が直線に縫えず、また縫い目幅
も不揃いになります。前述の調整と逆に調節ネジを締めてく
ださい。麻袋など厚物の袋を縫うときは押エ圧を弱くしてくだ
さい。PP クロス袋など薄物の袋を縫うときは押エ圧を強めに
してください。工場出荷のときはクラフト3層の紙袋に合わせ
た調整をしています。
