5-7 Thread Tension (Fig.15) 

The  Thread  Tension,  the  Needle  Thread  take-up,  the 
Thread  Eyelet  are  the  important  parts  to  get  the  uniform
stitches.  Please  see  and  check  the  stitch  form  and  stitch
tension and then, adjust the parts.

 

 

a) The  Tension  on  the  needle  thread  should  be  only

sufficient  to  produce  uniform  stitches  on  the  under
surface  of  the  fabric.  The  Tension  on  the  looper  thread
should be just sufficient to steady the thread. 
 

b) Needle Thread Tension and Eyelet Guide 

Turn the pulley in the operating direction until the needle
bar  reaches  its  lowest  position.  Set  the  needle  thread
take-up  wire  B  so  that  the  distance  between  its  thread
contact surface and the hole of the needle thread take-up 
hole C is 5mm. 
 

 

Check the size of the loop formed as the needle goes up,
and raise the needle thread take-up wire B if the loop is
smaller, and lower it when the loop is large. 

 

In case DKN-3, Set the Eyelet guide so that the distance
between  the  center  of  the  screw  E  and  the  top  of  the
thread eyelet is 22mm.

 

The  tightening  torque  of  major  parts  is  indicated  on  the
catalog. Unless otherwise specified, all the parts with a slot
or  eccentrics  should  be  tightened  with  22  to  24kg/cm.  All
other nuts, screws and bolts without the torque requirement
specifications should be tightened as firmly as possible. 

5. Adjustment

/調整 

5-7  糸調子関係(Fig.15) 

糸調子、上糸調節、糸ガイドはきれいな縫い目をつくる重要
な部品です。糸締まり、縫い目を見て調整してください。 
 
a) 糸調子 

上糸の糸調子は、袋の裏側の表面にきれいな縫い目が
出来るように調整します。下糸の糸調子はしっかりした縫
い目をつくるように調整します。 
 

b) 上糸調節と上糸ガイド(Fig.15-a, Fig.15-b) 

針棒をもっとも下げた位置にします。上糸調節 B の上面と
上糸天秤の穴 C の間隔を 5mm になるよう上糸調節の位
置を調整してください。 
 

 

プーリーを廻して、針がもっとも下の位置から上がる時の、
糸のループの形状をみて、ループが小さい時は、上糸調
節 B をあげます。逆にループが大きい場合は下げてくださ
い。 

 

DKN-3 の場合は、上糸ガイド D は取り付けネジ E の中心
から、上糸が通る穴までの距離が 22mm になるように調節
してください。(Fig.15-c)

6. Cautions when using the machine

/使用上の注意事項 

主要部分の締め付けトルクはカタログ上で指示してありま
す。全ての長穴の部品、偏心している部品は特に指示され
ていない限り、22〜24kg/cm で締め付けてください。又、そ
の他のトルク仕様のない全てのナット、ネジ、ボルト等につい
ては出来るだけきつく締め付けてください。
