5-4 Change of Stitch Length (Fig.13) 

The machine is adjusted to the stitch length of 8mm in our
plant before shipment. You can change the stitch length in 
the following procedure when necessary: 
Loosen  the  nut  B  of  the  feed  crank  stud  A,  and  turn  the
screw  D  on  the  Scale  C.  Turning  it  to  the  right  will  make
the  stitch  smaller  (S),  and  turning  it  to  the  left  larger  (L).
Tighten the nut B only by half and turn the pulley by hand 
to produce a length of seam to confirm whether the required
stitch  length  is  obtained  or  not.  After  the  adjustment,
tighten the nut B firmly. 
Note:  Nut  B  has  left  thread.  When  the  stitch  length is 
changed. Adjust the Needle Guard as below mentioned.

 

 
5-5 Needle Guard (Fig.14) 

Adjust  the  Needle  Guard  B  so  that  the  Looper  point  does
not  hit  the  Needle  when  the  Looper  pass  through  the
concave part of the Needle. The upper edge of the Needle
hole  must  be  even  with  the  lower  furface  of  the  Needle
Guard B when the Needle A is in the lowest position in its
travel. 
To adjust, loosen the Screw C and move the Needle Guard
B  in  the  vertical  direction.  Be  careful  that  the  Needle  A
slightly  touch  the  Needle  Guard  B,  so  that  the  clearance
between  A  and  B  is  0  to  0.1mm.  After  the  adjustment,
tighten the Screw C firmly.

 

 
5-6 Presser Foot (Fig.5 See page 5) 
a) Presser Bar Height (Fig.5) 

Make sure the height of the Presser Bar is set correctly if
the Needle Bar Nut C will not contact the Presser Foot
and if it is possible to remove the Presser Foot D, when
the  Presser  Foot  Lever  is  pushed  down  and  the  Needle
Bar is at the highest position in its travel. 
Loosen  the  Screw  E  and  adjust  the  position  of  the
Presser Bar Connection. Please check the distance 8mm
between the lower surface of the Presser Bar Connection
and the Machine Frame.

 

 

b) Presser Foot Pressure 

Adjust the pressure of the Presser Foot so that the fabric
is fed uniformly. 
Turn the Presser Bar Spring Regulator F to the right to
increase  the  pressure,  and  to  the  left  to  decrease.  Too 
much  pressure  will  cause  thread  break,  but  too  weak
pressure will cause the unsuccessful chaining on the end
of the fabric.

/調整 

5-4  縫い目幅の調整(Fig.13) 

この製袋用ミシンは縫い目幅 8mm に調整し出荷していま
す。縫い目幅を変更する時は、次の順序で調整してくださ
い。 

 

送リ調節軸 A のナット B を緩めてください。 
注)ナット B は左ネジです。回す方向に注意してください。

 

目盛板 C の上にあるネジ D を回します。 
ネジ D を右に廻すと縫い目幅は小さくなり(S)、左に廻すと
縫い目幅は大きくなります(L)。 

 

ナット B を仮締めしてテスト縫いをしてください。テスト袋の
縫い目を見て希望の縫い目幅になっているかどうか確認
してください。 
確認ができましたらナット B をしっかり締め付けてください。
注)ナット B は左ネジです。縫い目幅を変更する時は必ず
針ガードも調整してください。(下記ご参照)

 

 

5-5  針ガードの調整  (Fig14) 

針ガード B は、ルーパーが針のえぐり部の横を進む時、ルー
パーの先端が針にぶつからないように調整します。(0〜
0.1mm) 
針がもっとも下がった時、針の穴の上面と針ガード B の下面
が一致するようネジ C を緩めて針ガードは針にかるく接触す
るように注意してください。調整が終わったら、ネジ C をしっ
かりと締め付けてください。 
 
 
 

5-6  押エ金の調整(5 ページ Fig.5) 
a) 高さ調整 

押エ揚ゲレバーをプーリーの方向に一杯押し下げて押エ
棒を上げ、針棒をもっとも上げた位置にした時、針棒ナッ
トが押エ金にあたらず、押エ金の取り外しができる状態が
適正です。 
押エ棒抱キの下面とミシン本体の間隔は 8mm です。 
押エ棒抱キのネジ E を緩めて、押エ棒抱キの位置を調整
してください。 
 

 
 

b) 押エ圧の調整 

袋が一定に送リ出されるように押エ金の押エ圧を調整しま
す。 
押エ棒スプリング調節 F を右に廻すと押エ圧が強くなり、
左に廻すと弱くなります。 
押エ圧が強すぎると糸切れの原因になります。しかし弱す
ぎると空縫いが出なくなります。
