4-2  ルーパーの調整 

ルーパーの調整をする前に、押エ金、針板・送り金・針ガード
を取りはずしてください。 
ルーバーの調整が容易になります。 
 
a)  針とルーパーの距離 

<Fig. 1>

 

ル ー パ ー ( 8 1 2 0 8 ) を 、 ル ー パ ー 台 ( 8 1 2 1 3 ) に 取 り 付
けます。 
針がもっとも下がったとき、ルーパーの先端と針の中心
ま で の距 離は 6 m m で す。

< F i g . 1>

距離 の 調 整は次 の

通りです。 

 
 
 
 
 

○ ルーパー台とボールジョイント(15442K)を止めている

ナット(9937)を緩めてください。 
ルーパー台とボールジョイントを S の方へ動かすと、ルー
は針 に近 づきます(Sʼ)。  L の方 へ動 かすとルーパー
は針から遠ざかります(Lʼ)。 
距離の調整が終わったらナットを緩めてください。 
 

注)距離が6mm以下では2度掛け、6mm以上では目飛び

の原因になります。 
 
 
 

b) 針とルーバーの間隔 

 

ルーバーが右に進み,  ルーバーの先端が針の後ろを通

 

過す る と き, ル ー バ ー の 先端と針の え ぐり 部との 間隔は

 

0.1mmです。ルーバー台を調整してください。 

 

 

○ ル ー バ ー 台の ネ ジ ( 9 8 ) を 緩め 、 軸方向に 動か し て 調

 

節してください。 

 

 

 

 

注) 針と ル ー バーの 間隔が な く 、 針に ル ー パ ー があ た って

 

いると、針に傷がつき、糸切れの原因になります。また,

 

離れすぎると目飛びの原田になります。 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

4-2  Adjusting of Looper 

For  convenient  access,  remove  the  presser  foot,  throa
plate and feed dog. 
 
 

a) The distance between the needle center and the looper

  Insert a looper (81208) into the looper rocker (81213).
  Turn  the  pulley  clockwise,  and  check  the  distance
  between the needle center and the looper point in the
  lowest  position  of  the  needle  bar  just  before  moving
  upwards.  The  distance  should  be  6mm  as  shown  in
 

(Figure 1) 

  If it is larger or smaller than 6mm, carry out necessary
  adjustments after loosening the nut (9937) which holds
  the  looper  rocker  (81213)  and  the  ball  joint  (15442K)
  in position, until the required distance is obtained.

○ 

Setting  the  looper  rocker  and  the  ball  joint  in  the

  directions  S  will  cause  the  looper  get  nearer  to  the
  needle  (Sʼ),  while  setting  them  in  the  direction  L  will
  make  the  looper  go  away  from  the  needle  (Lʼ).  Never
  fail to tighten the nut (9937) after the adjustment.

 

 

 

 

(Note) 
If  the  distance  between  the  needle  center  and  the
looper  point  is  shorter  than  6mm,  "double  stitching”
will  be  caused  while  the  thread  may  skip  if  it  is  larger.

 

 

b) The clearance between the needle and looper

  Turn the pulley clockwise, and adjust the looper rocker
  so  that  the  clearance  between  the  Jooper  point and
  the  needle  is  0.1mm  when  the  looper  moves  to
  the right and passes behind the needle. 

○ 

For  this  adjustment,  the  looper  rocker  can  be  moved  in

  the  axial  direction  when  the  set  screw  (98) of  the
  looper rocker is loosened. 

   

(Note) 

If  there  is  no  clearance  between  the  needle  and  the
looper,  with  the  needle  contacting  the  looper,  the
former  will  be   c aused.  Th re ad  m ay  skip if  t he

clearance is too large.
