4-3  Adjusting Spreader 

a) The distance between Needle and Spreader 

  Turn  the  pulley  clockwise,  and  check  the  distance
  between the needle center and the concave part of the
  spreader  (81207)  at  the  time  when  the  spreader  is  at
  the farthest in the left. The distance must be 6.5mm
  as  shown  in 

(Figure2)

.  If  the  distance  is  larger  or

  smaller  than  6.5mm,  carry  out  necessary  adjustments
  as follows: loosen the set screw (22517) of the spreader
  lever (81238), and turn the lever  down  (direction  S')
  to  move  the  spreader  to  the  right  (direction  S  ),
  or  turn  it  up  (direction  L)  to  move  the spreader to
  the left (direction L'). Never fail to tighten the set screw
  (22517) after the adjustment. 
   

b) The clearance between Needle and Spreader 

  Turn  the  pulley  clockwise  further,  and  you  will see
  the looper moves to the right while the spreader goes
  to  the  left.  In  this  case,  note  that  the  spreader
  point passes the

 

concave part of the looper (on the far 

 

side),  as  shown  in

  (Figure  3)

.  Check  the  clearance

 

between

  t h e  co n ca ve   p art

 

o f   the  looper  an d

  the  spreader  point.  The  clearance  should

  b e

  0 to 0.1mm. 

 If the clearance does not fall within the specified range,

  loosen  the  set  screw  (318)  of  the  spreader  bearing
  (81255),

 

as  shown  in 

(Figure  4)

,  and  move  up  the

 

spreader  bearing  (in  the  direction  S)  to  make  the

  clearance  smaller  or  move  it  down  (in  the  direction
   L)

 

to make the clearance larger. 

 

Firmly tighten the set screw of the spreader bearing

 

after the adjustment. 

 

Confirm that the clearance between the needle and the

 

spreader is 0 to 0.5mm at the time when the needle is

 

coming  in  between  the  sp reader  and   the  loop

 

guide

 (81210), while turning the pulley clockwise.

   

c)

 

The center distance of the ball joint 

 

The center distance of the bal1 joint connecting the

 

spreader  lever  (81238)  and  the  spreader rocker

 

(81213AW)  is  fixed  at  105mm.  Keep  this  dimension,

 

otherwise timing of the looper and the spreader will get

 

out of order. 

Setting height of Needle Bar

 

Adjust  the  height  of  the  nedle  bar  (80617)  so  that  the
upper  part  of  the  needle  hole  coincides  with  the  looper
hole, as shown in

 (Figure 5)

 , when the looper goes to the

right and the looper hole aligns with needle center. 
For  this  adjustment,

 

loosen  the  set  screw  (BP108)  of  the

needle

 

bar vertically.

 

After the adjustment, always tighten the set screw.

   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   

4-3  スプレッダーの調整 

a) 針とスプレッダ―の距離 

<Fig.2>

 

プーリーを廻して、スプレッダー(81207)がもっとも左に
き た と き 、 針 芯 と ス プ レ ッ ダ ー の え ぐ り 部 の 距 離 は
6.5mmです。  距離の調整は次の通りです。 

スプレッダーレバー(81238)を止めているネジ(22517)

を緩めて、かるく仮締めしてください。  スプレッダーレバー
を倒す方向(S)に動かすと、スプレッダーは右方向(Sʻ)
に動きます。起こす方向(L)に動かすとスプレッダーは
左方向  (Lʻ)  に動きます。  調整が終わったらスプレッダー
レバーのネジ(22517)をしっかりと締めてください。 
 
 

b) 針とスプレッダーの間隔 

<Fig.3>

 

プーリーを廻して、ルーバーが右に動き、スプレッダーが
左に動いて、ルーバーの向こう側を通るとき、ルーバー
の向こう側のえぐり部とスプレッダーとの間隔は0〜0.1mm
です。 
間隔の調整は次の通りです。 

<Fig.4>

 

 

○ スプレッダー軸 受 (81255)のネジ(318)を緩 めて調 節

してください。 

ス プ レ ッ ダ ー 軸 受 を 上 方 向 ( S ) 動 か す と 、 間 隔 は せ

ま く な り 、 下方向( L ) に 動か す と 間隔は 広く な り ま す 。
調整が 終わ っ た ら 軸受け の ネ ジ ( 3 1 8 ) を し っ か り と 締
めてください。 
 

○ 手でプーリーを右に(時計方向に)廻して、スプレッダー

とループガイド(81210)の間に針が入るとき、針とスプ
レッダーの間隔は  0〜0.5mmです。  確認してください。 
 

c) ボールジョイントの距離 

ス プ レ ッ ダ ー レ バ ー ( 8 1 2 3 8 ) と ス プ レ ッ ダ ー 台
(81213AW)をむすぶボールジョイントとの距離は105mm
です。  この寸法は変えないでください。  この寸法が変わ
ると、ルーバーとスプレッダーのタイミングが狂います。 
 

針の高さ 

<Fig.5>

 

ルーバーが右方向に進み、ルーバーの穴が針芯上にきた
と き、 針穴の上部とル ー バ ー 穴が 一致す るよ う に調整し て

ください。 
 

調 整 は 針 棒 抱 キ ( 8 0 6 5 9 ) の ネ ジ ( B P I 0 8 ) を 緩 め て 、
針棒を上下に動かします。  調整が終わったらネジをしっかり
と締めてください。
