3.  침이송량의  조정  /  Needke  feed  amount

 

 ★ 침이송량을  표준이송량에  대해서 1.2배(20%)  크게  할수가  있습니다.

         미끌리기 쉬운  옷감이나  후물용의 옷감봉제를 할  때  조정해주십시오.

         표준침이송량의  경우는  단나사①이  수평이송완②의  타원형구멍의 

         수평이송축  측에 부착되어  있습니다.  침이송량을  크게할  때는  너트③을 

         풀고,  침이송연간④을  이동시켜주십시오.

    ★  The  needle  feed amount  can  20%  larger  than the  standard needle

         feed  amount.  Increase the  needle  feed amount  when sewing

         slippery  or  thick  materials. 

         For  standard feed,  the stud  screw  ①  in  the  slot  of the  feed  rocker

         arm②  is  set  to  the side close  to the  feed  rocker shaft.

         To  increase  the  needle feed  amount,  loosen  the nut  ③  and 

         move the  needle  feed connecting  rod  ④  to the  opposite  side  of  the 

         feed  rocker arm  ②  slot.

1. 고정나사①을  풀어주십시오.

2. 미싱풀리를 돌리고,  침봉이  최하위치에서  5mm상승했을  때  사절솔레노이드②를  누릅니다.

3. 사절솔레노이드②를 누른  상태에서  사절캠③의  홈부를  고로축④에  삽입하고  사절캠③ 단면과  고로축④

     단면의 틈을  0.6~0.8mm로  한 후,  사절캠③의  홈부를  고로축④에  접하도록  하고,  고정나사①을  체결해주십시오.

4. 사절솔레노이드②를  복귀했을  때  사절캠③  단면과  고로축④  단면의  틈이  약0.5mm가  되어  있는  것을  확인해주십

시오.

※  고정나사①은  약40Kg/㎠로  체결해주십시오. 

1. Loosen the  screw  ①  and  turn  the machine pulley  until  the needle  bar is raised  5  mm  above  its  lowest

     position,  then  depress  the  thread trimming  solenoid ②.

2.  With the  thread  trimming solenoid ②  depressed, fit  the indentation of the  thread  trimming clutch ③  over  the

    roller  shaft  ④.

3. When  the  space  between  the side faces of  the  thread  trimming  clutch  ③  and  the  roller  shaft  ④  is 

     0.6~0.8mm,  tighten  the screw  ① so  that  the indentation of  the thread  trimming  clutch ③  contacts  the

     roller  shaft ④.

4. Check  that  the  space  between the  side  faces  of  the  thread  trimming  clutch  ③ and  the  roller shaft  ④ 

     is  0.5mm when the  thread trimming solenoid  ①  is  returned  to its original position.

※  Tighten  the  screw  ①  with  a  torque  of approx.  40  Kg/㎠
