11-5 Feeding amount of the lace/elastic 

To adjust the feeding amount of the lace / elastic, loosen wing nut A and turn adjusting 
screw C while checking the readings on lever B.    To increase the amount, turn screw C 
clockwise.    To decrease the amount, turn screw C counterclockwise. 
Adjustable from 0.9 to 2.3mm.    Adjust according to the fabric and/or elastic to be used. 
Adjust the pressure of the elastic feed small roller (see 11-6) simultaneously. 
To increase the amount a little more, loosen two eccentric set screws from hole D. 
Turn the handwheel all the way to MAX with the wrench inserted until the handwheel 
stops and then tighten the set screws.  This increases the adjustable range from 1.4 to 
3.6mm. 

 
 
 
 
 
 
 
 
 

11-6 Pressure of the elastic feed small roller 

To adjust the pressure of small roller A, loosen 
adjusting nut B as required. 
To increase the pressure, turn clockwise. 
To decrease the pressure, turn counterclockwise.  
Adjust the pressure according to the elastic to be 
used. 

 
 
 
 

11-7 Checking the performance of the elastic feeder 

If the elastic feeder does not work well, it will not feed elastic uniformly, causing various 
kinds of trouble such as burned elastic, jammed elastic, needle breakage, uneven sewing. 
Check the following. 
1.

 

Adjust small roller A so that it can turn easily. 
If it does not, the tape cannot be fed neatly. 

2.

 

The roller link and its shaft should move smoothly. 

3.

 

The small roller spring pressure should be as light as possible, yet be sufficient to 
follow the roller speed. 

< Note > 

Decrease the pressure for stretchable lace elastic. 

Increase the pressure for non-stretchable lace elastic.
