9. Setting the feed dog movement
Method:
When the rising needle leaves the fabric, the feed dog moves up above the needle plate.
The raised feed dog pushes the fabric to the rear.
After completing the feed movement the feed dog drops down below the needle plate surface and the
needle penetrates the fabric.
The feed dog returns to its starting position underneath the needle plate.
Requirement:
When the rising needle point is aligned with the upper surface of the needle plate, the feed dog must be
in the position shown in fig. 15/A2.
Note:
The feed dog height and the movement of the feed dog stroke must be set correctly.
Check:
● Insert a new needle system ELx705 in “L0”.
● Set the stitch length to “4” and the standard differential stroke to “1”.
● Place a piece of paper under the presser foot (fig. 16).
● Lower the presser foot.
● Turn the handwheel in the normal direction until the needle point slightly penetrates the paper (fig.
17).
● Turn the handwheel in the opposite direction until the needle slightly penetrates the paper again.
● Carry out a visual check.
● The needle and the feed dog must move upward in accordance with fig. 15/A2.
Setting:
● Set the stitch length to “4” and the standard differential stroke to “1”.
● Loosen the fastening screw 17 on the feed eccentric 3 (fig. 18).
● Turn the feed eccentric 3 until the setting corresponds with “Check”.
● Tighten the fastening screw 17 on the feed eccentric 3.
Test:
● Carry out a visual check.
