Appropriate Acti-Feed Settings
Finding the perfect settings or limits for your acti-feed is not always necessary, but it can improve sew quality
and machine performance.
Sew quality and thread breaks are indicators of appropriate or inappropriate thread feed. Those symptoms
are listed in the sections below.
Acti-Feed Minimum Value is Adequate When...
The minimum does not need to be adjusted when:
Satin and fill stitches - There is no looping or pulling on the top of a sew-out when sewing satin and fill
·
stitches.
Satin stitches - On the back side of the sew-out, you can see approximately ⅓ of the bobbin showing
·
in the middle of columns and the top color for the remainder around the sides.
· Fill Stitches - On the back of the sew-out, the top thread is even along the outer edge of the shape.
Increase Acti-Feed Minimum Value When...
When too little thread is being fed into the design, you need to increase the material thickness value. If you
experience any of the following problems, you may need to perform this adjustment.
Satin stitches - You are encountering thread breaks and can see bobbin thread on the top of the
·
design.
Satin stitches - Too much bobbin is showing on the back of the design.
·
Fill stitches - You can see bobbin thread on the top of the design.
·
Fill stitches - There is insufficient top thread showing on the back of the design.
·
Registration Loss - If designs are not lining up when sewn and the cause is the thread being pulled
·
way too tight, increasing the Material Thickness may help. Using a stable backing will also help.
Decrease Minimum Acti-Feed Value When...
When too much thread is fed into the design, you must decrease the material thickness value. If you
experience any of the following problems, you may need to perform this adjustment.
Satin stitches - The stitches in the design are looping.
