DIFFERENTIAL FEED APPLICATIONS
Please refer to pages 19,20 DIFFERENTIAL FEED,
Differential feed is designed to minimize puckering and
wavering.
It is also very effective for gathering.
1. Puckering
Puckering tends to occur on woven or sheer
fabrics.
To obtain pucker-free seams, set the differential
feed control dial at less than 1.
2. Wavering
Wavering tends to occur on knitted or stretchable
fabrics.
To obtain waver-free seams, set the differential
feed control dial at more than 1.
3. Gathering
Differential feed makes gathering easier on
lightweight fabric. Use it on waistlines, sleeve
heads, sleeve bottoms and ruffles, etc.
Set the differential feed control dial between 1.5
and 2 to obtain the best gathering effect for your
use.
IMPORTANT
The exact adjustment depends on the thickness and
elasticity of fabric. Even the stitch length can influence
the setting. The longer the stitches,
fabric is contracted.
Always do a test run with a piece of actual fabrics you
use and find the best settings.
