DIFFERENTIAL FEED

(with differential feed machine only)

Differential feed is a system which “stretches” or

“gathers” the fabric, when amount of feed of

front feed dog in relation to the rear feed dog is

changed.

The differential feed ratio ranges from 1:0.77

1:2.0. Adjustment is made by means of the dif

ferential feed adjusting lever as shown.

Use of differential feed is very effective in over

edging stretch fabrics and fabrics cut on the bias.

(1) Gathered Overedge

(Use regular throat plate)

* Gathered overedge is most suited for shirring

sleeves, yokes, front and back bodices, skirt hems,

etc. in stretch fabrics such as knits and jersey be

fore assembling into garment.

To set the differential feed adjusting lever

* Open looper cover and loosen differential feed

adjusting lever thumb screw.

* Slide adjusting lever downward below the center

mark, as required, to gather, and tighten the

thumb screw.

Note: The setting position of the lever will differ de

pending on the material being sewn and the

amount of feed for shirring.

* When differential feed adjusting lever is set to

maximum gathering ratio, the stitch length will

automatically change to 3mm (7/64inch) if

previous setting was higher than setting “3”.

* Be sure to reset the differential feed adjusting lever

to center mark for normal overedge stitching.
