Instructions for the
Differential Feed
Mechanism (Models
with Differential Feed)
This serger is equipped with two sets of feed dogs
under the presser foot to move the fabric through the
machine. The differential feed controls the move-
ment of both the front and the rear feed dogs. When
set at 1, the feed dogs are moving at the same speed
(ratio of 1). When the differential feed ratio is set at
less than 1, the front feed dogs move slower than the
rear feed dogs, stretching the fabric as it is sewn.

This is effective on lightweight fabric that may pucker.
When the differential feed ratio is set at greater than
1, the front feed dogs move faster than the back feed
dogs, gathering the fabric as it is sewn. This function
assists in removing the rippling when serging stretch
fabrics.

To adjust the differential feed.
(1) Locate the differential feed adjustment lever on
the left side of the machine.
(2) The normal setting is 1.0 on the differential feed
adjustment lever.
(3) To set less than 1.0, move the lever back.
(4) To set greatev than 1.0, move the lever forward.

Instruktion til modeller
med
differentialetransport
Homelocken er udstyret med 2 stk. transportører
under trykfoden for at transportere stoftet gennem
maskinen. Differentialetransportøren kontrollerer
bevægelsen af både for- og bagtransportører. Når
indstillet på 1, bevæger transportørerne sig lige
hurtigt. Når indstillet på mindre end 1, bevæger
fortransportøreren
sig
bagtransportøren, hvorved stoffet strækkes. Dette
er effektivt i tyndt stof, der let rynker. Når
differentialetransporten er større end 1, bevæger
fortransportøren sig hurtigere end bagtransportøren,
hvorved stoffet samles. Herved undgås at stoffet
flaner som f.eks. i mange tilfælde, når strækstof
overlockes.
Justering af differentialetransportøren:
(1) Regulér differentialetransportøren, som er
placeret på maskinens venstre side.
(2) Den normale indstilling er 1,0.
(3) Drej transportøren tilbage for indstilling på mindre
end 1,0.
(4) Drej transportøren frem for indstilling på mere
end 1,0.
