Differential feed motion
With the differential feed motion uneven seams are
avoided in knitted materials, as well as the slippage
of textile positions. Additionally, the seams cause no
wrinkles in very light materials.
Manner of operation
The machine has two sets of toothed rack feeders,
one to the front and one to the rear. Both sets move
independant of each other. Through the differential
feed motion both toothed rack sets can move them-
selves at various speeds.
The toothed transport racks move themselves in an
elliptical motion and thus transport the material:
Setting the differential feed motion
The differential feed motion is adjusted to the de-
sired direction simply by turning the adjustment
wheel for the differential feed motion u.
"N" = "Neutral Position", the toothed rack feeders
move the material forward evenly.
"G" ="Gather Position", the front toothed rack feeders
push the material forward faster than the rear
ones. Thereby, elasticated material is not ex-
tended.
"S" ="Stretch Position", the rear toothed rack feeders
push the material forward faster than the front
ones. Thereby, the front toothed rack feeders
hold the material tautly.
The differential feed motion can also be adjusted
during sewing.
