Setting The Feeding Length; A) Bottom Feed; B) Top Puller Feed - Duerkopp Adler 173 Operating Instructions Manual

3.6 Setting the feeding length

a) Bottom feed
The feed dog feeding length is
adjusted at dial 4.
b) Top puller feed
The feeding length of the puller 9 is
adjustable independent of the bottom
feed at dial 3 and can thus be
adapted to the feeding characteris-
tics of the material.
When sewing with stitch condensing
at the seam beginning and seam
end, the puller feeding length au-
tomatically adjusts to the feeding
length of the bottom feed.

Please note:
–
The puller can be swung out of the
sewing area using the hand lever, eg
for sewing with the bottom feed only.
–
To raise the puller when sewing radii
or corners, operate the lower key 5 at
the sewing head.
–
The fabric keep-off plate 8 serves
simultaneously as trimming knife for
the thread chain. (Only on machines
without thread trimmer.)
–
The puller pressure is adjustable to
the material. Loosen the screw 7 and
adjust the cylinder 6:
In direction A = higher pressure
In direction B = lower pressure.
