The process in this case illustrated as
follows:
(A)
(B)
(C)
Fabric Presser
Fig.

(A) A Stitch is caught by the hook
of a Needle.
(B) The stitch (with knitted fabric)
advances along with the Needle
as the latter
advances in the
arrow marked direction.
(C) Fabric Presser (Round Brush and
Fabric Gear) serves to stop
stitches (knitted fabric)
advancing along with
Needles and
to push the fabric behind the
latches of
Needles. And yet, if
there exists a
clearance between
the Fabric
Presser and Needles
(lower
surface), the
force to
hold down the knitted fabric
becomes too weak to stop
the
fabric perfectly,
followed by the
Needles which move backwards
before the
stitches have been
pushed
behind the latches of
Needles,
making it impossible to
effect
knitting.
(B) If the Fabric Presser is
positioned lower than the standard, it can not
press
up the needles, so the relative position of
needles become lower
for Yarn Feeder, and that causes
the stitches to drop or fail to knit.
(C)
In
case the edge of Fabric Presser push
up
Needles too
much.
(1) Carriage
becomes heavy in
operation.
(2)
The hooks and latches
of Needles touch
Yarn
Feeder, and
will be
bent.
