ADJUSTING THE BITE AND CUTTING SPACE
B i t e
-
is the distance between the two points of entry of the
needle into the fabric as it descends to make the stitch
- character of material determines the width of bite
Cutting space - it is space between the left and right bank
of stitches into which the cutting knife descends to
cut the material
The ideal width of this space depends upon neatness
required and character of material
Thin fabrics require but little - thick goods more - the
range is from 0” to 3/64”.
To adjust the width of bite - loosen nut
n
and move the
link
o
up or down in direction of arrow to suit.
Moving this link
o
upward will narrow the width of bite
- downward will widen it.
To adjust the width of cutting space - loosen the screw
q
and with pin wrench bodily move to screw head
q
to
suit.
Note:
On cut before machines this adjustment should be made
so that the inside stroke of the needle will be in center of
the buttonhole slit.
TO ADJUST THE CLAMP SPREAD
Various kinds of material require more or less
spreading of goods between the clamps. To vary
this spread or to equalize it - use adjustment
shown in Figure 4 and below.
Loosen screw
s
on each side of the machine and
move adjusting slides inward for more spread -
and outward for less.
Note:
Be sure that one side is not spreading more than the other.
