14. Adjustment of folder
WARNING :
Perform the work after turning OFF the power to prevent accidents caused by the abrupt start of the
sewing machine.
(1) Folder mounting position
Insert the slide base 3 of the folder set 2 in the center of the slide plate 1 of the right and left cylinder arms, and slide
the presser 4 in forward direction. At that time, a standard clearance of 0.8mm to 1.6mm should be secured between the
front section "A" of the presser 4 and the outlet section "B" of the upper folder 5 .
If Section "B" of the upper folder 5 is installed as closer as possible to Section "A" of the presser 4
, the result of sewing tends to be more stabilized for the material to be sewn. In such a case, however,
it is necessary to make sure not to let the upper folder 5 come in contact with the presser 4 in the
middle of sewing.

(2) Adjustment of folder mounting position
When the folder set 2 is installed, confi rm whether
1)
a standard clearance is secured between the front
section "A" of the presser 4 and the outlet section
"B" of the upper folder 5 .
If the conditions seem to be awkward in regard to the
front and rear contact between the front section "A" of
the presser 4 and the outlet section "B" of the upper
folder 5 and right and left positioning of the upper
and lower folders ( 5 and 6 ), loosen two setscrews
7 and adjust front/rear and right/left positioning of the
folder base 8 .
2)
If it is necessary to adjust the outlet at the tips of the
upper and lower folders ( 5 and 6 ), loosen two
setscrews 9 and make adjustments by moving the
tip of the upper folder 5 to the right and left.
™ To widen the outlets of the upper and lower
folders ( 5 and 6 ), move the tip of the upper
folder 5 to the left.
™ To narrow the outlets of the upper and lower
folders ( 5 and 6 ), move the tip of the upper
folder 5 to the right.
The spring !0 is fastened to the right side section of
3)
the lower folder 6 by means of the setscrew !1 .
The tip section of the lower folder 6 is devised to
have an escape recess somewhat to the right so that
an extra-heavyweight material can be duly handled.
1. According to the thickness of a material
to be sewn, adjust the upper and lower
folders ( 5 and 6 ).
In addition, for the kinds of folder sets 2 ,
there are folder sets 2 other than the
standard folder.
Refer to "14. (3) Folder types".
2. If positioning of the folder set 2 is inac-
curate, the quality of the sewn product
will be lowered.
