12.2 Aligning the folder as to the middle of the pocket opening
Caution: Danger of injury !
Switch off the main switch.
Align the folder as to the middle of the pocket opening only with the
main switch turned off.
Standard checking
If properly fastened, the folder 5 can be aligned as to the middle of the
pocket opening from the measuring line 1.
The dimension x can be calculated according to the width of the folder
sole 3. With the help of this dimension the folder can be aligned as to
the middle of the pocket opening 2 as well as in parallel position to the
measuring line 1.
–
Deduct the piping width a and half the needle distance NA from the
dimension 125 mm.
Example from the sketch:
125 mm - a - 1/2 x NA
= x
125 mm - 5 mm - 1/2 x 12 mm = 114 mm
–
Check the distance between folder sole and measuring line 1.
Correction of parallel position
–
Loosen screw 6 slightly.
–
Align the folder sole in parallel position to the measuring line 1 with
the help of a measuring rule.
–
Tighten screw 6.
–
Loosen screw 7.
–
Set the distance x (in the example x = 114 mm) between measuring
line 1 and the left edge of the folder sole 3.
–
Turn folder 5 on finger 4 in such a way that the folder sole slightly
ascends by 0.5 mm on 100 mm length starting from the sewing
area. This facilitates the material feed.
–
Tighten screw 7.
