5-7. Cutter operation
The cutter operating pattern can be selected from the following four patterns.
Parameter No. 06
1: Cutting during sewing
2: Cutting after sewing
3: Cutting before sewing
4: Cutting before
Cutting during sewing
Operates when the front
tack of the last buttonhole
cycle is sewn.
Operates near the front tack
when sewing is finished and
material is feeding.
Operates immediately
before the left zigzag stitch
of the last cycle is sewn.
Operates twice:
immediately before the left
zigzag stitch of the last cycle
is sewn and when the front
tack of the last cycle is
sewn.
Setting range 1:
Cutting during sewing
General sewing
Setting range 2:
Cutting after sewing
Because the needle and
cutter
positions are separated
by 2.2 mm as shown in the illustration, the distance
between the edge of the front tack and the edge of the
buttonhole cannot be set to less than 2.2 mm.
For example, if the
cutter
Y space (A) is set to 0.5 mm,
the front tack length (B) will not go below 1.7 mm. At such
times, the front tack length can be set to less than 1.7
mm when using cutting after sewing.
Once sewing is finished and material feeding has finished,
the cutter will operate.
Setting range 3:
Cutting before sewing
▪
Does not operate during the first sewing cycle. Only applies to second and subsequent cycles (during underlay sewing and
overlap sewing).
▪
This is used in cases such as when the rough edges of the material after cutting are hemmed by the buttonhole stitches.
▪
The cutter operates before the left zigzag stitch of the last cycle is sewn.
Setting range 4:
Cutting before Cutting during sewing
▪
Does not operate during the first sewing cycle. Only applies to second and subsequent cycles (during underlay sewing and
overlap sewing).
▪
This is used in cases such as when the rough edges of the material after cutting are hemmed by the buttonhole stitches.
▪
It can also be used if the rough edges of the material block the buttonhole after the left and right zigzag stitches have been
sewn.
▪
The cutter operates immediately before the left zigzag stitch of the last cycle is sewn, and it operates again when the front
tack of the last cycle is sewn.
