Adjusting Top Thread Tension; Bobbin Tension - Singer Stylist 7258 Instruction Manual

调整上线张力

ADJUSTING TOP THREAD TENSION

把机器的上线张力调节器设置在"AUTO（自动） "档，
可以完成 90% 的缝纫操作。
90% of your sewing will be done with the tension control dial (on
top of the machine) set at "AUTO" .
友情提示：调节数值大小，可改善缝纫效果。
Helpful Hint: A slight adjustment to a higher number or a
lower number may improve sewing appearance.
直线线迹
STRAIGHT STITCHING
美观的线迹在很大程度上取决于上线和下线的平稳线张
力。当缝纫布料时，上线和下线能稳定地固定在布料的
中间层，那么就能保持平稳的线张力。
如果发现缝纫线迹不规则，那么需要调整线张力。
进行任何调整时需要放下压脚。通常只有在缝纫直线线
迹时才需要平稳的线张力（确认上线和下线的线迹） 。
The correct appearance of your stitching is largely determined by
the balanced tension of both top and bobbin threads. The tension is
well balanced when these two threads 'lock' in the middle of layers
of the fabric you are sewing.
If, when you start to sew, you find that the stitching is irregular,
you will need to adjust the tension control.
Make any adjustments with presser foot 'down'.
A balanced tension (identical stitches both top and bottom) is
usually only desirable for straight stitch sewing.
曲折缝和装饰线迹
ZIG ZAG and DECORATIVE SEWING
进行曲折缝和装饰缝时， 上线张力一般小于直线缝纫时。
当上线出现在布料的底部时， 总是可以得到美观的线迹，
几乎没有褶皱。
For zigzag sewing and decorative stitch functions, thread ten-sion
should be less than for straight stitch sewing.
You will always obtain a nicer stitch and less puckering when the
upper thread appears on the bottom side of your fabric.
梭芯张力

BOBBIN TENSION

梭芯张力在机器出厂时就已经校准，一般情况下操作者
不需要再作调整。
The bobbin tension has been correctly set at the factory, so you do
not need to adjust it.
