New Thread Take Up for W - and WT - series
The new tension less thread take up was introduced to improve sewing
conditions on light weight and sensitive fabric. The needle plate has
a thickness of 3,3, mm, needle thread take up and looper thread take up
were improved to minimise thread tension and to avoid or reduce the bridge
effect.
To differentiate from standard production following Y-numbers were introduced:
| W500 - series |
Y1400 |
| W600 - series |
Y1401 |
| WT - series |
Y1402 |
Please also refer to TC-D0022 on this subject, informing about the changes
in parts. New style thread take - up and thread guides are used.
The introduction of the new subclasses is delayed.
