5、机针高度调整(Needle height adjustment)
首先调整机针与针板的间隙,保证机针与针板的间隙均等,调整机针高度,机针运
行到最高点,针板到左针针尖的高度为H(图7),H参数如下表:
Adjust the gap between needle and needle plate, make sure the gap is
equal; then adjust the needle height, when the needle is in the highest
position, the distance” H” between needle plate and the left needle is like
the following sheet(Figure 7)
