3) Leftmost point of top fancy looper
While the top fancy looper
is moved leftward, the fancy thread passes through the slider section and the
position of being hooked on the thread hanger section is located at the extreme left. When the tip of the top
fancy looper
reaches the extreme left point, the standard size of 2.0mm from the left middle side face of
the presser main body is secured.
4) Clearance developed at the time of crossing between the fancy thread carrier and the tip of the top fancy looper
When the fancy thread carrier
is retreated, it is crossed by the tip of the top fancy looper
. The standard
clearance is 0.4mm when both items make the closest approach.
5) Rightmost point of top fancy looper
The needle lowers when the tip of the top fancy looper
reaches the rightmost point and then moves to the
left.
The standard positioning is that the fancy thread is not caught by the retainer needle at that time.
6) Height of top fancy looper
The height of the top fancy looper
is kept
unchanged.
