Standard Adjustment

1) Adjustment of top fancy cam

1. While the top decoration cam

is moved leftward, the decoration thread passes through the thread

slider section of the top decoration looper and is caught by the thread hanger section.

The standard position is secured when the fancy thread is released from the crest point of the top fancy

looper

after the thread has been hooked on the thread hanger section.

2. The standard height (spun thread) of the top fancy thread path

is 2.4mm above the top face of the cam

thread path mounting base

(Caution) The amount of thread drawing out may change according to the type of the thread used.

The adjusting height of the top fancy thread path also changes.

(Caution) The cam position should be advanced when a wooly thread (high elongation) is used.

Since the wooly thread is stretchy, it is necessary to increase the amount of thread draw-out.

Cam’s crest point

2) Adjustment of bobbin thread cam

1. The standard size is 2mm for the position where the bobbin thread (spun thread) is released from the

releasing point of the bobbin thread cam

. This size is measured from the side face of the contact screw

in the cam groove position to the upper end of the cam groove.
