There are 9 types of cams from No.1 to No.9 (9 types of standard patterns).
Various kinds of decorative stitches can be produced by a combination of 2 cams.
The inside cam moves the upper spreader. The outside cam moves the lower two
spreaders and crosses spreader threads.
< Note >
Raising needle thread guard A increases the size of the needle
thread loop. Lowering needle thread guard A decreases the size
of the needle thread loop.
