Thread end is pushed by air between the disk press-
er and the pattern at the beginning of sewing. In the
case the thread end cannot be pushed due to the lo-

blowing direction of the air to allow the thread end to
be pushed by air.

process the pattern to be sewn.

eration processing" ❸ , click ❹ ("Enter I/O") and
