Confirmation :
1. Perform the thread trimming sewing in
practice.
2. Confirm that the condensation amount (pitch
before one stitch of thread trimming) is proper
( * ) in accordance with the sewing conditions.
* The length of thread remaining on the
cloth side is shortened by decreasing the
condensation amount. When the amount is
excessively decreased, however, the cloth is
tore by the seams and the stitch skips. As a
result, thread trimming trouble occurs.
In addition, when the amount is excessively
increased, thread-handling trouble occurs. As
a result, thread trimming trouble occurs.
Condensation amount of 1.5 to 2 mm is
recommended.
