Due to this rest period feature of the needle bar, there is no width

of throw while the needle is piercing the cloth. This prevents the crack

ing of the needle eye or curving of the needle, thereby producing

attractive

garments.

2) The sewing hook driven by bevel gear

As the sewing hook is driven by the transmission power of the bevel

gear, the

"play"

of the sewing hook is negligible

and

also as the bevel

gear is protected by a case, its durability factor is very high.
