BJ-1541 Lockstitch Machine (sewing machine)
BJ-1541S(with safety mechanism)

Details:
With its larger needlebar stroke, higher presser foot lift, and newly adopted
double-tension mechanism, the machine offers excellent sewing capabilities and
responsiveness.
The alternating vertical movements of the walking foot and presser foot are
as large as 6.5mm. In addition, the ratio between alternating vertical movements
of the walking foot and presser foot remains unchanged even when the material
thickness changes. Thanks to this feature and the adoption of a new method of rectangular feed that prevents needle from fraying, the machine sews multi-layered
parts of a material with consistent stitching pitch while preventing stitch gathering.
When the thread is caught in the hook or any other sewing trouble occurs, the
safety mechanism will automatically operate to prevent the machine from being
damaged(BJ-1541S).
