With its larger needlebar stroke, larger lift of the presser foot, and newly adopted
double-tension mechanism, the machine sews beautifully with thick threads (low
count thread) and at higher thread tensions. This allows the machine to sew a
broad range of heavy materials.
The newly developed mode of highly rigid rectangular feed guarantees outstanding
feed performance. In addition, the ratio between the alternating vertical movements
of the walking foot and presser foot remains unchanged even when the material
thickness changes.
With this feature, the machine sews multi-layered parts of the material consistently
and without stitch gathering.
The machine is equipped as standard with a mechanism to correct uneven material feed by making-micro adjustments to the bottom-feed.
