The machine incorporates a head that is capable of
running at a normal speed of 3,600rpm and a pneumatic
knife driving device. As a result, the machine cycle
time has been shortened, thereby promising higher
productivity.
The presetting unit enables the operator to set the next
garment body to be sewn on the machine while the
current garment body is being sewn, so higher operation
rate is promised even when the operator attends several
sewing machines. (When RS types or RA types sew
garment bodies.)
The encoder detects the motion of the machine during
sewing and moves the conveyer, preventing the material
from being deformed. The stepping motor controls the
material feed amount in 0.1mm steps.
buttonholes can be consistently sewn at accurate
intervals.
