With its increased button-feeding 
speed and high-speed machine head 
capable of a maximum sewing speed 
of 1,800rpm the machine 
dramatically increases productivity.
Furthermore, its button-discharging 
mechanism and easy-to-adjust 
functions make it easy to change the 
setup when changing the buttons to 
be sewn, thereby eliminating wasted 
time at start-up.

The three different operation modes available are the 
automatic button feeding mode in which the machine 
continuously feeds the buttons in the feeder bowl, the 
non-feed mode in which the operator manually places 
the buttons in the sewing position one by one, and the 
small-lot sewing mode in which the operator sets the 
buttons in place for one garment (five or six buttons) in 
advance, upon which the buttons are automatically and 
continuously fed to the sewing position. As a result the 
machine can employed by a small-lot production system 
by selecting the appropriate operation mode.

The machine is provided with a wider 
sewing area to facilitate garment 
setting, and allows the operator to 
check the remaining quantity of 
buttons while remaining seated, 
thereby enhancing ease of operation.
Furthermore, the machine allows the 
operator to continuously sew buttons 
with pedal depressed, thereby helping 
reduce the operator’s fatigue.
