(with wiper unit)
●
The machine has 55 different stitching patterns as standard.
sewing shapes, the buttonhole intervals and number of stitches can also be
changed on the operation panel.
different button specifications to increase its range of applicability, reduce costs
associated with changes in specifications, and save the operator from having to
adapt the machine to different specifications.
●
The machine performs thread trimming at the optimal position by correcting the
button position with respect to the needle entry of the last stitch.
the thread remaining on the material after thread trimming to approx. 3.5mm.
●
The machine comes as standard with the solenoid-operated, thread-tension-
changeover "thread-fray-prevention function. "
to use a long needle (TQ 7), the "thread-fray-prevention function" can be used
for sewing shank buttons.

● 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.
machine allows the operator to continuously sew buttons with pedal depressed,
thereby helping reduce the operator's fatigue.
