High-speed, Computer-controlled Buttonholing Indexer
ACF-172-1790
● High-performance indexer mechanism
A stepping motor controls material feed amounts in
increments of 0.1mm to feed materials with both
consistency and accuracy. The machine is able to sew 1 to
20 buttonholes and stores 20 different stitching patterns in
its memory. When combined with a preset device and a
garment-body stacker, the machine produces buttonholes
with higher efficiency.
● The machine comes with an LBH-1790, which has been
developed with the central focus on functions and
performance.
The maximum sewing speed has been increased to
4,200rpm. The adoption of a direct-drive motor helps to
increase accuracy of the machine's performance with
respect to startup at the beginning of sewing and stopping
at the end of sewing, thereby contributing to increased
productivity. (It should be noted that productivity depends
on sewing conditions.)
With JUKI's unique active tension (electronic thread tension
control mechanism), it is possible to change over the
needle thread tension at parallel portions and bartacking
portions of a buttonhole with reliability to finish with a
beautifully stitched shape. In addition, a new-model thread
trimming mechanism shortens the thread remaining at the
end of a seam after thread trimming, thereby saving thread
nipping. Furthermore, fastening stitches at the end of
sewing prevent a seam from loosening.
● Daily Productivity (Working hour : 8 hours/day)
One operator works two machines : 2,150 2,420 pieces
One operator works three machines : 3,220 3,680 pieces
