S-7220B
Single needle direct drive needle feed lock stitcher with thread trimmer
The S-7200B's advanced-function model with needle feed.
Having no material slippage, quality finish with uniform seams is available.
Adding the needle-feed function to the S-7200B, this model has been produced. With the needle penetrating the
material, the needle and feed dog feed the material synchronously, minimizing material slippage. It is suitable
for the sewing of slippery or multiple-laid materials, and meets quality sewing with diversified materials.
Material slippage
can be prevented
The needle feed amount is
available up to 20% increase
of the lower feed amount.
Meeting designs
with long stitches
The max. stitch length of
heavy materials (-405) spec.
is 5.5 mm. It meets a wide
range of stitches such as for
elaborate-designed jeans.
Oil staining is prevented
With the adoption of the most
advanced lubrication-free
technology, the amount of the
oil lubricated to the area of the
needle bar and thread take-up
has substantially been
reduced. Collection of oil
around the jaw area is not
necessary.
The S-7220B contributes to:
- preventing material slippage, skipped stitches and stitch gathering,
for enhanced sewing quality
- producing uniform finishes unaffected by operator skill variation
