S-7220C Basic functions
・The needle feed mechanism prevents uneven material feeding
・Clean sewing with no oil staining
・Smooth sewing with direct drive system
The needle feed lock stitcher is suitable for the sewing of slippery or multiple layers of material.
It prevents uneven material feeding, meeting the highest quality sewing standards.
The needle feed mechanism prevents uneven material feeding.
Movement is transmitted directly from the horizontal feed shaft, so that needle feed and lower feed are perfectly synchronized, preventing uneven material feeding
for diversified materials.
The needle feed amount is available up to 20% increase of the lower feed amount.
Needle Breakage Prevention Function
When reverse stitching is carried out with the actuator switch, needle breakage may occur. With thorough analysis of its cause, the function preventing the needle breakage has been introduced.
Meets designs with long stitches
When the needle penetration resistance is increased in extra-thick overlapping part sewing, the needle penetration force is automatically increased by the vibration control (intermittent impact).
Corresponds to the design of a coarse stitch
Max. stitch length of heavy use (-405) is 5.5 mm. It corresponds widely to stitches such as design jeans.
Examples of suitable materials and processes
Sewing requiring quality(Placket stitching of polo shirt), Slippery materials (Sportswear, rain wear), Overlapping parts(Stitching of jeans), Different materials(Waist lining sewing of skirt and slacks), Lengthy articles(Curtain, quilt cover), Materials difficult to feed(Coat etc. Quilting/fleece)
