Information
Overview
It prevents uneven material feeding, meeting the highest quality sewing standards.
Examples of suitable materials and processes : Sewing requiring quality, Slippery materials, Overlapping parts, Different materials, Lengthy articles, Materials difficult to feed
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.
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.
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).
Features
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).
Max. stitch length of heavy use (-405) is 5.5 mm. It corresponds widely to stitches such as design jeans.
