About the Product

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.

Main Features

• Prevents uneven material feeding Movement is transmitted directly from the horizontal feed shaft, so that the needle feed and lower feed are perfectly synchronized, preventing uneven material feeding on diversified materials. The needle feed amount is available is available up to 20% increase of the lower feed amount.
• Needle Breakage Prevention Function When reverse stitching is carried with the actuator switch, needle breakage may occur. With the 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).
