Newlong Industrial Japan 29105AK Looper Driving lever Crank Assembly for Machine type Newlong Industrial DKN3BP. How does it work? The crank converts the rotary motion of the main drive shaft into the oscillating motion required by the looper. This oscillation allows the looper to loop around the needle and grab the thread, creating the chain stitch.
The crank is made from high-quality metal, such as steel, for durability and strength. It consists of a main body with a bearing that houses the crank pin. The crank pin connects to the looper arm, and its rotation moves the arm back and forth.
A properly functioning Looper Driving Lever Crank is essential for maintaining consistent stitch quality and machine performance. Worn or damaged cranks can lead to skipped stitches, uneven stitching, and machine malfunction.
Regular maintenance and inspection of the crank are crucial to ensure its longevity and prevent machine problems.
Replacing a worn or damaged crank is a relatively simple process, but it’s recommended to consult the machine’s manual or a qualified technician for assistance.
