KRAFFT KF-1510J
1-NEEDLE LOCKSTITCH MACHINE WITH TRIPLE FEED
The KRAFFT KF-1510J is a 1-needle lockstitch machine with triple feed (feed dog, walking foot, and needle feed), designed for sewing heavy materials such as leather, furniture and automotive upholstery, technical textiles, and other multi-layer fabrics.
The machine is equipped with a safety clutch mechanism that protects the needle and hook from damage in case of thread jams or operator errors. Its large-capacity horizontal rotary hook allows for more thread per bobbin – an essential feature when working with heavy threads and long seams.
A graduated dial on the machine head enables precise adjustment of the inner presser foot alternating height, optimizing material handling based on thickness. The KF-1510J uses wick lubrication with automatic hook lubrication for increased durability and long-term reliability.
