Most subclasses:
- W122 – general seaming/bottom hemming.
- W162 – general seaming/bottom hemming for heavy materials.
- W222 – for tape binding.
- W512 – elastic/lace attaching.
- W522 – elastic/lace attaching with right fabric trimmer.
- U712 – tape attaching for neck sewing (two needles, two loopers).
- W922 – 4 -needle flat seaming (flatlock sewing imitation).
FFT – top and bottom differential feeding function. FFT machines are designed for the most demanding sewing materials, multiple layers of materials, etc. slippery. The effective feeding stoke is bigger and fabric feeding is more stabile.
All machines F007K and F007KD are available with energy efficient servo motors. Subclass Most of F007KD series are equipped with automatic thread trimmer and presser foot lifting.
Dual Thread Take-up Mechanism. The brand new design of dual thread take-up lever thread tension combination is ideal for both heavy and light fabric. Sewing applicable range is wider and the applicability is higher.
