1. The upper differential feed is driven by an independent stepping motor. The upper differential feed amount is adjustable, enabling flexible switching between synchronousand differential modes to achieve uniform pleating, as well as preventing misalignment for smoother sewing results.

2. Front-mounted differential connected with mechanical linkages (Patented Product).

3. Up to 15 programmable segments available for electronic upper differential.

4. Manual switching of differential feed amount and stitch length is supported simultaneously.

5. Optional telescopic bracket: compatible with various cuffs such as elastic and ribbed fabric.

6. Small throat space: 80mm left-right travel, 200mm circumference, 60mm front-rearwidth. Allows flexible operation in confined spaces for high-efficiency production.

7. Electronic stitch length, electronic back-tacking, automatic thread trimming, built-inpresser-foot lifter.

Suitable for sewing tubular sections such as garment cuffs, trouser hems and waistbands.
