Box Feed - Industrial Sewing Machine Technology
In order to provide beautiful seams and outstanding feed performance, Juki adopted box feed system. The conventional feed mechanism is oval motion. This eliminates material shrinking and shifting. The accurate feeding system provides superior stitch quality for a variety of light to heavy weight fabrics.
- Capability to sew from light to heavy weight materials
- No Fabric shrinkage even sewing on extra light weight materials
- Thick handles can be sewn with ease
From what I read by users of this machine it is similar to Pfaff's IDT. Feeds the fabric evenly and doesn't pucker up. Some say they don't need to use the walking foot attachment because of the box feed.
