良化しうる効果がある、。This I and base 11 are synchronized rotation operations and synchronized movements 1J of both feed rollers 12△, 1213 during embroidery sewing.
Accurate transfer control with JIf+, and dual feed []
- Since the base fabric K between the rollers 12A and 12B is stretched in the longitudinal direction and transferred under tension, loosening of the base fabric and local uneven expansion and contraction are avoided, and the base fabric K is transferred to both feed rollers 12A and 128.
This has the effect of increasing the embroidery stitch viscosity within a pattern and between patterns and improving reproducibility by stably and accurately leveling the embroidery pattern to 1 rlL/, reducing the deformation of the embroidery pattern and the discrepancy between the embroidery patterns by IJI.
