Productivity is increased with a maximum knitting speed of 1.4 meters per second, combined with the R2CARRIAGE® System that improves efficiency in each course through quicker carriage returns. It also carries over proven SHIMA SEIKI technology such as our
renowned Digital Stitch Control System (DSCS®), spring-loaded Full-Sinker System, Stitch Presser, Takedown Comb and Yarn Gripper and Cutter which is now equipped with a new lint remover for reduced maintenance. Equipped with the 21-intarsia carrier option, SIR® allows great freedom in knitting intarsia garments, aided by tremendously capable design system software.
Production lead times can be dramatically reduced using the Automatic Intarsia Carrier Setting software featured on our SDS®-ONE APEX3 apparel design workstation. Made-in-Japan quality, reliability, productivity, user friendliness and cost-performance combine to satisfy the high expectations of the world’s fashion industry.
