Yarn Unwinding Option Supporting New Industrial Applications for Knitting Through Stable Yarn Feed SHIMA SEIKI's new Yarn Unwinding Option is an essential tool for supporting industrial textile applications in knitting. Normally when knitting with stiff materials such as metallic and monofilament yarns, the yarn has a tendency to kink or twist, making it practically impossible to feed smoothly into the knitting machine. To alleviate this situation, the yarn Unwinding Option is equipped with a motorized bobbin that actively unwinds yarn in the direction of the wind, providing smooth and stable yarn feed with precise control over feed amount and tension. Yarns for industrial applications can come in different packages, so the Yarn Unwinding Option supports different bobbin sizes. Replacing bobbin mounts allows various The Yarn Unwinding Option supports a Supporting a Variety of Yarns bobbin types to be mounted as wide variety of bobbin shapes and sizes, Previously impossible to knit, tape yarn well. The Yarn Unwinding Option also works in coordination with the knitting as well as different materials. Custom bobbins can also be supported.* * For custom bobbin support please consult your nearest SHIMA SEIKI representative. machine, allowing realtime (ribbon yarn), monofilament and metallic yarns, can now be knit with ease by feeding yarn into the knitting machine without twisting or kinking. For the fashion industry for example, inlay knit fabrics can be produced by weaving-in special yarn such as tape rotation speed according to the amount of yarn consumption. With the Yarn Unwinding Option, such knitted applications Supporting a Variety of Industries protective knitwear can be realized. Bobbin Mount Bobbins are mounted on motorized bobbin mounts that turn in sync with yarn consumption, providing smooth yearn feed into the knitting machine. materials previously impossible to use, the Yarn Unwinding Option opens the door to new opportunities for new applications in knitting, such as automotive, aerospace, medical, home furnishings and other industrial textile ap
