Description

Technical Field

[0002] Knitted fabrics are made by bending yarns into loops and interlacing them with knitting needles. The difference between knitted fabrics and woven fabrics is the different forms of yarns in the fabrics. Knitting is divided into weft knitting and warp knitting. Knitted fabrics are widely used in clothing fabrics, linings, home textiles and other products, and are loved by consumers.

[0003] During the knitting process, a winding machine equipped with a winding roller is used to wind up the formed fabric. After a certain amount of fabric is wound up, the fabric needs to be cut to replace another winding roller, and the cut fabric head is connected to the winding roller for the next winding.

[0004] However, in order not to interrupt the knitting process, the current cutting device usually cuts during the winding process. Therefore, the cut fabric still maintains relative movement with the cutter in the winding direction of the fabric, resulting in poor cutting quality and the cutting trajectory cannot be perpendicular to the length direction of the fabric, which needs to be improved.
