工业用机针
刀针 - 皮革材料专用机针
For the sewing of leather and similar materials (thick card, sheet rubber, synthetic shaft materials etc.) the needles used have points with cutting edges. Because of their properties of incision, needles with cutting points penetrate the material more easily and cause less needle temperature than round points. Materials with a homogenous structure are weakened by cutting but their general strength does not deteriorate noticeably if the correct point shape is selected and the correct stitch length is maintained when sewing.
