    • An improved tufting knife (20) has, at a distance from its cutting edge (36), a bending joint (27) from which extends one leg (26) to the cutting edge (36) and another leg (25) to a knife bar (21). The bending joint (27) ensures that the tufting knife (20) is highly flexible and that a desired contact pressure between the tufting knife (20) and the gripper (18) is maintained largely independently of the degree of lateral flexion and/or bending of the tufting knife (20). This has a strongly wear-reducing effect.
    • 一种改进的簇绒刀具(20)在与其切割刃(36)相距一定距离处具有弯曲接头(27),一个腿部(26)从其延伸到切割边缘(36),另一个腿部(25)延伸到刀具 酒吧(21)。 弯曲接头(27)确保簇绒刀具(20)是高度柔性的,并且簇绒刀(20)和夹纱器(18)之间的期望的接触压力在很大程度上独立于侧向弯曲和/或弯曲的程度而被保持 的簇绒刀(20)。 这具有强烈的减少磨损的作用。
