Abstract
An improved tufting knife () has, at a distance from its cutting edge (), a bending joint () from which extends one leg () to the cutting edge () and another leg () to a knife bar (). The bending joint () ensures that the tufting knife () is highly flexible and that a desired contact pressure between the tufting knife () and the gripper () is maintained largely independently of the degree of lateral flexion and/or bending of the tufting knife (). This has a strongly wear-reducing effect.
