1. Knife assembly for mounting to a frame and cutting yarn implanted into a backing by a hollow needle comprising:

  • a flat, elongate blade having longitudinal edges and a cutting edge extending between the longitudinal edges for shearing engagement with the needle;

    a blade holder block having a passage for receiving the blade and a protrusion within the passage, the protrusion having a flat face; and

    a screw extending through the block into the passage for selectively engaging the flat blade and holding the blade flush against the flat face, and alternatively, releasing the blade, the longitudinal edges of the blade extending beyond the flat face when the blade is engaged by the screw so that the blade can flex and conform to the needle when the blade engages the needle.
