Title:
FELT NEEDLE EXTENDED TO AXIS DIRECTION
Document Type and Number:
Japanese Patent JPS5493171
Kind Code:
A
Abstract:
A felting needle with a barb having a fiber deflecting section and a fiber gripping section. The barb is within a triangular blade needle and has a fiber gripping section disposed in the bottom portion of the trailing edge of the barb and disposed at approximately a 70 degree undercut angle relative to the needle axis and the fiber deflecting section extends upwardly and rearwardly from the fiber gripping section at approximately 30 degrees to the needle axis. The effective depth of the gripping section is less than approximately 75% of the total barb depth. With this arrangement, owing to the barb fiber gripping edge positioned within the triangular blade and with no kick-up, the backing material fibers are protected and fiber distortion is reduced.
