Felt needle and method of manufacturing at least one felt needle

摘要

A working portion (longitudinal direction (z) extending from the mount (10) to its working end (16) and extending along a portion of the felt needle (1) in the longitudinal direction (z) 15) a felt needle (1), which extends in the radial direction (r) and circumferential direction (φ) of the felt needle (1) and over the majority of the length of the working part (15) -Formed by a cross-sectional area (24-29) and a notch which pierces the working part (15) and extends from the outer surface of the working part (15) towards the inside of the felt needle (1) Further, the felt needle (1), which the applicant claims is novelty, comprises: at least one felt needle (1) in the radial direction (r) of the felt needle (1); With at least one bulge (7) projecting from the circumferential surface of the • the bulge (7) in the longitudinal direction of the felt needle (1) Extends only in said direction (z) along the working part (15), the bulge (7) has a volume component not belonging to the barb bead (3) of the barb (2), the barb (2) , Characterized in that it is adjacent to the longitudinal direction (z) of the felt needle (1). The applicant also claims how to make a similar felt needle (1).
