Self-threading needle |
摘要 |
A self-threading needle has a threading slot entering into the upper portion of the needle eye at approximately two thirds from the bottom of the eye, and has a point offset relative to the axis of elongation of the needle toward the same side of the needle from which the slot enters the eye. The slot lies in a plane substantially normal to the axis of the needle and to the wall of the needle in which the slot is formed. The needle includes a clearance above the eye and a thread accommodating groove.
