摘要:A sewing machine needle includes a blade extending substantially in theneedle's longitudinal direction, an eye, which passes through the needle substantially inits elevational direction, and a scarf, which extends along the needle behind the eye.Compared with the contour of the blade, the scarf contour is recessed in the needle'selevational direction. At least in part of the scarf s extension along the needle, the scarfcontour in a sectional plane perpendicular to the needle's longitudinal direction issubstantially an arc of a circle. The circular-arc-shaped area covers a first angular portionof the needle's circumference. In this part of the scarfs extension along the needle, theradius of the substantially circular-arc-shaped contour in this first angular portion of theneedle's circumference is between 35% and 100% of the needle's maximum lateral reach.The needle's lateral direction is perpendicular to its longitudinal and elevationaldirections.
