A sewing machine needle includes a blade extending substantially in the needle's longitudinal direction, an eye, which passes through the needle substantially in its 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's elevational direction. At least in part of the scarf s extension along the needle, the scarf contour in a sectional plane perpendicular to the needle's longitudinal direction is substantially an arc of a circle. The circular-arc-shaped area covers a first angular portion of the needle's circumference. In this part of the scarfs extension along the needle, the radius of the substantially circular-arc-shaped contour in this first angular portion of the needle'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 elevational directions.

Embodiments of the present invention relate to hand sewing needles that have periodic markings to facilitate the creation of stitches of equal length and spacing. Because regular stitching can be difficult to produce by hand but is nevertheless necessary for a garment or other sewing product to be considered of quality, presentable, and professionally made, embodiments of the invention aid those with little sewing experience in producing regular stitching. Embodiments of the present invention also relate to methods for producing and using the disclosed hand sewing needle.

Sewing needle with double twist groove
09758911 · 2017-09-12 · ·

A sewing needle is used in a sewing machine. The sewing needle has a working portion with a needle eye and a region which tapers into a needle tip. The needle eye passes through a needle body in a transverse direction perpendicularly to a longitudinal axis of the needle body. A twist groove is recessed in a front face of the needle body relative to the outer contour of the needle body, the twist groove extending in the direction of the needle tip from the needle eye. The twist groove is formed by a thread groove. The twist groove is preferably symmetrical relative to a first longitudinal central plane spanned by the longitudinal axis and the transverse direction. The thread groove has a groove portion adjacent to the needle eye and two end portions, each having a thread groove opening, remote from the needle eye.
