摘要： A sewing machine needle has a piston for clamping the needle into a sewing machine, a needle shaft comprised of a shaft portion and an end piece with a tip, whereby the needle shaft has a needle eye between the shaft portion and the end piece for receiving a sewing thread. A conical portion connected to the piston forms a transition into the needle shaft. The end piece, between the tip and the needle eye, has a triangular radial cross-section with rounded corners, whereby the size of the triangular cross-section increases from the tip toward the needle eye, and whereby the triangular cross-section has its greatest size in the vicinity of the needle eye. The needle shaft, in the area of the needle eye, has an essentially circular cross-section, and this circular cross-section has a size that is smaller than the greatest size of the triangular cross-section.
摘要翻译：缝纫机针具有用于将针夹持到缝纫机中的活塞，由轴部和具有尖端的端部构成的针轴，由此针轴在轴部和端部件之间具有针眼，用于接收缝纫线。连接到活塞的锥形部分形成到针轴的过渡。尖端与针眼之间的末端具有带圆角的三角形横截面，由此三角形横截面的尺寸从尖端朝向针眼增加，由此三角形横截面具有其最大的尺寸在针眼附近。针眼在针眼区域具有基本圆形的横截面，该圆形横截面的尺寸小于三角形横截面的最大尺寸。
