Abstract

1,136,020. Making sewing needles. ZENTRALE ENTWICKLUNG-KONSTRUKTION FUR EISEN, BLECH, METALLWAREN VEB. 19 May, 1966, No. 22263/66. Heading B3A. [Also in Division D1] A method of making the eye portions of sewing machine needles comprises press-forming opposed thread grooves in the needle with further depressions 12, 13 beyond the bottoms of the grooves to provide an eye web 11 between the depressions, further press-forming the eye web to reduce its thickness. and punching out the eye web, whereby an eye is provided which requires no manual grinding or polishing. The walls 9 of the eye extend obliquely towards the long thread groove and the median lines 10 of the cross-pieces are off-set. The material displaced during the press-forming operations forms lateral burrs (15) which are removed in a punching operation.
