Abstract

1286282 Making needles; forging ORGAN HARI KK 13 Oct 1969 50120/69 Headings B3A and B3H [Also in Division D1] Sewing machine needles are made from continuous wire 1 by reducing the cross-sectional area of a segment 2 to form an elongated stem portion, and thereafter rolling at least the stem to a cross-section of greater length than breadth with flattened sides 4. A reference plane 3 is formed at right-angles to the major axis of the stem cross-section. The needle blank is placed between die blocks 10, 11, which move in a direction at right-angles to the reference plane and form a flattened portion 7, a long groove 8 and a rear groove 9 while bringing the elongated portion to a circular cross-section. A pair of lugs 17 are formed where the eye is located to assist in holding the blank while the point is formed. The lugs are cut off when the eye is pierced or in a subsequent operation.
