    摘要： There is disclosed an apparatus and method for forming curved and pointed needle blanks from a coiled length of wire needle stock material. The apparatus includes an inner mandrel having a circumferential wire receiving groove and at least one longitudinally extending broach receiving channel formed in the outer surface. The apparatus also includes an outer member having an inner surface defining a bore sized to receive the inner mandrel wrapped with wire needle stock. The outer member includes at least one longitudinal broach receiving channel formed in the outer member inner surface. The outer mandrel further includes a circumferential wire receiving groove formed in the inner surface such that, when wrapped with the length of wire needle stock material, the inner mandrel is threaded into the outer member. The apparatus further includes at least one broach which is movable within the channels to cut the length of wire needle stock into curved and pointed needle blanks. The method includes wrapping a length of wire needle stock around an inner mandrel and inserting the wire wrapped mandrel within an outer member. The method further includes moving at least one broach within a longitudinal channel formed in at least one of the mandrel and outer member to cut the length of wire needle stock into needle blanks. A needle blank formed by the apparatus and method is disclosed.

    摘要： A method and apparatus is provided for manufacturing and packaging split retaining rings quickly and economically. The rings are initially formed from work-hardened, high carbon spring steel wire by a coiling machine and collected side by side into stacks on an especially configured suspended rod such that all ring gaps within each stack are aligned with one another. The ring stack is moved on the rod to an electrically non-conductive portion thereof which is encircled by an electrically conductive coil in spaced relation thereto. Alternating current is supplied to the coil whereby the ring stack is induction heated to a predetermined temperature and thus stress relieved. Each ring stack is then moved along the rod where it is cooled, oiled, inspected and wrapped; all operations being formed with the rings remaining in their stacked position on the rod.
