Abstract
An apparatus having a frame; a shuttle member, adapted to receive and hold a needle blank, and movably mounted to the frame; a clamp member detachably mounted on the frame for supplying needle blanks to the shuttle member; a transfer mechanism mounted on the frame for facilitating the transfer of the needle blanks from the clamp member to the shuttle member; a press mechanism for imparting first flat surfaces to first opposing sides of the needle blanks held by the shuttle member; a mandrel mounted on the frame for imparting an arcuate profile to the needle blanks; a transport mechanism for transporting the needle blanks from the shuttle member to the mandrel; and a needle side press for imparting second flat surfaces to second opposing sides of the needle blanks. A method of forming a curved, rectangular bodied needle from substantially round-elongated needle blanks is also disclosed and comprises the steps of: transferring needle blanks from a clamp to a holding shuttle having die surfaces on needle engaging faces thereof; flat pressing first opposing sides of the needle blanks between die surfaces; transporting the needle blanks from the shuttle onto a rotatable mandrel; curving the needle blanks between the rotatable mandrel and a reciprocable belt; rotating the needle blanks about the mandrel and adjacent side press dies and depositing the needle blanks therebetween; and side pressing second opposing sides of the needle blanks between side press dies.
