Apparatus and method of making a heel-less nail
A full-round head nail having an offset head is configured with a gusset formed integrally between an undersurface of the offset head and a superior portion of a shank. The head of the nail is relatively thin, and the shank is positioned radially off center of the round head such that no heel is formed at a point tangential to both the head and the shank. The gusset has a lofted surface tapering radially from a roundness at the zero heel to a taper at the toe. The gusset reinforces the junction of the shank with the head, supports the toe of the head, and distributes the force of a load on the head through a longitudinal axis of the shank, preventing the toe from bending or yielding and prevents the shank from yielding to the stresses of the load applied.
1. A method for making a heel-less nail, the method comprising the steps of:
providing a die configured for cold forming, the die having a first and a second gripper, the first gripper configured with a first cavity complimentary to a portion of a nail shank and a first cavity complimentary to a portion of an nail gusset, the second gripper configured with a second cavity complimentary to second portion of the nail shank and a second cavity complimentary to second portion of the nail gusset, wherein the second cavity complimentary to the second portion of the nail gusset and the second cavity complimentary to the second portion of the nail shank have a region of collinearity along a plane defined by a surface of the second gripper;
inserting a wire into the die, the wire having an exposed end;
prebending the wire to create a precise pre-bent form using a first roller; and
forming the nail gusset, and a round nail head using a second pressure roller.
2. A method for manufacturing a heel-less nail, the heel-less nail having a full-round head, a shank, and a gusset, the method comprising:
positioning a wire segment in a die wherein a portion of the wire segment is positioned outside of the die;
forming the wire segment into a blank using a pre-bend roller, the wire segment containing the precise cubic material volume needed to form the gusset and the head;
compressing the wire segment in the die to form the full round head and the gusset via a compression roller, wherein the head and the gusset have a region of collinearity along a plane defined by a surface of the die.
