A method and apparatus for providing a coating on the exterior surfaces of a plurality of elongate members, such as wires, including positioning a plurality of elongate members substantially parallel to each other, coating the exterior surfaces of each member with a coating, removing any excess coating from desired portions of each member and curing the coating to adhere the coating to each member.

Nails having radially offset, circular heads are manufactured from a malleable wire. The wire is clamped so that a leading portion extends axially from a clamping mechanism. The extending portion is bent at an acute angle relative to a clamping axis. The extending portion is cut so as to form a pointed end thereon and so as to leave a bent stub extending at such an angle. Such a nail head is formed from the stub, which is pressed by a punch into a cavity defined by the clamping mechanism, and which is deformed when pressed thereinto. The cavity has a fully circular, offset margin. The punch has a face covering the cavity. Once released, the wire is fed axially until a leading portion extends as before. These operations are repeated to form a similar nail in each repetition. A novel apparatus for carrying out these operations is disclosed.

Wire nails are collated by means for conveying the nails in a specified manner and by means comprising a wheel for engaging keyways defining flat surfaces on the shanks of the nails. Each nail is rotated by the wheel, about an axis of the shank of such nail, to such extent as may be then necessary to orient the keyways of such nail and of other nails with such surfaces defining a plane. The wheel fits between end surfaces defined by the keyways so as to cause the keyways that have been engaged by the wheel to define a continuous channel.
