the present invention as embodied in the strip illustrated
in FIG. 1 comprises a plurality of conventional nails
formed into, an array in which they are arranged in side

taining live to two hundred nails, depending upon the
nail size, may conveniently be employed in this fashion.

the machine, the strip illustrated in FIG. 1 is preferably‘
coiled up as shown in FIGS. 3 or 4 of the drawing.
The coil may take one of two convenient ‘forms which
tory results are obtained with ?at wire as well as with
round wire. in some situations, particularly in the case
of large nails or spikes it may 1be desirable to employ
three or even more wires for securing the nails together.
The gauge of the wire is not critical, being selected to
provide the maximum number of nails in a given volume.
As illustrated in P16. 3, the heads of the nails in each
convolution of the coil are in overlapping relation with;
the heads of the nails in adjacent convolutions. In this:

enough so that the wire may readily be broken to permit
the individual nails to be detached during operation of
the nailing machine. In the case of small nails, the wire

or spikes it may be as heavy as 0.050 inch.
