ABSTRACT:
The method of feeding the discs to the automatic staple or nail gun includes the steps of providing a plurality of discs stacked atop one another, shuttling a first disc from the stack to a position normal to the staple or nail expulsion path, and retaining that first disc at that position until the staple or nail is expelled from the gun. The apparatus includes a shuttle which is moved from a position immediately below the stack of discs to a second position at which the disc, carried by the shuttle carriage, is grasped by a clip. The clip retains the disc in a position normal to the path of staple or nail expulsion. The discs have dimples protruding from both planar surfaces of the disc. The dimples are predisposed in a predetermined pattern such that the protrusions from one surface form a pattern which is non-equivalent to the pattern formed by the protrusions extending from the other surface of the disc. This dimple pattern is in a peripherally spaced band on the disc. The shuttle carriage is configured to carry these discs on planar surfaces beyond the band of dimples.
