Method and apparatus for feeding tabs or discs to an automatic staple or nail gun

摘要

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.
