Abstract
An angled strips of brads with a plurality of cohered brads having a shank with a tip portion. A head portion of at least some of the plurality of brads having a bulge protruding forwardly from the leading side thereof and extending at least partially into the trailing side of the head portion of an adjacent brad. An upper leading side portion of the head portions of the plurality of brads offset rearwardly of the leading side of the shank, whereby interlocking of adjacent head portions of the angled strip of brads is reduced. The rearwardly biased head portion is formed preferably with a rearwardly sloped riser portion of a header punch.
Claims22
An angled strip of brads formed simultaneously from a plurality of adjacently arranged parallel wires, useable in a trim nailing tool having an angled magazine for accommodating the angled strip of brads and a driver blade for shearing individual brads from the angled strip of brads, comprising:
- a plurality of brads having a shank with a tip portion and a head portion, the plurality of brads each having a leading side and a trailing side, the plurality of brads arranged adjacently, offset axially, and cohered side by side to form the angled strip of brads,
- the head portion of at least some of the plurality of brads having a bulge protruding forwardly from the leading side thereof not more than approximately 0.005 inches, and extending at least partially into the trailing side of the head portion of an adjacent brad.
An angled strip of brads formed simultaneously from a plurality of adjacently arranged parallel wires, useable in a trim nailing tool, comprising:
- a plurality of brads having a shank with a tip portion and a head portion, the plurality of brads each having a leading side and a trailing side, the plurality of brads arranged adjacently, offset axially, and cohered side by side to form the angled strip of brads,
- the head portion of at least some of the plurality of brads having a bulge protruding forwardly from the leading side thereof, the bulge of some of the plurality of brads extending at least partially into the trailing side of the head portion of an adjacent brad,
- an upper leading side portion of the head portions of the plurality of brads offset rearwardly of the leading side of the corresponding shank.
A method of forming an angled strip of brads, useable in a trim nailing tool, comprising:
- gripping a plurality of wires arranged in a strip having at least one angled axial end;
- punching end portions of the plurality of wires with a stepped header punch driven toward the angled axial end of the strip;
- forming a head portion on each of the plurality of wires with a corresponding stepped portion of the header punch and a corresponding riser portion of the header punch, the stepped portions of the header punch generally perpendicular to an axis of the corresponding wire, and the riser portions of the header punch sloped rearwardly from a leading side of the corresponding wire to a trailing side thereof;
- biasing a leading side of the head portions of the plurality of wires rearwardly toward a trailing side of the plurality of wires with the rearwardly sloped riser portion of the header punch when forming the head portions,
- whereby interlocking of adjacent head portions of the angled strip of brads is reduced.
A method of forming an angled strip of brads, usable in a trim nailing tool, comprising:
- gripping a plurality of wires arranged in a strip having at least one angled axial end;
- punching end portions of the plurality of wires with a stepped header punch driven toward the angled axial end of the strip;
- forming a head portion on each of the plurality of wires with a corresponding stepped portion of the header punch and a corresponding riser portion of the header punch, the stepped portions of the header punch generally perpendicular to to an axis of the corresponding wire, and the riser portions of the header punch generally parallel to a leading side of the corresponding wire;
- biasing a leading side of the head portions of the plurality of wires rearwardly toward a trailing side of the plurality of wires by driving the header punch along a path at an angle relative to the axis of the plurality of wires when forming the head portions,
- whereby interlocking of adjacent head portions of the angled strip of brads is reduced.
