Definitions

  • the present invention pertains to collated fasteners.
  • the present invention pertains to a collated nail strip formed with an embossed tape, for use in a fastener driving tool.
  • Fast-acting fastener driving tools are in widespread use in the construction industry.
  • the nails are assembled in strips that are inserted into a magazine of the tool.
  • the strips are flat and the nails or other fasteners are held parallel to one another.
  • the nails are assembled in a staggered or stepped manner such that the major axis of the nail forms an angle to the longitudinal direction of the strip.
  • the angle is about 10 degrees to 40 degrees and preferably between 15 degrees and 25 degrees.
  • presently known collated nails are assembled using tape strips or an extruded plastic material.
  • the plastic (or polymer) in the plastic- formed strips is cooled and hardens to hold the nails in the strip form for use in the tool.
  • the tape strips are formed from a kraft paper or other paperboard material having a plastic (polymer) adhesive on a surface thereof that is heated on contact with hot nails and, as it cools, adheres to the nails.
  • the tape strips have the advantage of minimizing the debris that is formed as the tool is actuated and the nails are driven into the material (typically wood) to be fastened.
  • the tape strip it has been observed that the strip can flex and tend to advance on each other. This is a condition known as corrugation and has been found to be one of the greatest causes of tool jamming and fastener failure, and increases as the nails are spaced farther apart.
  • a paper tape collation system for strip-formed fasteners that reduces the tendency for the nail strip to corrugate in the tool magazine.
  • such a system reduces the tendency to corrugate without increasing the shear required to properly separate the nail from the strip in a predetermined manner as the tool is actuated.
  • such a system includes a tape that has a thickness several times greater than plain tape without increasing the paper thickness or weight. More desirably, such a system Teduces the tendency to corrugate without substantially increasing the size of the tape or the amount of adhesive.
  • a fastener assembly is for use in a fastener driving tool.
  • the assembly includes a row of fasteners arranged substantially parallel to each other and a strip having a supporting substrate and an adhesive composition thereon.
  • the assembly forms a collating nail strip.
  • the substrate has an elongated dimension extending generally in the direction of the row of fasteners.
  • the substrate has embossings formed therein.
  • the adhesive composition is bonded to the fasteners and maintains them in the substantially parallel arrangement in the row.
  • the embossings in the strip reduce the tendency of the nail strip to corrugate and decreasing the shear required to properly separate the nail from the strip and without substantially increasing the size of the tape or the amount of adhesive.
  • the embossings provide a resulting tape thickness that is several times greater than plain (non-embossed) tape.
  • the embossing pattern produces a 3-dimensional geometry that increases the rigidity of the tape and increases the overall thickness of the nail strip.
  • a present strip is formed having diamond pattern embossings.
  • the diamond pattern is a repeating diamond pattern that defines major and minor axes.
  • the major axis can be formed parallel to an edge of the strip.
  • the fasteners are positioned at an angle relative to the elongated dimension of the strip and the major or minor axis is positioned substantially parallel to the fasteners, or at an angle such as 90 degrees.
  • the strip can include ribs extending between embossings at the major or minor axes.
  • embossings patterns can be used, such as a rectangular pattern, a hexagonal (e.g., honeycomb) pattern, a circular pattern or some combination thereof that allows plastic material to be moved (or introduced) into the rib sections (the embossings). Embossing depths can vary to provide a desired overall tape or nail strip thickness.
  • FIG. 1 is a plan view of one embodiment of a nail strip having a paper tape collation system having an embossed tape pattern embodying the principles of the present invention
  • FIG. 2 is a plan view of a second embodiment of the paper tape collation system, FIG. 2A being a second view of this embodiment;
  • FIG. 3 is an enlarged view of an isolated section of the embossed diamond patterns
  • FIG. 4 is a schematic illustration of a 45 degree square embossing pattern
  • FIG. 5 is a schematic illustration of a 45 degree square embossing pattern with an alternating integrated brace
  • FIG. 6 is an illustration of a cross-section of an exemplary section of embossed tape
  • FIG. 7 is a schematic of an alternate pattern in which the embossing lines are offset from one another at the line junctures;
  • FIG. 8 is an illustration of yet another alternate pattern in which the embossing is a single longitudinal embossing.
  • FIG. 9 is an illustration of a testing device that was used to compare the shear required for an embossed tape strip to that required for a plain tape strip.
  • FIG. 1 there is shown a nail strip 10 having a paper tape collation system 12 with an embossed tape pattern 14 embodying the principles of the present invention.
  • the strip 10 includes a plurality of fasteners 16, such as the illustrated nails disposed parallel to one another.
  • the illustrated nails 16 are full head nails, rather than D-head nails. Accordingly, the nails 16 provide increased holding characteristics (due to the increased surface area of the nail 16 head).
  • full head nails 16 requires that the strip 10 is fabricated with a slightly greater distance between the (axes Ai 6 of the) nails 16 to accommodate the larger nail 16 heads.
  • the nails 16 are collated and held to one another by tape strips 18.
  • a strip 18 can be disposed along each side of the nail strip 10.
  • the tape strips 18 are adhered to the outer peripheral sides 20 of the nails 16 by an adhesive 22.
  • Any of a variety of known adhesives 22 can be used, such as extrudable polyolef ⁇ ns, such as maleic anhydride modified, and others, such as, but not limited to polyethylene (especially high density polyethylene), polypropylene, copolymers of ethylene with other alpha-olefins (for example, linear low density polyethylene) copolymers of propylene with other alpha- olefins, copolymers of ethylene with ethylenically unsaturated esters and their derivatives (for example, ethylene vinyl acetate), and mixtures including any of these polymers.
  • polyethylene especially high density polyethylene
  • polypropylene copolymers of ethylene with other alpha-olefins (for example, linear low density polyethylene) cop
  • the adhesive 22 can be applied by extrusion, coextrusion, spraying or a variety of other known application processes. It will be appreciated by those skilled in the art that a lamination formed from multiple layers of similar or dissimilar materials can be used to form the tape to achieve a desired result.
  • the paper tape strips 18 are formed with the embossed pattern 14 therein.
  • One pattern a diamond pattern, has diamond-shaped embossings 24, each having a major axis (as indicated at 26) and a minor axis (as indicated at 28).
  • the diamond pattern can be a repeating diamond pattern.
  • the embossings 24 present a tape 18 with a thickness tig that is several times greater than that of a plain tape.
  • the actual thickness will of course depend upon the type of embossing and the depth of the embossing.
  • the embossing 24 produces a ribbed pattern or profile having a 3-dimensional geometry that increases the rigidity of the tape 18. This reduces the opportunity for the strip 10 to corrugate, particularly as the distance between the nails 16 increases.
  • the embossed tape 18 provides another advantage that may be less apparent.
  • Nail strips 10 are used in a variety of nail guns, and conversely, nail guns can use a variety of different sizes of nails.
  • the widths of the magazines of the nail guns vary to accommodate these different size nails. Accordingly, there may be little space between the nail strip 10 and the magazine wall or there may be a fairly sizable distance between the strip 10 and the wall.
  • the present embossings 14 provide this increased thickness (as well as increased rigidity) without a commensurate increase in some of the other, non-desired characteristics. For example, it has been found that because the amount of adhesive (plastic) is not increased, the required shear has not increased. In fact, it was found that the force required to shear the nail 16 from the strip 10 actually decreased compared to a plain tape strip.
  • a weight impact fixture 200 was used to determine the comparative differences in force required to separate a nail from a plain strip and an embossed strip in accordance with the principles of the present invention.
  • the fixture 200 illustrated in FIG. 9 includes an exemplary nail gun magazine 202 mounted to a stand 204.
  • a graduated tube guide 206 carries a 4 ounce weight 208 with a driver blade 210 mounted to a bottom end. The weight 208 and driver blade 210 were raised to a designated height and "dropped" so that the blade 210 struck the nail 16 head.
  • the tape 18 can be formed with the major axis 26 or minor axis 28 parallel to the edges 30 of the tape 18, e.g., so that the diamond pattern 14 falls within the edges or margins 30 of the tape 18.
  • the tape 118 can be formed with the diamond pattern 114 on a bias relative to the length Lu 8 of the tape 118.
  • the major axis 126 can be oriented transverse, and preferably perpendicular to the longitudinal axis Ai ⁇ of the nail 16.
  • the minor axis 128 extends parallel to the shear line 132 that is formed as the nail 16 is separated from the strip 10.
  • the novel embossings 24, 124 in the tape 18, 118 provide a number of advantages over known flat or planar tape strips.
  • the embossings 24, 124 provide resistance to bending of the tape 18, 118 per se, and, when forming part of the nail strip 10, help to reduce the tendency of the nail strip 10 to corrugate.
  • the diamond pattern 24, 124 provides points at which the tape 18, 118 will tend to shear, or frangible regions (32, 132), to facilitate separation of the nail 16 as it is driven from the remainder of the strip 10.
  • the embossed pattern 14, 114 provides strength in the compressive direction (to prevent corrugation) and provides separation lines 32, 132 along which the tape 18, 118 can be .torn.
  • the rib 34 provides additional rigidity and strength to the tape 18, 118 to further reduce the potential for corrugation.
  • a 3 A inch wide kraft paper tape substrate 36 having the diamond pattern embossing 24, 124 was formed.
  • the paper 36 was a 30 Ib. kraft paper with thickness of about 0.003 inches (3 mils).
  • the diamonds 24, 124 each had a minor axis 28, 128 dimension of about 0.064 inches and a major axis 26, 126 dimension of about 0.099 inches.
  • the adhesive layer 22 was a heat reactive high density polyethylene based material applied to the substrate 36 to a thickness of about 19 mils after embossing.
  • the nails 16 are positioned at an angle ⁇ of about 20 degrees to the transverse direction 38 of the strip 18, 118; however, other angles ⁇ are contemplated for use with the present invention.
  • One of the advantages of the 20 degree collation system is that a greater number of nails can be "packed" in less linear (tape measured) distance as the angle ⁇ decreases. As such, the number of nails in a 20 degree collation is greater than the number of nails 16 in a 30 degree collation system.
  • FIGS. 4-5 illustrate ' two square, 45 degree embossing patterns 314, 414, a first 314 in which the embossing lines or creases 324 are on 0.130 inch centers and the embossing lines have a width of about 0.020 inches (20 mils).
  • the embossing pattern 314 is a 45 degree pattern and the machine direction is illustrated by the arrow at MD.
  • the depth of the embossings 324 are at, for example, about 16 mils to 22 mils.
  • the pattern 414 of FIG. 5 illustrates a 45 degree pattern 414 with the embossing lines or creases 424 on 0.130 inch centers and having a width of about 0.020 inches (20 mils), with depths of about 16 mils to 26 mils.
  • the pattern 414 of FIG. 5 also includes the brace 434 in an alternating pattern that extends corner to corner of the squares in the machine direction MD.
  • the braces 34 and 434 provide additional rigidity to further reduce the opportunity for the strip 10 to corrugate.
  • the pattern 514 can be formed such that the embossing lines 524 are not straight at the junctures 526 (e.g., not collinear), but rather are offset from adjacent lines to further enhance the ability to effectively (e.g., cleanly) shear the tape, while maintaining the desired longitudinal rigidity of the tape.
  • FIG. 8 Another tape 614 is illustrated in FIG. 8 in which one or more longitudinal embossings 624 extend along the length or along the longitudinal axis of the 614.
  • the "paper" tape substrate 36 can be formed from materials other than paper or paperboard-based materials, such as polyester and other film forming polymers or fabrics, such as cloth.
  • the embossing 14, 114, 314, 414, 514, 614 can be formed in the strip during manufacture, such as following an extrusion step in which adhesive extruded onto the tape (to form the lamination) or later in a post-manufacture process.
  • the substrate is provided, the embossings formed and the adhesive applied.
  • the embossings are formed after application of the adhesive to the substrate, and are formed to a depth of about 16 mils to about 35.
  • the tape 18 is applied to heated nails 16 and introduced to a roller to press the tape 18 to the nails 16.
  • the tape 18 is pressed with a greater force at the edges than in the center of the tape 18.
  • the embossed tape nail strip 10 has the additional advantage of reducing the amount of debris that is generated upon actuation of the nail gun. Strips of nails having an equal number of nails were fired from a nail gun and the debris generated was collected. The strips included a plastic collation, a non-embossed (plain) tape strip and an embossed tape strip. The debris from each was weighed. The plastic collation generated 4.318 grams of debris per strip of nails, the plain tape generated 0.5586 grams of debris and the embossed tape generated 0.2137 grams of debris per nail strip. It will be appreciated that it is more advantageous to have a lesser amount of debris generated.
  • the embossings 14, 1 14, 314, 414, 514, 614 are not limited to the illustrated repeating diamond pattern 24, 124, 324, 424, 524. In fact, many other embossing shapes and profiles are anticipated as set forth above, such as, cruciform shapes, hexagonal shapes, octagonal shapes and round shapes. These and other shapes can be used to form the embossed pattern 14, 1 14, 314, 414, 514, 614 and are all within the scope and spirit of the present invention.
