Description

1324226 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a finished fixture. More particularly, the present invention relates to a finished nail strip that is formed with an embossed strip for use in a fixture driving tool. [Prior Art]

Fast-acting fixture-driven tools are widely used in the industry. In order to use these tools, a plurality of nail systems are assembled into strips that are inserted into a magazine of the tool. These strips are flat and the nails or other fixtures are held parallel to each other. These nails are assembled in a staggered or stepped pattern such that the nails form an angle primarily with respect to the longitudinal direction of the adjustment. In known finishing nails, the angle is between about 10 and 40 degrees, and preferably between 15 and 25. An in-depth discussion of such a fixture is provided in US Patent No. 5,733,085, the disclosure of which is incorporated herein by reference.

The built-in nails are assembled using a strip or extruded plastic material. The plastic (or polymer) in the plastic strip is cooled or sized to hold the plurality of nails in strip form for use in the tool. The strip is formed of paper or other cardboard, wherein the kraft paper or other cardboard has a plastic (polymer) adhesive on one surface thereof, and the adhesive is heated when it is attached to the hot nail and adheres when it is cooled. To the nails. The strip has the advantage of reducing debris, which is when the tool is activated and the nail is driven into the material to be fixed (typically wood) 1324226

form. However, it has been observed by the strap that the strips will flex and tend to be pressed over each other. This is the so-called creping situation and has been found to be one of the biggest causes of tool clogging and fixture failure, and the creping increases as the nails are further apart. One way to solve the problem of creping is to use a thicker belt 1 which has a relatively large amount of adhesive material on the belt (to secure the nails). However, it has been found that as the resistance of the strip to creping increases, the force required to separate the strip from the strip and the shear band (e.g., resistance to shear) also increases. Therefore, the nail tends to remain fixed to the belt and the tool may become clogged. Therefore, there is a need for a tape finishing system for a strip type fixture that reduces the tendency of the nail strip to crease in the tool magazine. It is desirable that such a system can reduce the tendency to squat when the tool is activated without increasing the shearing force required to properly separate the nails in a predetermined manner. More desirably, such a system includes a belt having a thickness that is several times the thickness of the plain belt without having to increase the paper thickness or weight. More desirablely, such a system can reduce the tendency to squat without substantially increasing the paper size or stickiness/dose. SUMMARY OF THE INVENTION A fixture assembly for use in a fixture drive tool. The assembly includes at least: a row of fixtures configured to be substantially parallel to one another; and a strip having a support substrate and a layer of adhesive on the support substrate. This assembly forms a finishing nail strip. 6 1324226

The substrate has a long dimension that extends generally in the direction of the column of fixtures. The material has embossing formed therein. The adhesive composition is bonded to the anchors and the fixtures are maintained in a substantially parallel configuration in the column. The embossing in the strip reduces the tendency of the nail strip to crease and reduces the need to properly separate the nail from the cut of the strip without substantially increasing the tape or stick amount. The embossing provides a final tape thickness that is seven times the thickness of the plain (non-embossed) tape. The embossed pattern produces a three-dimensional geometry that increases the stiffness of the belt and increases the overall thickness of the nail strip. The strip is formed to have a diamond pattern embossing. The diamond pattern is a repeating stone pattern that defines the primary and secondary axes. The main axis can be formed to run on the edge of the strip. Alternatively, the fixtures are arranged at an angle relative to the strip length dimension and the primary or secondary shafts are disposed substantially parallel to the fixtures, or at an angle (e.g., 90 degrees). The strip includes a plurality of ribs that extend between the embossments to the primary or secondary shaft. Various alternative embossing patterns can be used, such as a rectangular pattern, a hexagonal (honeycomb) pattern, a circular pattern, or a combination of the above, which allows the plastic material to be moved (or guided) into the rib block (embossing). The embossing depth can be greater to provide the desired overall strip or nail strip thickness. These and other features and advantages of the present invention will become more apparent from the detailed description and appended claims. [Embodiment] The substrate is drilled in a flat shape to the corner material. 7 1324226 Although the invention may comprise various types of embodiments, a preferred embodiment is shown in the drawings and will be described herein. The present disclosure is an example of the invention and is not intended to limit the invention to the particular embodiments illustrated. It should be understood that the [embodiments] of the present specification are intended to meet legal requirements and are not intended to be construed as limiting the subject matter disclosed herein.

Referring to the drawings, and in particular to Figure 1, there is shown a nail strip 10 having a tape finishing system 12 having an embossed tape pattern 14 to embody the principles of the present invention. Bar 1 includes a plurality of fixtures 16, such as the nails depicted, the nails being configured to be parallel to each other. As can be appreciated by those skilled in the art, the nail 16 is shown as a full head nail rather than a D-head nail. Therefore, the nail 16 provides increased retention characteristics (this is due to the increased surface area of the nail 16 from the nail). However, it will be appreciated that the use of a full-head nail 16 must be such that the strip 10 is manufactured with a slightly larger distance between the nails 16 (axis A 丨 6) to accommodate a larger nail 16 .

The nails 16 are finished by the strips 18 and are fixed to each other. A strip of 18 can be placed along each side of the nail strip 10. The strip 1 8 is adhered to the peripheral side 20 of the nail 16 by an adhesive 2 2 . Any of various known adhesives may be used, such as extrudable polyolefins, such as modified maleic anhydride, and other compounds such as, but not limited to, polyethylene (especially high density polyethylene) 'polypropylene , copolymers of ethylene with other alpha-olefins (eg linear low density polyethylene), copolymers of propylene with other alpha-dilute hydrocarbons (eg linear low density polyethylene), ethylene and ethylenically unsaturated esters and their derivatives 8 1324226 copolymer (eg ethylene-vinyl acetate copolymer), and mixtures comprising any of these polymers. Adhesive 22 can be applied by extrusion, coextrusion, spraying, or various known coating processes. Those skilled in the art will appreciate that a laminate formed from a plurality of layers of similar or dissimilar materials can be used to form the belt to achieve the desired result.

The tape strip 18 is formed to have an embossed pattern 14 therein. The pattern (i.e., the diamond pattern) has diamond-shaped embossments 24, each having a primary axis (labeled 26) and a primary axis (labeled 28). This diamond pattern can be a repeating diamond pattern. Advantageously, the embossing 2 4 causes the belt 18 to have a thickness t! 8, wherein t! 8 is a multiple of a plain belt thickness. Of course, the thickness is actually determined by the embossing pattern and the embossing depth. The embossing 24 produces a ribbed pattern or profile having a three-dimensional geometry that increases the stiffness of the belt 18. This reduces the chance of a strip, especially as the distance between the nails 16 increases.

The embossed strip 18 provides another less obvious advantage. The nail strips 10 are used in a variety of staples, and conversely, nails of various sizes can be used for the staples. The width of the nail box can be changed to accommodate these different sizes of nails. Therefore, there is a very small space between the nail strip 10 and the wall of the cassette, or a considerable distance between the nail strip 10 and the wall of the cassette. It will be appreciated that the thickness of the strip 10 is desirably as large as possible and is not so large as to be bound to the wall of the cassette. This avoids the side-by-side overlap of the nail strips 1 . Therefore, it is desirable to increase the overall nail strip 10 thickness without adding other characteristics (eg, to remove the nail 16 from the strip 10 1324226

Separate the shearing force). This embossing 14 provides the thickness (and increased stiffness) of the booster without adding other undesirable characteristics in equal amounts. For example, what was found was that because the amount of adhesive (plastic) did not increase, the required shear force did not increase. In fact, it was found that the force required to cut the nail 16 into the strip was required. Relative to a plain strip system actually fell. A weight impact device 200 is used to determine the comparative difference in force, which is the force required to separate the nail from a plain strip and a embossed strip in accordance with the principles of the present invention. The device 200 shown in Fig. 9 includes an exemplary staple smashing box 202 that is mounted to a bracket 204. A scale tube guide 206 carries a 4 ounce weight 208 and has a drive member blade 210 mounted to the bottom end. The weight 208 and the driver blade 210 are raised to a specified height and "dropped" such that the blade 210 strikes the nail 116. It is necessary to separate the nails 16 from the open strips. The height of the weights of the weights of 20 is measured for the embossed strips and 12 shots are measured for the plain strips. At the time of testing, a plain embossed strip having a thickness of 0.023 吋 and a diamond embossed strip having a thickness of 0.02 3 进行 were required to cut the nail 1 ό open strip 10 . The height of the cut is measured. Table 1 shows the results. Table 1 Shearing drop height drop number embossed belt drop height (吋) Simple belt drop height (吋) 1 39 53 2 39 48 3 39 48 10 1324226 4 39 48 5 42 43 6 39 48 7 39 48 8 39 48 9 36 48 10 36 43 11 39 48 12 42 - Average 39 47.5

As can be seen from the results, the height of the shear embossed tape is consistently smaller than the height of the sheared plain tape. The percentage difference value is calculated as: % difference value = [(mean < *** an average * u) / mean difference value. This indicates that the embossed strip is required to be compared with the plain strip. The shear force of the nail separation strip is substantially reduced.

In an exemplary diamond pattern, the belt 18 can be formed such that the primary or secondary shaft 28 is parallel to the edge 30 of the belt 18 such that the diamond pattern 14 falls within the edge or rim of the belt 18. Alternatively, as shown in Figures 2 and 2, the strap 118 can be formed such that the diamond pattern 114 is skewed relative to the length L118 of the strap 118. In such a configuration, the primary shaft 126 can be laterally aligned, and preferably perpendicular to the longitudinal axis A!6 of the nail 16. In this manner, the secondary shaft 128 extends parallel to the shear line 132 formed when the nail 16 is separated from the strip 10. Compared to the known plain or flat strips, the belts 18, 118 are new 11 1324226

Ying's embossing 24, 1 24 offers many advantages. First, the embossments 24, 124 provide the bending resistance of the belts 18, 1 18 and, when formed as part of the nail strips 10, help reduce the tendency of the nail strips 10 to smash. In addition, the diamond patterns 24, 124 provide a plurality of points where the strips 18, 118 tend to shear, or frangible regions 3 2, 1 3 2, such that when the nails 16 are driven away from the remainder of the strip 10 Promote the separation of the nails 16. Thus, the embossed patterns 14, 114 provide strength in the direction of compression (to avoid creping) and provide separation lines 32, 132, wherein the strips 18, 1 18 can be torn along the separation lines 3 2, 1 3 2 from. As shown in Figure 3 (and Figure 5), a reinforcing rib 34 (and 434) can be formed in the belts 18, 118 along the major axes 26, 126 of the diamond embossments 24, 124. The ribs 34 provide additional rigidity and strength to the belts 18, 118 to further reduce the potential for creping.

In the embossed strips 18, 1 18, a 3/4 inch wide kraft paper web substrate 36 is formed having diamond pattern embossing 24, 124» paper 36 of 30 pounds and about 0.003 inch (3 mils). ) Kraft paper of thickness. Each of the diamonds 24, 124 has a minor axis of about 0. 06, 4, and a size of about 8,9,9, and a major axis of 26, 126. The adhesive layer 22 is a thermally reactive high density polyethylene based material which is applied to the substrate at a thickness of from 3 6 to about 19 mils after embossing. In the illustrated strip 10, the nail 16 is disposed at an angle a of about 20 degrees with respect to the transverse direction 38 of the strips 18, 11 8; however, other angles a can be contemplated for use in the present invention. One of the advantages of the 20 degree finishing system is that as the angle a decreases, more nails can be "packed" within a shorter linear (measured belt) distance. Therefore, the number of nails in the 20 degree finishing system 12 1324226 is greater than the number of nails in the 30 degree finishing system.

Figures 4-5 illustrate two square, 45 degree embossed patterns 3 1 4, 414 in which the embossed lines or fold lines 324 are centered at 0.130 且 and the embossed lines have A width of about 0.02 0 吋 (20 mils). The embossed pattern 314 is a 45 degree pattern and the machine direction is MD in the direction indicated by the arrow. The depth of the embossing 324 is, for example, about 16 mils to 22 mils. The pattern 414 of Fig. 5 shows a 45 degree pattern 414, the embossed line or the broken line 424 is located at the center of 0.13 0 且 and the embossed line has a width of about 0 _ 0 2 0 吋 (20 mils) and A depth of about 16 mils to 22 mils. The pattern 414 of Fig. 5 also includes support lines 434 in the staggered pattern, the support lines 434 extending in the corners to corners of the squares along the process direction MD. Support lines 34 and 434 provide additional rigidity to further reduce the chance of the strip 1 picking up. As shown in FIG. 7, the pattern 514 can be formed such that the embossed lines 524 are not straight (ie, not collinear) at the intersection, but are offset from adjacent lines to be more intensively effective (eg, Fall down) the ability to shear the belt while maintaining the longitudinal stiffness of the desired belt.

Various embossing patterns have been successfully formed, including square embossed patterns with 25 and 35 mil depth, square embossed patterns with 25 mil depth and staggered support lines (Fig. 5), slanted Diamond pattern with 23 degree tilt and 35 mil depth, reinforced (with support line) slanted diamond pattern with 23 degree tilt and 35 mil depth, and slanted diamond pattern with 67 degree back side tilt and 3 5 mil depth. The angle of inclination is the angle measured between the main axis of the diamond and the edge of the strip. Figure 8 shows yet another belt 614, one or more of the longitudinal embossing 13 1324226

The 6 2 4 extends along the length or along the longitudinal axis of the belt 6 1 4 . It will also be appreciated by those skilled in the art that the "paper" tape base 36 can be formed from materials other than paper or cardboard, such as polyester or other film-forming polymers or fabrics (e.g., cloth). ). In such a strip, the embossments 14, 114, 314, 414, 514, 614 may be fabricated during manufacture (eg, after the extrusion step of the adhesive being extruded onto the tape (to form a laminate)) or after a process The middle is formed in the belt. It is also contemplated that the substrate is provided, embossed is formed, and the adhesive is applied. In the process, the embossing is formed after applying the adhesive to the substrate and is formed to a depth of from about 16 mils to about 35 mils. In the manufacture of the nail strips 10 (2), the belts 18 are attached to the heated nails 16 and are guided to a drum with the belt 18 pressed to the nails 16. In one of the methods of making the strip 18, the edge of the strip 18 is forced with greater force than at the center. It has been found that the embossed belt nail strip 1 has the additional advantage of reducing the amount of debris that is generated when the nail gun is activated. A nail strip having a nail amount is shot from the nail and the resulting debris is collected. The strip includes a plastic finishing system, a non-embossed (plain) strip and an embossed strip. The pieces from each piece are weighed. For the plastic system, each nail strip produced 4.3 1 8 grams of debris, the plain belt produced 0.5586 grams of debris, and the embossed belt produced 0.2137 grams of each nail strip. It will be appreciated that the lesser the fragments produced, the more advantageous the embossments 14, 114, 314, 414, 514, 614 are not limited to the repeated diamond patterns 24, 124, 324, 424, 524 shown. In fact, many other embossed shapes and contours can be expected, such as a cross, a six-piece case with a strip shape 1 that will be in the same shape, a smashed I 〇 & 角 角 14 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 shape. These and other shapes can be used to form the embossed patterns 14, 114, 314, 414, 514, 614, and are within the scope and spirit of the present invention.
