Embossed tape collating strip for nails

a collating strip and embossed tape technology, applied in the field of collating fasteners, can solve the problems of nail strip flexing and prone to advance on each other, tool jamming and fastener failure, and nail tended to remain attached, so as to reduce the tendency of nail strips, increase the size of tape or the amount of adhesive, and reduce the effect of shear

Benefits of technology

[0009] 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.
[0010] 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.

Problems solved by technology

However, with 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.
As such, nails tended to remain affixed to the tape and jamming of the tool occurred.

Abstract

A fastener assembly for use in a fastener driving tool includes a row of fasteners arranged substantially parallel to each other and a strip having a supporting substrate and an adhesive composition thereon. The supporting 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. A method for making the embossed strip is also disclosed.

Description

BACKGROUND OF THE INVENTION [0001] The present invention pertains to collated fasteners. More particularly, the present invention pertains to a collated nail strip formed with an embossed tape, for use in a fastener driving tool. [0002] Fast-acting fastener driving tools are in widespread use in the construction industry. For use in these tools, 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. In presently known collated nails, the angle is about 10 degrees to 40 degrees and preferably between 15 degrees and 25 degrees. An in-depth discussion of such fasteners is provided in U.S. Pat. No. 5,733,085, to Shida, which is incorporated herein by reference. [0003] Presently known collated nails are assembled using tape st...
