- (57) Abstract
A continuous strip of T-Nuts formed on a common strip of metal. Each T-Nut of the strip of T-Nuts is integrally connected to the next adjacent T-Nut by carry tabs. The carry tabs can be frangible themselves or contain a frangible portion. Each T-Nut includes a cylindrical bore therein and a threaded interior. A mechanism feeds and severs the endmost T-Nut in endwise fashion. The mechanism to feed and sever the endmost T-Nut includes a cutting blade positioned vertically below the frangible portion of the carry tab. A shearing ram having a guide positioned axially in line with the cylindrical bore in the endmost T-Nut is adapted to move vertically from an upper to a lower position to engage the cutting blade with the frangible portion and sever the endmost T-Nut.

Description
This application claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 61/433,300 filed Jan. 17, 2011. U.S. Provisional Patent Application Ser. No. 61/433,300 filed Jan. 17, 2011 is incorporated in its entirety by reference hereto.
The invention is in the field of fasteners.
Existing collated fasteners are manufactured and then collated using a secondary process. One process uses a progressive die method to cut the T-Nuts off from the steel or stainless steel strip and then tap the threads in a secondary process. The secondary process commonly uses glue to hold the fasteners together for later dispensation. Fasteners which are glued together include staples, nails, screws, clips, etc.
One known method for collating T-Nuts includes adhering the T-Nuts to tape and rolling them into a coil during a secondary operation. FIG. 13 is a view 1300 illustrating a prior art backing strip 1301 securing individual T- Nuts 1302 thereto by means of adhesive as illustrated in U.S. Pat. No. 5,214,843. FIG. 13A is a view 1300 A illustrating a prior art device illustrated in U.S. Pat. No. 5,214,843 with wires 1304, 1305 welded to individual T- Nuts 1302.
Presently known methods of collating T-Nuts using tape have several disadvantages. First, T-Nuts can easily become detached or ‘unstuck’ from the tape. Factors such as temperature and humidity can have an adverse reaction on the adhesive properties of tape. Second, taped T-Nuts on a coil do not withstand impact well. Common forces involved with activities such as shipping and/or handling can cause T-Nuts to detach.
