A production line for recycling and processing waste materials of steel rolling, the production line including: an electromagnetic hoisting equipment; a conveying platform; a clamping-and-feeding device; a segmentation shear; a swing conveyor device; a pushing device; a rolling-type shearing machine; a chain-type conveyor track; a material guiding device; two shredding-type shearing machines; and a scrap collection device. The electromagnetic hoisting equipment is connected to the conveying platform, and is configured to hoist waste materials of steel rolling to the conveying platform; the conveying platform is connected to the clamping-and-feeding device, and is configured to convey the waste materials to the clamping-and-feeding device; the segmentation shear cooperates with the clamping-and-feeding device and is configured to segment the waste materials of steel rolling into steel plates; the pushing device is configured to push the steel plates to the rolling-type shearing machine.

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.
