摘要:
A nail having a clamp head which has a clamp with a clamp angle in a range of from 75 degrees to greater than 30 degrees. A nail stick having a collation angle which has a value greater than 25 degrees. A method of manufacturing a nail stick having a step of punching a collated band of wires to create clamp heads having clamps which respectively have a clamp angles in a range of from 60 degrees to 40 degrees.

Zur wirtschaftlichen Herstellung von Befestigungselementen (5, 6) wird ein Verfahren verwendet, bei dem an beiden Endbereichen eines die Länge von zwei Befestigungselementen (5, 6) übersteigenden Rohlings (1) je ein Kopf (2, 3) angestaucht und nach Erwärmen eines zwischen den angestauchten Köpfen (2, 3) liegenden Abschnittes (4) der Rohling (1) bis zu seiner Trennung im erwärmten Abschnitt (4) axial auseinandergezogen wird.
摘要:
The invention relates to a nail, especially for joining upper constructions (18) and lower constructions (20) consisting of the same or different materials, comprising a shaft (14) and a tip (16) which is connected to said shaft (14). The shaft (14) of the nail consists of an unhardened steel over a considerable part of its length, while the tip (16) of the nail consists of a hardened steel.
摘要:
A method and apparatus is disclosed for affixing heads (14) to headless fasteners (13) to form webs (11) thereof, wherein the headless fasteners (13) are equally spaced apart a given spacing. The web of headless fasteners (13) is conveyed to and disposed so that each of a first set of headless fasteners is disposed in an aligned relationship to corresponding ones of a plurality of "n" head affixing devices (90). The head affixing devices (90) are spaced from each other a distance equal to the product of the given spacing and ("n" ± 1). The plurality of head affixing devices (90) are actuated to fasten "n" heads (14) to their aligned fasteners (13) of the web. Thereafter, the web (11) is moved with respect to the plurality of "n" head affixing devices (90) a distance equal to the product of "n" and the given spacing to align each of a second, different set of fasteners (13) of the web (11) to corresponding ones of the plurality of "n" head affixing devices (90). The plurality of the head affixing devices (90) are actuated for a time period during which each of the present set of headless fasteners (13) is maintained in the aligned relationship with its corresponding one head affixing device (90). The web is repeatedly moved and the "n" welding devices (90) are repeatedly actuated until a head (14) is affixed to each headless fastener (13) of the web (11).

摘要:
A selectively hardened nail (10) includes a nail head (12), an elongated shank (14), and a tip (16). A portion (15) of the nail shank (14) is made harder than the remainder by selectively heat treating that portion, and cooling it. The nail has controlled bending properties. The selectively hardened portion does not significantly bend when the nail (10) is fired at a surface using a power driving tool, or during use of the nailed object.
摘要:
A nail for fixing a shoe to a hoof includes a head (20), and a shank (12) extending from the head (20) generally along a centreline (14) and terminating in a tip (13). A reaction region (24) is formed in the shank (12) adjacent the tip (13) and has a flattened profile having front and rear surfaces (25, 26) interconnected by respective edge surfaces (27, 28). In the reaction region (24) the front surface (25) is convexly curved to incline the front surface (25) relative to the centreline (14) of the shank (12) and the edge surfaces (27, 28) converge relative to each other towards the tip (13), whereby, on forcing the nail into the hoof, the reaction region (24) is adapted to produce a resultant force on the nail caused by engagement of the reaction (24) with the hoof, the resultant force being adapted to predispose the nail to bend about the rear surface (26) of the reaction region (24). Also disclosed are processes for forming a horseshoe nail.
