A method for reinforcing a substrate or textile of a core structure of a component with the following method steps: a continuous semi-finished product is fed, via a feed means, into a cartridge of a conveying means which comprises a plurality of cartridges; the continuous semi-finished product is cut to length using a cutting means in order to produce a cut, reinforcing semi-finished product which is received in the cartridge; the cartridge is conveyed to a machining means; the cut, reinforcing semi-finished product is sharpened using the machining means; the cartridge is conveyed to a textile or substrate to be reinforced of a core structure; and the sharpened semi-finished product is shot into the textile or substrate of a core structure by a stud-shooting means.

Method and means of manufacturing ties, fasteners and rods (15) having a plurality of longitudinal threads by forcing a coil of roll-profiled feed-wire made of steel (11) through a twisting-die made of plastic (1). Also described is: a twisting-die made of plastic (1) that is suitable for twisting profiled feed-wire (11) made of steel; a method of forming a plastic twisting die (1) using an driven tap (31) in the form of a twisted rod (15); and a helically-shaped member (15) having lead measurements (X) along the length of the helical thread that vary less than pitch measurements (Y) along the lengths of the helical threads.

A twisted helically-shaped member (15) in the form of a twisted tie, twisted fastener, twisted wire or twisted rod; said twisted helically-shaped member (15) having an axial core (12) and a plurality of helical threads (13H) extending along the axial core (12); and wherein a variation in lead measurements along the length of at least one helical thread (13H), is less than a variation in pitch measurements along the lengths of the helical threads (13H); wherein the axial core (12) has a transverse cross-sectional area comprising two-fifths or less of the transverse circumscribed cross-sectional area of the helical threads (13H).

A high-speed and high-quality nail-making system is disclosed. The system includes an inner wheel, which is rotated by a motor and a power transmission unit and which clamps and transfers steel wire pieces, an outer wheel, which is passively rotated and which is eccentrically disposed outside the inner wheel so as to press the steel wire pieces at a punching portion, at which the outer wheel is positioned closest to the inner wheel, inner and outer wheel dies, which are mounted on the inner wheel and the outer wheel and which are positioned closest to each other at the punching portion so as to grip the steel wire pieces, a punching unit, which is rotated together with the inner wheel and which punches front ends of the steel wire pieces to form nail heads, and an ejector disposed between the inner wheel and the outer wheel so as to discharge the finished nail.

Embodiments described herein provide a fastening device such as a nail or staple having at least one projection each extending away from the body at an angle and away from a tip of the body. For example, in the case of a nail, there can be two or more projections extending from the elongated member of the nail each at a substantially equal distance from the head and/or along the length of the elongated member each spaced at substantially equal distances apart. In the case of a staple, there can be at least one projection connected to the interior surface of a first leg of the staple, that surface being substantially opposite to an interior surface of a second leg of the staple. The tip can be sharp or not sharp. The projections can be connected to exterior surfaces of the staple's legs.
