Estimating the term…
A needle particularly well-suited for use in the dispensing of plastic fasteners of the type comprising a filament having a cross-bar at a first end thereof; each of the cross-bar and the filament including a first flat side, the first flat sides of the cross-bar and the filament being coplanar. The needle includes a stem portion. The stem portion terminates in a tip at its front end and is shaped to define a longitudinal bore and a longitudinal slot. The longitudinal bore is shaped to receive the cross-bar, and the longitudinal slot is shaped to permit the filament to extend therethrough while the cross-bar is disposed within the longitudinal bore. The longitudinal bore has a first flat side, and the longitudinal slot has a first flat side, the first flat sides of the longitudinal bore and the longitudinal slot being coplanar. Preferably, the cross-bar and the filament collectively have a “d”-shaped cross-section, and the longitudinal bore and longitudinal slot of the needle collectively have a corresponding “d”-shaped cross-section. The stem portion is preferably made of a boron/nickel alloy and is preferably made using electroforming. A conventional needle base portion may be insert-molded onto the rear end of the stem portion to facilitate removable mounting of the stem portion in a fastener attaching tool.
A length of fastener stock, said length of fastener stock comprising a pair of continuous side members and a plurality of flexible cross-links interconnecting said continuous side members, said flexible cross-links being equidistantly-spaced apart at a pitch of about 0.18 inch;
A length of fastener stock, said length of fastener stock comprising a plurality of fasteners, each of said fasteners comprising a flexible filament and a cross-bar disposed at one end of said flexible filament, said cross-bar having a “B”-shape in transverse cross-section.
A length of fastener stock, said length of fastener stock comprising a pair of continuous side members and a plurality of flexible cross-links interconnecting said continuous side members, at least one of said continuous side members having a “B”-shape in transverse cross-section.
