A reactor plate assembly for a fastener dispensing device includes a metal reactor plate mounted onto the distal end of a fixed support arm for the device, the reactor plate including a flattened top surface shaped to define a pair of elliptical, needle-receiving holes. The reactor plate assembly additionally includes a brush anvil removably secured to the underside of the support arm. The brush anvil includes four separate bristle clusters that are retained within associated bores in a block, with a first pair of bristle clusters projecting into one needle-receiving hole and a second pair of bristle clusters projecting into the other needle-receiving hole. Each bristle cluster includes a group of individual nylon bristles, the free ends of the bristles lying flush with the top surface of the reactor plate to provide a planar support surface which can be penetrated by the needles of the device during the dispensing process.

A system for dispensing a fastener from a reel of fastener stock to couple together two or more objects comprises a module for dispensing the plastic fastener and a mounting stand on which the module is mounted. The mounting stand includes a vertical leg, a first horizontal leg, a second horizontal leg and a pair of spaced apart, parallel shafts extending between the first and second horizontal legs. A linear ball bearing is slidably mounted onto each of the shafts. A bearing mount is fixedly mounted onto each of the linear ball bearings. A bracket is fixedly mounted onto the pair of bearing mounts. The module is mounted onto the bracket and is capable of linear displacement. Upper and lower adjustable collars are fixed in place on the pair of shafts to limit the range of the linear displacement of the module.

Continuously connected fastener stock and a method of making same. In one embodiment, the method involves providing a rotating molding wheel, the wheel being provided with a peripheral impression comprising a pair of peripherally-extending side members interconnected by a plurality of cross-links. Molten plastic is extruded into the peripheral impression of the wheel, with a layer of controlled film overlying the peripheral impression. The molten plastic is then allowed to solidify. A knife in substantially elliptical contact with the peripheral impression is then used to skive excess plastic from the rotating molding wheel. The knife is provided with a pair of cut-out portions along its bottom edge, each cut-out portion being aligned with one of the peripherally-extending side members so as to augment the transverse cross-sectional size thereof. The continuously connected fastener stock thus formed is then removed from the rotating molding wheel.

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.

Needle for use in a plastic fastener dispensing tool. In one embodiment, the needle is a two-piece structure including a stem and a base. The stem, which is made from stamped and rolled metal, has a front portion and a rear portion. The front portion is generally cylindrical in shape and has a longitudinal bore adapted to receive a cross-bar, a longitudinal slot adapted to permit a filament to pass therethrough while a cross-bar is seated in the bore, and a tip adapted for insertion into an article. The rear portion of the stem is provided with an asymmetric V-shaped cutting notch along its rear edge for use in severing the severable connector between a fastener and its runner bar. The notch has an internal angle of approximately 110° and a width of approximately 0.050-0.055 inch. The vertex of the notch is positioned at the centerline of the bore. The base, which is made of molded plastic, is mounted onto the rear portion of the stem. The base includes a longitudinal bore, a longitudinal slot, a lateral slot and a recess. The bore of the base is aligned with the bore of the stem and is similarly adapted to receive the cross-bar of a plastic fastener. The slot of the base is aligned with the slot of the stem and is similarly adapted to permit the flexible filament of a fastener to pass therethrough while the cross-bar is seated in the bore. The lateral slot is used to permit a cross-bar to be loaded into the base from the side of the base. The recess is adapted to accommodate a needle locking shaft of a plastic fastener dispensing tool. The base is also provided with a cutout at the rear end thereof that is in alignment with the notch of the stem and which serves to prevent the base from interfering with the operation of the notch.
摘要:
A device for use in detecting the unauthorized removal of an article of commerce from a store or other business establishment. The device comprises a fastener of the type constructed for use in attaching a tag to the article of commerce. The fastener includes an elongated unitary member having a first end, a second end and a flexible filament, the flexible filament interconnecting the first end and the second end. The first end is shaped to define a cross-bar insertable through an article of commerce. The second end is sized and shaped to prevent the flexible filament from being pulled completely through the article of commerce. The device further comprises an electronic article surveillance (EAS) tag which is incorporated into the fastener. The EAS tag can be commonly used tag such as an electromagnetic tag or a radio frequency tag and can be located in either the first end, the second end or in the flexible filament of the fastener. The device can be manufactured through a continuous molding process.
摘要:
A plastic fastener which may be inserted into a body of meat for tagging purposes comprises an elongated unitary plastic member shaped to include a transverse bar, a paddle, and a flexible filament interconnecting the transverse tag and paddle. The portion of the transverse bar constituting the trailing end thereof when the transverse bar is inserted into the meat is made smaller than normal so as to minimize the likelihood of the transverse bar severing from the filament when the fastener is withdrawn from the body of the meat.
摘要:
Double "T" bar fasteners are dispensed through spaced needles which extend from different portions of the attacher housing. To attach a button, the needles are inserted through the thread holes of the button as it is held adjacent to the material to which it is to be attached. The housing portions are resiliently connected so that the portions can be moved relative to each other to vary the needle spacing and thus accommodate buttons with different hole spacing. The portions are biased to return to the original position. The portions may be halves of the housing connected by a living hinge. Internal compartments within each housing half enclose portions of fastener feed mechanism. The compartments are accessible when the housing is open to permit insertion of the parts and close when the housing halves snap-fit together. Each feed mechanism portion includes a spring loaded pawl with a tooth which normally engages an index wheel. The pawls are manually caused to travel along a path defined by oval guide tracks in the housing wall to cause the index wheels to simultaneously rotate and feed the fasteners.
