摘要:
An apparatus for winding round the stem of a button is disclosed wherein the drawbacks of the prior invention disclosed in U.S. Pat. No. 5,082,151 were settled. Namely, after drawing the winding thread from the bobbin and in the process of the winding operation, if the thread is recoiled and drawn, the tensile force of the thread decreases and during the winding operation maintaining high rotation speed, the thread is frequently cut off, which leads to the frequent interruption of the winding operation. It was very inefficient in the respect of operation and had impractical disadvantage. Such apparatus according to the present invention comprises a bobbin supporting means for interchangeably supporting the bobbin supplying the winding thread so as to rotate on its own axis to the unloosening direction of the thread in accordance with winding and drawing force of the thread, a thread winding means being fixedly mounted on the equal rotation axis to said bobbin supporting means for receiving from the bobbin the winding thread and winding it round the stem of the button while being rotated along with the bobbin in the equal direction and at the equal angular velocity, and a winding rotation means for rotatively mounting on the support the bobbin supporting means and the thread winding means being fixedly mounted on equal rotation axis and rotating it with driving force of a motor.

A self-contained button attachment assembly comprising a fastener dispensing tool (11) which includes a hollow, open-ended, unitary housing (19) generally cylindrical in shape. Four hollow, slotted needles (27-1 through 27-4) are fixedly mounted in the housing. Four ejector rods (35-1 through 35-4) are slidably mounted within the four needles, the four ejector rods being fixedly mounted at their respective top ends on a pusher plate (37) that is slidably mounted within the housing and is accessible through the open top end thereof. The assembly also comprises a conventional garment button (17) of the type having four transverse openings. The button is positioned and releasably retained within the housing by a circumferential lip (25). The assembly further comprises a pair of fasteners (15-1, 15-2), each fastener comprising a U-shaped flexible filament (43) and a pair of transverse feet (45-1, 45-2) which are disposed at opposite ends of the filament and extend perpendicularly to the plane of the filament.

Needle used in the rodless dispensing of plastic fasteners (P) which have a flexible filament (F) and a cross-bar (B) disposed at one end of the flexible filament (F). In one embodiment, the needle (11) comprises a solid elongated member (13) terminating at its front end in a tip (15) adapted to penetrate a desired article and a chamber (17) adapted to receive a cross-bar (B) of a plastic fasterner (P). The changer (17) includes a front end (21), a rear end (23), an open top (25) and an open bottom (27). The open top (25) is spaced rearwardly from the tip (15) and is appropriately sized and shaped to permit the insertion and removal of a cross-bar (B) into and from the chamber (17). Front end (21) is downwardly angled towards tip (15) to releasably engage top surface (TF) of the front end of cross-bar (B), and rear end (23) has a pair of walls intersecting in a V-shape to releasably engage bar (B) to prevent the cross-bar (B) from being pulled out of chamber (17) through open top (25) when low tension is applied to the flexible filament. When high tension is applied to the flexible filament, cross-bar (B) is caused to be pulled out of chamber (17) through open top (25).

A fastener attaching tool (51, 101) and fastener clip (11, 131) for use therewith. The fastener clip (11, 131) includes a plurality of fasteners (13, 133) which may be used, for example, in attaching a button to a garment or a piece of fabric, each fastener (13, 133) comprising a filament having a foot (17-1, 137) at one end. The fastener clip (11, 131) also comprises at least one runner bar (19-1, 141), each fastener (13, 133) being connected to the runner bar (19-1, 141) by a severable connector post (23-1, 143). The fastener attaching tool (51, 101) includes a pair of needles (57-1, 57-2). Each needle (57-1, 57-2) has a knife edge formed on its side which is adapted to sever a connector post (23-1, 143) from its associated runner bar (19-1, 141). The fastener attaching tool (51, 101) also includes an ejector mechanism (61) which is slidably mounted back and forth within the body of the fastener attaching tool (51-101) and is rearwardly biased by a spring (59). The ejector mechanism is manually operable from the rear of the body of the fastener attaching tool (51-101) and includes a pair of ejector rods (93-1, 93-2) which are slidable back and forth within the bores of the needles (57-1, 57-2).

摘要:
Bei einem Verfahren zum Umwickeln des Knopfstiels eines mit einem Nähfaden an ein Kleidungsstück angenähten Knopfes (6), bei welchem ein Umwicklungsfaden (1) aus einem elastomeren Kunststoff unter Zug auf das zwischen dem Knopf (6) und dem Kleidungsstück (10) aus dem Nähfaden gebildete Fadenbündel aufgewickelt wird, wird auf einfache Weise eine zuverlässige Befestigung des Umwicklungsfadenendes dadurch erreicht, daß der Umwicklungsfaden (1) nach dem Umwickeln des Fadenbündels (7) von dem Knopfstiel in etwa senkrechter Richtung zu dessen Achse mit einer bis über seine Streckgrenze hinaus erhöhten Zugkraft abgezogen wird, bevor er am Knopfstiel durchtrennt wird. Hierbei klemmt sich das über mehrere Windungen des Wickels reichende Fadenende aufgrund seines durch vollständige Dehnung stark reduzierten Durchmessers zwischen zuvor gelegten Windungen des Wickels fest ein. Es werden auch zwei Ausführungsformen einer zur Durchführung des Verfahrens bestimmten Vorrichtung beschrieben, die als kompaktes gut handhabbares Handgerät gestaltet ist.
摘要:
The present invention relates to a fastener and clip for use in attaching a button to a garment or a piece of fabric. In one embodiment, the fastener (11) comprises a U-shaped flexible filament (13) and a pair of transverse feet (15-1, 15-2) disposed at opposite ends of the U-shaped flexible filament (13). The U-shaped filament (13) is generally rectangular in cross section, has a substantially uniform width, a thickness greatest in its arcuate region and least towards the feet. The feet (15-1, 15-2) are sized and shaped to fit through a button hole and securely engage a garment. To minimize contact with a person's skin, the feet (15-1, 15-2) are preferably shorter that the transverse bars of existing button fasteners and comparable in overall size to a knot of thread conventionnally used to secure buttons. The feet (15-1, 15-2) have rounded ends (21-1/21-2, 23-1/23-2), a flat top surface (19-1, 19-2) and a contoured bottom surface (25-1, 25-2) to minimize irradiation of a person's skin.
