摘要:
Fastener stock (111) and a device (211) for dispensing a plastic fastener (118) from a supply of ladder-type fastener stock (111) includes a pair of separate modules that are independently pneumatically powered by a common air source. Each module is adapted to receive and index a corresponding side rail (113, 115) of the fastener stock, separate a cross-bar (119, 121) therefrom and eject the separated crossbar out through a sharpened needle (243). As a feature of the invention, the pair of modules ejects the cross-bars of the dispensed fastener in an offset relationship to minimize fastener stress. As another feature of the invention, the pair of modules is independently slidably coupled to a common mounting plate (215). In this manner, the spacing and angular orientation between the modules are adjustable. As another feature of the invention, the feed mechanism (247) includes a feed pawl (331) that selectively engages outwardly facing notches (125) formed in the side rail (113, 115) to ensure accurate alignment prior to the severing process.
摘要:
Procedure and device for application of a label to an article by means of an elastic fastening element. A label (44) is separated from a magazine (11) and conveyed via a guide (43, 86) towards a tube-shaped slit needle (19). The label is passed along the tip of the needle until the latter penetrates a pre-punched hole (100) in the label. Thereafter the label is withdrawn, threaded on the needle, partly into the magazine where it is retained. The tip of the needle is pressed through an article whereupon a retaining element is separated from a stem (1) and its head (3) is passed through the needle and thus also through the label and the article. When the needle is removed from the article the label remains hanging, anchored in the retaining element.
