A screw strip (1) is disclosed in which each screw (2) carries a washer (3) on its screw shank between the tip of the screw (2) and a plastic strip (1) carrying a plurality of screws. A screw driving apparatus (14), and method of use of the strip are also disclosed. The washers (3) and screw heads (4) are of relatively large diameter and adjacent washers (3) overlap each other. The power tools (13) used to install the screws include indexing means which advance successive screws into driving position, and retract the remaining screw strip rearwardly in order to avoid interference between the driving tool, the driven screw and adjacent washers. This configuration permits application of large head screws such as hexagonal head screws carrying large washers by power tool socket drivers and is particularly useful in sheet metal applications. The invention is applicable to any fastener with a threaded shank including bolts and screws.
Dans un bandeau à vis (1), chaque vis (2) porte une rondelle (3) placée sur sa tige entre l'extrémité de la vis (2) et ledit bandeau plastique (1) portant plusieurs vis. L'invention concerne aussi un appareil de vissage (14) et un procédé d'emploi du bandeau. Les rondelles (3) et têtes de vis (4) présentent un diamètre relativement important et des rondelles adjacentes (3) se chevauchent. Les outils à moteur (13) servant à serrer les vis comportent un dispositif de transfert qui fait avancer des vis successives en position de vissage et rétracte la partie restante du bandeau à vis vers l'arrière pour éviter tout heurt entre l'outil de vissage, la vis en cours de vissage et des rondelles adjacentes. Cette configuration permet d'utiliser des vis à grande tête, telles que des vis à têtes hexagonales porteuses de rondelles de grande dimension, avec des outils de vissage à douille, et elle est particulièrement utile en cas d'utilisation de tôles. Cette invention peut s'utiliser avec tout dispositif de fixation doté d'une tige filetée comportant des boulons et des vis.
