A tool for burring the surface of a material. The tool has two sets of oppositely facing toothed blades which are made to move towards each other when the tool is pressed against a surface. Each tooth planes a shallow groove into the surface which results in hook-like burrs or planings rising from each groove. Limiters on the blade stroke ensure that the raised burr is not severed. A spring returns the blades to their start position. The resulting surface therefore has a plurality of shallow, non-piercing stopped grooves with a like plurality of hook-like burrs. Such a modified surface provides increased surface area for electrochemical activity, and a mechanical grip to materials bonded thereto. The tool uses replaceable blade packs which snap into a permanent tool housing. The tool may be operated with a simple hammer blow or it may be rapidly driven into large or small areas of a surface by a manual and/or computer directed punch press.
Un outil d'ébarbage de surface d'un matériel, comprenant deux ensembles de lames dentées qui sont placées l'une en face de l'autre et conçues de manière à se rapprocher l'une contre l'autre lorsque l'outil est pressé contre une surface. Chaque lame creuse une rainure dans la surface et forme des bavures de découpage en forme de crochet dans chaque rainure. Des limiteurs sur le segment de la lame permettent de s'assurer que la lame relevée n'est pas disjointe. Un ressort ramène les lames dans leur position de départ. La surface ainsi obtenue affiche une pluralité de rainures creuses bien marquées et non percées dotées d'une pluralité de bavures de découpage ressemblant à des crochets. Ainsi modifiée, la surface offre une plus grande aire pour toute activité électrochimique et une adhérence mécanique au matériel qui y est lié. Cet outil utilise des ensembles de lames remplaçables qui s'engagent dans une boîte à outil permanente. L'outil peut être manipulé à l'aide d'un simple coup de marteau ou utilisé rapidement dans des petites ou grandes régions d'une surface à l'aide une presse mécanique manuelle ou gérée par ordinateur.
