Title
(EN) METHOD AND APPARATUS FOR PROVIDING A MEASURING TAPE WITH INCREASED CUPPING
(FR) PROCÉDÉ ET APPAREIL DE FOURNITURE D'UN RUBAN DE MESURE AYANT UN BOMBEMENT ACCRU
Abstract
(EN)
A method of producing a measuring tape may include providing a cupped blade with substantially uniform cupping over a longitudinal length of the cupped blade, applying a stress relief operation to a selected portion of only a convex side of the cupped blade to increase curvature of the cupped blade in the selected portion of the cupped blade where the stress relief operation includes bead blasting the selected portion via a dual nozzle shot peening assembly to define a combined bead blast area that is substantially centered with respect to a longitudinal centerline of the blade, and operably coupling the cupped blade to a reel assembly and providing the cupped blade and reel assembly within a housing to define the measuring tape device.
(FR)
L'invention concerne un procédé de fabrication d'un ruban de mesure pouvant comprendre les étapes consistant à fournir une lame bombée dotée d'un bombement sensiblement uniforme sur une longueur longitudinale de la lame bombée, à appliquer une opération de relâchement de contrainte sur une partie sélectionnée de seulement un côté convexe de la lame bombée afin d'augmenter la courbure de la lame bombée dans la partie sélectionnée de la lame bombée, l'opération de relâchement de contrainte comportant la projection de billes sur la partie sélectionnée par l'intermédiaire d'un ensemble de grenaillage à double buse afin de définir une zone de projection de billes mixte qui est sensiblement centrée par rapport à la ligne centrale longitudinale de la lame, et à accoupler fonctionnellement la lame bombée à un ensemble bobine et à installer l'ensemble lame bombée/bobine dans un boîtier afin de définir le dispositif de ruban de mesure.
