Abstract:
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.
