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, 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.

A blade for a measuring tape device may include a first end configured to extend from a housing of the measuring tape device through an aperture, a second end configured to be wound on a reel assembly within the housing, and a first cupped portion having a first amount of cupping over a selected portion of a longitudinal length of the blade. The first cupped portion may be defined by a curved portion extending from an apex of the curved portion toward lateral edges of the blade, and wings extending from each of the lateral edges toward the curved portion on each side of the apex. The curved portion includes a first radius proximate to the apex of the curved portion, and a second radius at a point spaced apart from the apex on both sides of the apex, the second radius being different than the first radius.

The present invention relates to a mobile blasting apparatus for injecting abrasives onto the surface of an article to be processed, the mobile blasting apparatus comprising: a body; a frame structure including a first rail extending along a first direction; a first moving device which can move the position of the body reciprocally along the first rail; and an injection device coupled to the body so as to inject the abrasives. According to the present invention, all processes can be automated without workers' manual work, so that the overall working time is reduced even when an article to be processed is large in length or volume, and there is no concern that work over a long time, strong jets of abrasives, and noxious dust would cause harm to worker health.

A rotary wheel cleaning device is composed of a feeding station, a cleaning station, a blowing station and a discharging station. The feeding station completes positioning, jacking and clamping of a wheel; the cleaning station completes cleaning of the wheel; the blowing station completes blowing of the wheel; and the discharging station transfers the cleaned wheel. The device can continuously perform the operations of feeding, cleaning, blowing and discharging of a wheel to be cleaned by rotating the wheel into different angular position on a station turntable, thereby automatic continuous production is achieved.

Provided are a method and a device for descaling that make it possible to effectively remove oxide scale from the surface of a metal wire. The descaling includes spraying the surface of a metal wire (W) with a mixture (9) of water and hard particles from a plurality of nozzles (8). The plurality of nozzles (8) include a plurality of self-cleaning nozzles that spray at a spray angle () of 90 or smaller with respect to the metal wire (W). The spray angle () is the angle formed by the central axis (X) of the spraying and a vector (Vt) indicating a conveyance direction that originates at the intersection (P) of the central axis (X) and the metal wire surface.
