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 shot treatment apparatus ejects shot material from a nozzle towards a workpiece, and has the nozzle; a nozzle moving mechanism; and a three-dimensional information obtaining sensor; a pattern storage portion storing a nozzle reference operation pattern when the workpiece is installed at a reference position and a reference pose within the treatment compartment; a model data storage portion storing workpiece three-dimensional model data; a position/pose displacement calculating portion comparing the position and pose information and reference position and pose data when the three-dimensional model data is at the reference position in the reference pose to calculate a displacement in a position and pose of the workpiece from the reference position and pose data; and a nozzle movement control portion correcting the pattern based on the displacement in the position and pose, and controlling the nozzle moving mechanism to move the nozzle based on the corrected pattern.

A high-pressure water jet sheet strip sand-blasting descaling cleaning device, a cleaning line and a system are disclosed. The cleaning device includes a cleaning box (7), a washing box (18) and descaling nozzles (6), the descaling nozzles (6) face to the same width direction of a sheet strip (5) and are arranged in a gradient along a conveying direction of the cleaning box (7) to jet covering the sheet strip (5). The system includes the cleaning device, an abrasive collecting box, a high-pressure water supply system, an abrasive supply-recovery-separation system and a sewage recycling treatment system. The nozzles are slantwise arranged in a gradient along the conveying direction, and the neighboring nozzles do not interfere with each other, and are used for cleaning successively, so that a cleaning process is stable and controllable. A high-pressure water jet sand-blasting cleaning technology is combined with a sheet strip conveying system, different specifications of sheet strips can be continuously and stably conveyed while surfaces thereof are cleaned by using the high-pressure water jet sand-blasting acid-free cleaning technology.

An engraving machine for engraving building material articles comprises a working plane on which, in use, at least one building material article rests, and defining a working area having a predetermined width, an engraving device facing the working plane and equipped with at least one reservoir for containing an abrasive particulate material, and an array of nozzles for delivering the abrasive particulate material configured for making a predetermined engraving path on the article, and moving means configured to determine a relative sliding between the working plane and the engraving device along a movement direction transverse to the predetermined width. The nozzles of the array are arranged in succession along a direction transverse to the movement direction to fully cover said predetermined width. A control unit is and configured to drive associated nozzles independently of each other.

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.

A shot processing apparatus in which a projection machine projects projection media onto a workpiece. The shot processing apparatus includes plural hanger transport devices and a control unit. The hanger transport devices are each, in a hanging state of a member on which a workpiece is set or a hanging state of a workpiece, capable of moving along a guide path inside the shot processing apparatus and capable of stopping. The hanger transport devices are also capable of providing self-identifying identification information. The control unit controls the hanger transport devices by outputting to each of the plural hanger transport devices a control signal appropriate to each of the hanger transport devices. This control is based on the identification information provided from each of the individual hanger transport devices and based on information related to each of the individual hanger transport devices stored in advance in association with the identification information.
