Abstract
The present invention provides a lasting apparatus which is provided with an ejection device, which ejects blast media, and a recovery device, which sucks and recovers ejected and used blast media, on a traveling carriage, ejects the blast media to a surface to be treated by the ejection device while causing the traveling carriage to travel on the surface to be treated, and recovers the used blast media by the recovery device, and comprising: roughness measuring device that is provided at the traveling carriage and measures roughness of an uneven surface of the surface to be treated which is treated by ejection of the blast media; and control unit which performs a feedback control of an ejection amount of the blast media, ejection pressure, ejection speed, an ejection air amount, a suction air amount by the recovery device, and a speed of the traveling carriage so that the roughness which is measured by the roughness measuring device is within a range of predetermined roughness.
