Abstract: A surface treating device includes a tubular blasting case member having a main open face and a sub-open face. A suction-adhering seal engages the blasting case to seal a space defined between the blasting case and the surface of the object being treated. Sand, water, or other abrasive material is ejected through a nozzle and the blasting case, toward the surface being treated. A flat belt or plate, which includes a nozzle opening, engages the sub-open face of the blasting case and covers the blasting case opening. A surface of the flat belt member is brought into sealing contact with a surface of the sub-open face due to a difference in pressure between an inside and an outside of a pressure reduction space such that the blasting case opening is completely covered and sealed while the flat belt member reciprocatingly moves along with the nozzle.

Abstract: A device capable of suction-adhering to and moving along the surface of an object includes a pressure reduction housing, a suction-adhering seal mounted on the pressure reduction housing and defining a pressure reduction space in cooperation with the pressure reduction housing and the surface of the object, and a vacuum generator for discharging a fluid from the pressure reduction space to the outside of the pressure reduction space. The device suction-adheres to the surface of the object by the pressure of an ambient fluid acting on the pressure reduction housing owing to the difference in fluid pressure between the inside and the outside of the pressure reduction space. The device is moved along the surface of the object by driven wheels which engage the surface.
