ABSTRACT:
In a process for treating surfaces by means of a jet of liquid impinging on the latter at high velocity and with which, in particular, scouring or polishing solid particles, such as steel granules, corundum, sand, chalk or the like are admixed, the liquid jet is, after it has impinged on a surface to be treated, at least once returned to a surface to be treated for the purpose of exploiting the residual kinetic energy of the liquid. In a preferred form of the invention, the jet impinges on the surface at an angle of between 30.degree. and 80.degree. and is, after reflection from said surface, returned to the latter to impinge thereon at an angle of between 40.degree. and 90.degree.. In a particular embodiment of the invention, a sheet metal strip is guided along a loop and the jet impinges on a concave region within said loop.
