Abstract (en)

Method and apparatus for vibrating mass treatment of metal surfaces, comprising finishing means forming, together with the workpieces being treated, an incoherent mass which is caused to advance along a preset path (A) at the end whereof the separation of the treated workpieces from the finishing means is effected and the finishing means are cycled back. To control the duration of the treatment cycle, a controlled portion of the finishing means is introduced into the path (A) at one or more locations (25) in a zone downstream at a distance from the beginning zone (8) of the cycle to form a weir counterhead and slow down the advancing incoherent mass upstream.
