A gyratory finishing machine, of the type in which the finishing units gyrate about a common center and advantageously rotate about their own axis, is provided with loading and unloading means for loading and unloading selected finishing chambers without stopping the gyration of the other finishing chambers. This is generally accomplished through a null-point producing means for establishing a null-point relation between the selected finishing chamber and the loading and unloading means. The null-point can be established by bringing the selected finishing chamber to said common center, or by causing said loading and unloading means to gyrate in unison with the gyration of the selected finishing chamber. The loading and unloading can be effected while the selected finishing chamber is at the common center or by transferring the selected finishing chamber from the null-point to a remote loading station.
