The invention concerns the use of working bodies of low density in vibratory abrasive finishing machines for the smoothing of articles of wood, particularly articles of furniture, between the undercoating and varnishing thereof. The working bodies have either the shape of angular resin-free wooden pins of a size of 4.times.4.times.30 mm and an average Shore A hardness of about 95.degree. to 100.degree. or a flat base opposite which there is a head surface corresponding to the shape of a spherical segment.

Smoothing of articles of wood in vibratory abrasive finishing machines

A vibratory container for flocculating waste water obtained upon vibratory abrasive finishing or the like, having an outlet and a feed connection which continues into a feed channel which extends into the inside of the container and is arranged in siphon-like manner with respect to the outlet pipe. For improved treatment of even chemically complex working liquids, the inside of the container is subdivided by partition walls into a plurality of chambers arranged one downstream of the other in the direction of flow. Connections are associated with the first two chambers arranged downstream of the feed channel within the initial region of the flow. The connections serve to introduce flocculation preparation chemicals, while a final connection is provided for the addition of the flocculating agent.
