Abstract (en)
[origin: EP0488143A1] In the case of large round, oval or cornered objects, it is necessary for stability reasons during fire to create a further supporting point in the centre of the underside of the article in addition to the normal article foot. For this reason, a wave foot which can have the form of a web is integrally formed. Articles with this base configuration were hitherto ground by hand in a break-off machine. In contrast, the invention provides for the articles to be ground automatically by the articles, shown as oval plates 12, being placed with the corresponding work holders 14 on a rotary table 18 with six stations I, II, III, IV, V and VI. In station II, the wave foot 16 is ground with a grinding belt; and the plate foot 17 is ground in stations III, IV and V. For this purpose, the plates 12 or their work holders rotate eccentrically to the grinding tool at least in station II. <IMAGE>
