Abstract (en)
An apparatus (1) for smoothing a product (2), in particular a semi-finished ceramic product, comprises: an abrasive tool (3) in the form of an endless belt (4) which is trained around at least one pair of pulleys (5, 6), at least one of which is power-driven; the belt (4) has an active section (7) and at least one passive section (8); the active section (7) removes material from the product (2), while the passive section (8) receives a regenerating treatment that restores the abrasive capacity of the tool (3); drive means (20) acting on the belt (4) in such a way as to enable the belt (4) itself to move in the space surrounding the product (2); means (10) for spraying a liquid on the belt (4), which has liquid absorption properties, said means (10) being located in the vicinity of the belt (4) itself; and negative pressure means (9) associated with the passive section (8) of the belt (4) and operating in such a way as to extract the liquid and the materials retained by the belt (4) and removed from the product (2) during the smoothing process.
