DEVICE FOR ROUNDING OFF THE LONGITUDINAL EDGES OF HEAVY CLAY PRODUCTS DURING THE PRODUCTION PHASE PARTICULARLY, BUT NOT EXCLUSIVELY, FOR EXTRUDED BENT TILES

摘要

Device for rounding off the longitudinal edges of heavy clay products during the production phase, particularly, but not exclusively, for extruded bent tiles. It includes profiling tools having a curved contact surface, which is a replica of the rounded edge surface that has to be obtained on the final product and also a flat or curved cutting surface that intersects the first one creating a curved cutting edge. Such tools also have a grove, almost parallel to the cutting wire, by which the cutting wire passes inside. To keep the correct working position, the tools lean against the processed element, with a certain adjustable pressure, by means of a force-controlled driving system. The driving system can either be a fluid powered or mechanic or electronic system.
