On plates of various types of material the "Fiorettatrici Ronzani" automatic grinders carry out the special overlapped and crossed circular buffing finish known as "fiorettatura" (flower embossing) or damascening or marbling. Another type of finish is also available, that of longitudinal strip grinding, which we call "a fasce" (in strips).

The "Fiorettatrici Ronzani" automatic grinders come in several different versions: with rollers ("A Rulli"), with feeder ("Ad Alimentatore"), combined ("Combi") and bench ("A Banco"). What mainly distinguishes them is how they move the plate: intermittently for the roller and feeder series, continuously for the combined series and without moving the plate for the bench series.

What all the versions have in common is the units of work. The working width ranges from 250 mm to 500 mm which, combining the versions and using or exclu-ding two or more units, gives a working width equal to plate standard measures of 1,000, 1,250, 1,500 and 2,000 mm. The centre distance of the spindles can be 60 or 50 mm on to which grinding wheels with a diameter of 60, 50 ,40 or 30 mm can be assembled.

The roller and combined series may be used to tenter the protective film, either at the same time as the flower embossing or to plastify the plates.
These versions come with a suction hood to clean the plate before the protec-tive film is applied.

Each machine can work with or without loaded and unloaded rollers and can be supplied with systems to move the plate, an automatic film cutter and suction and ventilation systems to clean and cool the plates.
