Buffing Machines

Attiva

Through-feed band buffing machine

ATTIVA

Attiva is a band buffing machine for articles that require a cold processing and a high efficiency dust discharging. The machine is suitable to process vegetable tanned leathers, hot and cold greased leathers, stuccoed splits for automotive and reel material such as pvc, pu and similar. Clearly the Attiva is suitable to process split or grain articles such as corrected grain, suedes, nubuck etc.

The important feature of this machine is the inclination of the working bench to ease the exit of the leather from the buffing roller. The distance between the buffing point and the exit conveyor has been halved compared to a traditional buffing machine giving the advantage of having a leather perfectly laid out in the passage from the buffing machine to the dedusting one.

ATTIVA 4.0

Attiva 4.0 is a machine that has the interconnectivity among its main assets.

The machine is built to enable linking with the machine’s manufacturer for the monitoring of its functional parameters as well as for remote online assistance, and also to interact with the most advanced management programs used by the tanneries, in order to control all the productive phases involving its use. Furthermore, thanks to the installed software, Attiva can be programmed to inform the production department about special service interventions.
