Attiva 3200: higher quality, fewer steps in leather grinding
Bergi’s Attiva 3200 belt grinder is the latest-generation belt model for whole hides. Given the excellent results, in terms of finished product quality, obtained with the size 1800, the Bergi team decided to make the size 3200 to complete the range of belt grinders. As with the size 1800, this machine can boast a wide opening of both the upper protective casing and the leather introduction system; these two features facilitate machine maintenance and cleaning operations, making them safer and faster.
Very encouraging are the productivity and quality data surveyed and collected from user customers, who once they have found the right “recipe” for their processing confirm improvements in at least one of the two points. For example, some data show that for the same amount of leather processed, the Attiva 3200 model allows the same end result to be obtained with just one pass instead of the two made with a traditional model. Other data collected confirm the greater durability of the buffing paper with which a much higher number of skins can be processed than with a traditional model, in some cases even more than twice as many skins.
Another strong point, which is fundamental for a top-quality finished product, is the complete absence of vibrations when working. Attiva 3200 has also been used to process nubuck articles, obtaining excellent results as confirmation of its high-quality construction. Attiva 3200 is strongly recommended for articles that are more sensitive to sudden changes in temperature, as having the possibility of working at lower revs, compared to a traditional roller model, a more stable temperature is maintained in the working area, thanks also to the paper that dissipates more heat.
When analysing the belt working mode, it can be seen that, compared to the conventional buffing roller, the belt, due to its larger surface area, removes more material and discharges dust better, thus keeping it cleaner. A further advantage is that with the belt, the use of glue and base paper is no longer necessary, thus generating less waste over time.
A “hidden” feature of the Attiva 3200 is the patented automatic paper change release system; this optional accessory provides for the automatic release of the “cantilever” by means of a hydraulic system, thus eliminating the use of the compressed air gun. This accessory further facilitates paper change operations and reduces the possibility of paper snagging during insertion as the mechanical elements used in manual paper changing are removed.
