750A Sincro 4.0 Industrial

The evolution of the smallest of the Sincro series lines continues.

Paolo Chierici

We honestly thought we had exhausted the subject in March of 1999 when, in Perini journal n. 14, we spoke of the then-newborn Sincro 4.0. The design engineers had exercised their skills and ingenuity by building a complete line and containing it within compact dimensions, just like the market demanded. Capable of productions comparable to those of machinery belonging to superior categories with the reliability, flexibility and efficiency typical of Sincro lines, this small machine seemed to have occupied its space in the catalogue of the latest generation rewinders. Back then, we had used expressions like "closing the loop" and "having attained an objective". Evidently, we were wrong.

From the technical department of the Alfa Research and Development Division come fresh new projects and before the shiny clean workshop floor has a chance to gather any dust, a machine is assembled and ready for checkouts. Thanks to the creative effort of the design engineers, who don't like to say the word "finished" about any project, after two years we find ourselves having to once again adopt the overused term "novelty", inseparably connecting it to the smallest machine of the Sincro range. But this time we are justified in doing so. Let's see why.

THE MODEL 750A IS AN AUTOMATIC REWINDER FOR THE CONTINUOUS WINDING OF INDUSTRIAL ROLLS WITH CARDBOARD CORES. It represents the industrial version of the Sincro 4.0, of which it retains the layout and the many technical devices, the first of which is the Perini three-roll surface winding system, together with the Sincro transfer mechanism, that unites precision operation with simplicity of construction and allows snap-off of the ply in correspondence of the chosen perforation, whatever it may be. With the Sincro 4.0 Industrial, it is possible to produce rolls at the maximum speed of 400 mpm with manually adjustable perforation lengths and external diameters that can vary from 100 mm to 450 mm, wound on cores having a diameter included between 30 mm and 80 mm. The tissue logs exit the rewinder and are ready to be sent to the subsequent cutting and packaging phases.

The general rationality and cleanness of the design, and therefore the easy adjustments which are reduced to a minimum, as well the extremely short downtimes, are concretely transmitted at the production phase, fundamental aspect for those converters interested in this type of product. The impulses that have induced the design engineers to develop this line come directly from the market, which for some time has been requesting a machine that could unite simplicity of operation and excellent quality productions with moderate initial investments and low installation and management costs. The basic philosophy is the same as the original Sincro 4.0 project: succeeding in compacting a line to an extremely reduced size without sacrificing the fundamental functions requested. And this machine is the result. It inherits the essential structure of the Sincro 4.0 and most of its fundamental elements while, in the winding section, it adopts parts designed especially for the specific production of industrial rolls.

The first sample of the Sincro 4.0 Industrial was presented at the Open House that was dedicated mainly to the XXL. Even though at first glance the workshop was set up to show that the object of greatest interest was none other than the largest line in the world, even the small 750A received its deserved attention. Now, all that's left to do is await the authoritative response of those converters who have decided to purchase it, to verify, with time, the undeniable qualities of this line. But we all know that entrepreneurs hardly ever gamble... unless they are sure to win.
