Alpilegno, a Leader in the sector of high-quality, high-performance windows and doors, performs sanding operations followed by profiling operations in its Val di Ledro (TN) manufacturing unit.
Loris Cellana, an entrepreneur with long-standing experience in this sector, recalls how he evaluated machinery and system suppliers for over two years to find one that could guarantee a cutting-edge finished product: “In the end I chose Biesse”. The core of the new manufacturing line is a Uniwin machine, combined with a modern 5-axis Rover C that produces doors. “I think that Uniwin is already a good profiling machine in itself, but what was equally important to me was its interaction with other line components, such as the planer, the sanding machine and the press, and the material flow between the various machines”.
Components are custom-cut and stored in a loading device by Biesse’s automation programme that feeds the automatic planer. A conveyor belt moves the work pieces from the planer to the sanding machine, a Viet 334 Bottom also supplied by Biesse. From there, the components are sent to the Uniwin’s loader, from which they are picked to be fully processed. 72, 80, 92 and 104 mm thicknesses in wood and wood-aluminium are processed. The magazines house up to 98 tools that are always available. Such tools can be changed in real time during machine operation thanks to a chain-operated tool-changer.
I like Biesse’s solution: it is compact, the machines are efficient and, since they all come from the same supplier, it is easy to learn how to operate them.

“Assembly precision enables us to avoid having to remove glue residues from the frame”, explains Cellana: “in this way, surface calibration and sanding must be arranged the one after the other, to go to the pressing stage immediately after profiling”. Moreover, individual components are not painted before they are pressed, as it is customary. As a matter of fact, Cellana paints the entire frame.
The compact production line occupies a footprint of only 15x15 metres; components are always handled forward and backward from the planing to the profiling machine, leaving enough space also for a walkway. “I like Biesse’s solution: it is compact, the machines are efficient and, since they all come from the same supplier, it is easy to learn how to operate them”, explains a visibly satisfied Cellana.
