Device for rounding corners of panels

Device for rounding corners of panels made of chipboard, MDF or the like, comprising feeding means mounted on a support structure (2) and able to convey with a continuous movement a panel between an entrance way and an exit way, and a mobile carriage (4) mounted guidably on the support structure and moved by a first motor (7) so as to be displaced parallel to the panel and in synchronism with the latter in a direction of advancing movement. On the mobile carriage a milling unit (3) is rotatably mounted about a shaft (12) with an axis (X) transverse to the direction of advancing movement (Y) of the carriage and the panel. The milling unit is provided with a second motor (13) having, keyed on its rotating shaft, a milling tool and is actuated so as to rotate by a third motor (15) integral with the carriage (4) and electrically coupled to the first motor (7) so as to synchronize in accordance with predefined operating steps the rotation and the displacement of the milling unit (3).
