Abstract:
1. An automatic machine for grinding the borders of substantially flat glass panes, comprising a machine body and at least one machining head, which is adapted to make contact with the borders of said pane and can move along the perimeter of said pane, said at least one machining head comprising a tool body that is movable substantially transversely to the plane of said pane, said tool body comprising an abrasive tool for performing said grinding and at least one feeler element, which has substantially the same profile as said abrasive tool and is arranged upstream of the machining area of said abrasive tool with respect to the direction of relative advancement of said tool with respect to said pane, so as to make contact with the border of said pane being machined before said abrasive tool, said tool body further comprising sensors suitable to detect a relative movement between said feeler element and said abrasive tool caused by a local misalignment between the border of the pane being machined and said abrasive tool, said machine further comprising a controller for receiving feedback signals from said sensors and actuation means that are operated by said controller in response to said feedback signals, in order to regulate the mutual position of said abrasive tool and of the border of said pane being machined.
