1. An apparatus for cutting at a bevel a piece presenting a reference surface with respect to which the plane of cut must be inclined, by the desired angle, characterized in that it comprises two parallel, vertical side elements (2, 3) in which are respectively provided two slots (4, 5) for guiding a saw blade, these two slots (4, 5) being parallel and opening in the edges (2a, 3a) of the side elements to define the plane of cut, means (11) for connecting the two parallel, vertical side elements (2, 3) to maintain them at a distance from each other along a common transverse axis (xy), a support (7, 8) mounted on each side element (2, 3) so as to be orientable about the transverse axis (xy) and presenting an upper bearing face, the two parallel, upper bearing face (7e, 8e) defining a bearing plane for the reference surface of the piece (1) to be cut, and means (9, 10) for blocking each support on the side element (2, 3) associated therewith so that its bearing face (7e, 8e) forms with the slot (4, 5) of the corresponding side element, an angle (a) equal to the desired angle of cut. |
