- Further according to the invention, said first friction element and said second friction element can be elongated elements.
- Preferably according to the invention, said first friction element and said second friction element are parallel.
- Advantageously according to the invention, said first friction element and said second friction element can each have a friction surface which has a substantially planar shape facing towards said detecting device.
- Conveniently according to the invention, said moving system can be configured to move, in use, said detecting device around said panel.
- Further according to the invention, said machine can comprise a second moving system to move, in use, said panel along an advancing direction in the space comprised between said first friction element and said second friction element.

- With reference to the accompanying drawings, the
numeral 1 denotes a machine for edging wooden panels, such as, for example, panels made of wooden chipboard. - In particular, the above-mentioned
machine 1 comprises a supportingsurface 2 which extends along a first axis X, above which there is aroller 3, that is to say, a series of rollers alongside each other. - The supporting
surface 2 and theroller 3 are positioned at a distance such that the interposing, between them, of a panel P arranged horizontally, that is, parallel to plane identified by the first axis X and by a second axis Y at right angles to said first axis X. - The
machine 1 also comprises a movement system to allow the feeding of the panel along the supportingsurface 2, along an advancing direction A parallel to the above-mentioned first axis X. - The
machine 1 comprises various operational systems and units positioned, in line, to the side of the supportingplane 2 and theroller 3, including a system for applying and gluing an edge element E flexible on a side face F of the panel P and, downstream of this, a system for end trimming the edge element comprising aworking device 4 which comprises, in turn, acutting tool 5 with a rotary operation about an axis of rotation Y1 parallel to the above-mentioned second axis Y and a copying device, that is to say, a device for detecting the exact profile of the panel P during the machining. - The
cutting tool 5 has a circular extension and a plurality ofshaped blades 7, positioned equidistant to each other around the periphery of the tool. - The blades of the above-mentioned plurality of
blades 7 are preferably four in number and arranged at 90° from each other. - More specifically, each
blade 7 is formed by an outerrectilinear section 7a, substantially parallel to said axis of rotation Y1, and a innercurved section 7b curved in a substantially radial direction. - In a position adjacent to each
blade 7 a groove 7' is formed, that is, a recess, to allow, in use, the discharge of machining waste during rotation of thecutting member 5. - The copying device comprises, on the other hand, a
rolling roller 8 mounted in an idle fashion on thecutting member 5 and acontact element 6 on which is fitted a spring acting such as to constantly push against the panel P, during machining, along the above-mentioned second axis Y. - The above-mentioned
cutting tool 5 is also movable with respect to thecontact element 6 along said second axis Y. - Both the
roller 8 and thecontact element 6 are coaxial to thecutting tool 5. - More specifically, the
roller 8 and thecontact element 6 carry out the function of determining the exact position of the panel P along, respectively, the third axis Z and the second axis Y. - In the
machine 1 there is also a dedicated movement system for moving theworking device 4 on a plane defined by the first axis X and by a third axis Z at right angles to the first axis X and to the second axis Y, independently from the movement of the panel P. - The same movement system just mentioned also allows the
working device 4 to be moved along the second axis towards or away from the panel P. - The
machine 1 comprises acontrol system 9 for limiting the rotation of the copying device during the various machining steps on the panel P. - The
control system 9 comprises, in a position above and below the zone for passage of the panel P, an upperrectilinear support element 10 and a lowerrectilinear support element 11, both oriented parallel to the first axis X of the panel P. - In particular, the above-mentioned
upper support element 10 is movable along the third axis Z, and thelower support element 11 is movable along said first axis X independently from the movement of theworking device 4 along the same axis. - The
machine 1 also comprises acontact element 12 for feeling, that is to say, detecting, the exact position of the panel P during predetermined working steps, such as to act as a spatial reference for operation of theworking device 4. - The
contact element 12 is positioned below the zone of passage of the panel P e movable along the first axis X integral with theupper support element 10 and thelower support element 11. - With respect the
upper support element 10 and thelower support element 11, the above-mentionedcontact element 12 is, on the other hand, movable, along the third axis Z, between a raised operating position and a lowered rest position. - In the
machine 1 there is also, downstream of the zone of action of theworking device 4, a final trimming system (not illustrated) for cutting, that is to say, removing, the portions of the edge element E protruding from the face of the panel P, remaining from the machining by means of the above-mentionedworking device 4. - More specifically, the final trimming system comprises two rotary cutting tools, with a fixed position, arranged facing each other at a reciprocal distance substantially equal to the height of the panel P, such that when the latter is passed through the space between said two rotary cutting tools, the protruding portions, upper and lower, of the edge element E are cut flush with the panel P.
- After inserting the unworked panel P, that is, free of edge elements on the respective sides, in the
machine 1, it is passed, by means of the above-mentioned movement system, in the zone of passage between the supportingsurface 2 and theoverlying roller 3 from a feed zone to a pickup zone. - Along the path from the feeding zone to the pickup zone the panel P is advanced along the advancing direction A at a constant speed and subjected, during the movement, to a series of successive machining operations.
- Initially, a flexible edge element E is applied, by gluing, on the side face F of the panel P facing the
machine 1 fed in a continuous fashion and cut to size after having been glued to the face. - In particular, the edge element E is dimensioned and cut such as to protrude both from the upper 13 and lower 14 faces and from the
front 15 and rear 16 faces (seefigures 21 and 22 ). - Subsequently, when the same panel P reaches the zone of action of the working
device 4, thecontact element 12 rises until making contact with thefront face 15 of the panel P. - Meanwhile, the
roller 8 of the copying device moves from a position resting on the upper support element 10 (seeFigure 11 ) downwards until coming into contact with theupper face 13 of the panel P moving thecontact element 6 in abutment with the edge element E, such as to allow the cuttingmember 5, already operational, to cut an upper part of the edge element E flush with the upper face 13 (seefigure 12 ). - The
work device 4 advances with respect to the panel P and then downwards (seeFigure 13 ) so that thecontact element 6 constantly adheres to the edge element E and theroller 8 first on theupper face 13 and them on thelower face 15, allowing, in this way, the cutting of the portion of the edge element E protruding from thefront face 15, flush with the latter. - During the cutting of the portion of the edge element E protruding from the
front face 15, thecontact element 12 moves to the lower rest position. - Once the front protruding part of the edge element E has been trimmed, the
work device 4 withdraws for a short section in the opposite direction to the advancing direction A in such a way as to cut a short side section of the portion of the edge element E protruding from thelower face 14 of the panel P (seeFigure 14 ), before lowering until theroller 8 is brought into contact with the underlying lower supporting element 11 (seeFigure 15 ). - The friction produced by the contact between the
lower support element 11 and theroller 8 determines the stopping of the rotation of the latter. - At this point, both the
work device 4 and thecontrol system 9 stop in position, stopping their transfer, until they are passed by the panel P constantly advancing along the advancing direction A (seeFigure 16 ). - After the
contact element 12 has raised until making contact with therear face 16 of the panel P, thework device 4 moves upwards moving theroller 8 into contact with thelower face 14 of the panel P allowing the cutting, by the cuttingmember 5, of a rear section of the portion of the edge element E protruding from the lower face 14 (seeFigure 17 ). - Once the panel P has completely passed the
work device 4, the latter rises upwards so that theroller 8 adheres to therear face 16 of the panel P and thecontact element 6 adheres to the edge element E (seeFigure 18 ), in such a way that the cuttingmember 5 cuts the portion of the edge element E protruding from therear face 16. - During the cutting of the above-mentioned portion of the edge element E protruding from the
front face 16, thecontact element 12 returns to the respective lower rest position. - After trimming the portion of the edge element E protruding from the
rear face 16, thework device 4 advances with respect to the panel P along the advancing direction A, keeping theroller 8 adhering to theupper face 13 and in this way allowing the cutting, by the cuttingmember 5, of a rear section of the portion of the edge element E protruding from the same upper face 13 (seeFigure 19 ). - At the end of the work cycle described above the
work device 4 until theroller 8 of the copying device makes contact with the overlying upper supporting element 10 (seefigure 20 ). - Also in this case, as mentioned above, the friction produced by the contact between the
lower support element 10 and theroller 8 determines the stopping of the rotation of thesame roller 8. - The braking function exerted by the upper supporting
element 10 and lower supportingelement 11 on theroller 8 of the copying device prevents the latter from reaching a rotation sped which is too high which could damage the surface of the upper 13 and lower 14 faces of the panel P. - Upon completion of the work cycle described above, the edge element E has a protruding extra upper portion and a protruding extra lower portion from, respectively, the
upper face 13 and thelower face 14 of the panel P (seefigure 20 ). - Following the machining by means of the
work device 4, the panel P is conveyed towards the above-mentioned final trimming system, where the upper and lower extra portions of the edge element E are removed. - The work cycle describe above, in which the
work device 4 rotates about the edge element E applied to the panel P, allows different appearances to be achieved on the edge element E according to the position assigned to thecutting tool 5, along the second axis Y, by the relative movement system. - If the cutting
member 5 is arranged in a withdrawn position along said second axis Y with respect to thecontact element 6 abutted with the edge element E, as shown inFigures 6 and 7 , only the outerrectilinear section 7a of theblades 7 is engaged on the edge element E determining the straight cutting flush with the upper 13,front 15, lower 14 and rear 16 faces of the panel P (seeFigures 23 and 24 ) during the various machining steps described above. - If, on the other hand, the cutting
member 5 is arranged in an advanced position along said second axis Y with respect to thecontact element 6 abutted with the edge element E, that is to say, closer to the panel P, as shown inFigures 8 and 9 , both the innercurved section 7b and a part of the outerrectilinear section 7a of theblades 7 are engaged on the edge element E determining a rounded cut, that is to say, bevelled, as shown inFigures 25 and 26 . - The work cycle described above can, clearly, be repeated according to the number of faces of the panel P to be edged, changing the orientation of the panel P at each work cycle.
- As may be seen from the above description, the control system described allows the machining operations planned on the edge of the panel to be performed effectively without the risk of damaging it.
- This invention is described by way of example only, without limiting the scope of application, according to its preferred embodiments, but it shall be understood that the invention may be modified and/or adapted by experts in the field without thereby departing from the scope of the inventive concept, as defined in the claims herein.
