The edgebanding device normally comprises two
rollers arranged in succession to each other in the second direction, and between which one, for example, is a glueing roller adapted to apply glue on the second lateral face of the panel and/or on the finishing edge and the other is a pressing roller adapted to press the finishing edge onto said second lateral face.

With reference to figures 1 and 2, numeral 1 indicates, as a whole, a machine for processing wood panels 2 and alike, each of which has a substantially rectangular shape, and comprises two major faces 3 which are parallel to each other and a lateral contour 4,
which extends between the two faces 3, is substantially- perpendicular to the faces 3, and comprises, in this case, two minor faces 5a, 5b which are parallel to each other and two minor faces 6a, 6b which are parallel to each other and perpendicular to the faces 5a, 5b.
Machine 1 comprises a substantially rectangular- shaped base 7, which is upwardly limited by a flat wall 8 defining a substantially horizontal support plane P for at least one panel 2, and comprises two support blocks 7a, 7b which are separated from each other by a cavity 9.
Machine 1 further comprises a fixed portal 10 comprising, in turn, two vertical uprights 11, which are arranged on the opposite sides of base 7 in a horizontal direction 12, extend in a vertical direction 13 transversal to direction 12, and carry connected to the free ends thereof a horizontal crosspiece 14, which extends above base 7 parallel to the direction 12 itself .
Crosspiece 14 supports an operating head 15 of the known type, which is coupled in a known manner to crosspiece 14 to perform, along the crosspiece 14 itself, rectilinear movements in direction 12, and is provided, in this case, with at least an electro-spindle 16 and at least a drilling device 17 coupled in a known manner to head 15 in order to perform, with respect to
head 15 itself, rectilinear movements in direction 13.
Electro-spindle 16 is shaped to receive and hold known tools and/or assemblies (not shown) adapted to carry out a machining by stock removal of the panels 2 (e.g. milling and/or cutting and/or finishing machining processes of an edge applied on contour 4 of the panels 2) , while device 17 is provided with a plurality of drill bits (not shown) mounted to rotate about respective longitudinal axes parallel to direction 12 and/or direction 13 and/or to a horizontal direction 18 orthogonal to directions 12 and 13.
Crosspiece 14 further supports a plurality of pressing members 19, which are distributed along crosspiece 14 in direction 12 in order to press panel 2 against plane P, and each comprises a respective pressing roller 20 pivotally mounted on a support arm 21 connected to crosspiece 14 by means of interposing a known damper device (not shown) .
Machine 1 further comprises a grip and transport device 22, which moves panel 2 along plane P and through portal 10 in both senses of direction 18, and has a slide 23, which extends above base 7 in direction 12, and is coupled in a known manner to base 7 in order to perform, with respect to said base 7, rectilinear movements in direction 18.

which are fixed along slide 23, facing portal 10, and each comprises a respective lower jaw and a respective upper jaw which are mobile with respect to one another in direction 13 between a locking position and a releasing position of panel 2.
According to a variation (not shown) , the vices 24 are mobile with respect to each other along slide 23 in direction 12.
According to a further variation (not shown) , the vices 24 are coupled in a known manner to slide 23 in order to perform, with respect to slide 23, rectilinear movements in direction 18 and be positioned irrespective of one another depending on the shape of the panels 2.
Machine 1 further comprises a edgebanding assembly 25 for edgebanding panel 2 with a finishing edge 26. Assembly 25 comprises a support and unwinding unit 27 of the known type, which is mounted next to base 7 in correspondence of the portal 10, and comprises, in turn, a support 28 for a reel (not shown) of edge 26 and an unwinding device 29 for unwinding edge 26 from reel itself (not shown) .
Edge 26 is fed from device 29 to an edgebanding head 30, which is coupled in a known manner with crosspiece 14 in order to perform, with respect to crosspiece 14, rectilinear movements in direction 12, and supports a vertical slide 31 coupled in a known
manner with head 30 in order to perform, with respect to said head 30, rectilinear movements in direction 13.
Head 30 has an edgebanding device 32 comprising a support plate 33 which is pivotally coupled to slide 31 in order to rotate, with respect to said slide 31, about an axis of rotation (not shown) parallel to direction 13.
According to what is shown in figures 1 and 3, plate 33 supports a tank 34 containing glue, a glueing roller 35 to transfer the glue taken from tank 34 onto contour 4 of panel 2, a return roller 36 to correctly position edge 26, and a pressing roller 37 adapted to press edge 26 against said contour 4.
Rollers 35, 36, and 37 are mounted to rotate, with respect to plate 33, about respective longitudinal axes (not shown) which are parallel to direction 13, and are moved by plate 33 about the aforementioned axis of rotation (not shown) between a first operating position (figure 3a), in which rollers 35 and 37 are aligned with each other in direction 12, and a second operating position (figure 3b) , in which rollers 35 and 37 are aligned with each other in direction 18.
According to some variations (not shown) :
the entire edgebanding assembly 25 is slidingly coupled to crosspiece 14; and
operating head 15 and edgebanding head 30 are
mounted on the opposite lateral faces of crosspiece 14;
Head 30 cooperates, in this case, with an auxiliary- pressing device 38 comprising a horizontal slide 39 coupled in a known way to crosspiece 14 in order to perform, with respect to crosspiece 14, rectilinear movements in direction 12, and two pressing rollers 40, which are mounted to rotate about respective longitudinal axes (not shown) parallel to direction 13, and are coupled in a known manner to slide 39 in order to perform, with respect to the slide 39 itself, rectilinear movements in direction 13, preferably but not necessarily irrespective of one another.
The rollers 40 are shaped to selectively control the bias exerted on edge 26, in particular, in correspondence of the upper and lower edges of the edge 26 itself. In this case, one of the rollers 40 comprises a cylindrical upper portion and a cylindrical lower portion with a smaller diameter than the upper portion, while the other roller 40 comprises a truncated conical upper portion and a cylindrical lower portion.
According to some variations (not shown) :
device 38 comprises a number of rollers 40 other than two ;
each roller 40 comprises a number of portions other than two ;
the portions have different shapes than those shown
in figure 1; and
device 38 comprises a pressing member having, for example, the shape of a rotating column having a polygonal cross-section in order to correctly press edge 26 on the lateral contour of panels 2 having one or more internal edges .
Operation of machine 1 will now be described with reference to figures 1, 2, and 3 and starting from an instant in which panel 2 is held by the clamps 24 of device 22 in correspondence of the face 5a thereof and in which device 32 is arranged in the first operating position thereof (figure 3a) .
Panel 2 is moved forward by device 22 through portal 10 in direction 18 so as to protrude with face 5b within cavity 9; if necessary, operating head 15 performs a machining by stock removal of face 5b, e.g. a milling machining, and/or a machining by stock removal of faces 3, e.g. a milling and/or drilling machining; the assembly defined by edgebanding head 30 and pressing device 38 is moved in direction 12 with a forward travel of unwinding of the edge 26 and with a return travel of edgebanding of the face 5b,· and edge 26, as soon as it is applied on face 5b, is finished by means of operating head 15, which is firstly lowered within cavity 9, and then moved in direction 12.
Once edgebanding of face 5b has been carried out,
device 32 is moved into the second operating position thereof (figure 3b) ; panel 2 is moved by device 22 in direction 18 in order to allow said device 32 to edgeband at least face 6a; and edge 26, as soon as it is applied on face 6a, is finished by means of operating head 15 combining the movements of panel 2 in direction 18 and the movements of head 15 in direction 12.
At this point, panel 2 is released by the clamps 24, is rotated by 180° on plane P, either manually or by means of an automatic device (e.g. a robot) , and is held by device 22 in correspondence of the face 5b in order to allow device 32 to edgeband at least face 5a.
Obviously, face 6b may be edgebanded both when panel 2 is locked within the clamps 24 in correspondence of the face 5a, and when panel 2 is locked within the clamps 24 in correspondence of the face 5b, and the edges 26 applied on faces 5a and 6b are also finished by means of operating head 15.
From what is described above, it therefore follows that at least faces 5b and 6a are edgebanded without ever releasing panel 2 from the clamps 24.
Figure 4 shows a panel 41 comprising two major faces 42 which are parallel to each other and a lateral contour 43, which extends between the two faces 42, is substantially perpendicular to the faces 42, and comprises, in this case, a flat minor face 44a, a minor
face 44b which is perpendicular and adjacent to face 44a, and a shaped face 44c extending between faces 44a and 44b.
In use, panel 41 is held by device 22 in correspondence of the face 44a, and is edgebanded in correspondence of the faces 44b and 44c without ever being released from the clamps 24. Panel 41 is therefore released from device 22, is rotated, is held by device 22 in correspondence of the face 44b, and is edgebanded in correspondence of the face 44a.
It is appropriate to specify that, when the clamps 24 are mobile in direction 18 with respect to slide 23, face 44a may also be edgebanded holding panel 2 in correspondence of the face 44c.
Finally, panel 41 is drilled by device 17 parallel to direction 13 so as to have, at the end of the operating cycle carried out by machine 1, the edges 26 and a plurality of holes 45 adapted to allow the assembly of the panel 41 itself.
The correct position of the holes 45 is determined by means of a detecting device (not shown), e.g. a photocell or a tracer, which is mobile along crosspiece 14 in direction 12, and is adapted, e.g. when panel 41 is locked within the clamps 24 with face 44a parallel to direction 18 and face 44b parallel to direction 12, to detect the position in direction 18 of an external face
26a of edge 26 applied on face 44b and/or the position in direction 12 of face 26a of edge 26 applied on face 44a.
Panel 41 and device 17 are therefore moved along base 7 in direction 18 and, respectively, along crosspiece 14 in direction 12 depending on a signal of the detecting device (not shown) to position the longitudinal axes of the drill bits (not shown) of device 17 at the correct distance D from the faces 26a. In this way, it is therefore possible to position the drill bits (not shown) of device 17 taking into account the effective thickness of the edges 26 and correctly carry out the drilling of panel 41.
Obviously, panel 2 may also be drilled by means of an operating sequence which is exactly the same as the one just described for panel 41, i.e. by detecting the exact position of the faces 26a of the edges 26 applied on contour 4 in directions 12 and/or 18 and consequently positioning the longitudinal axes of the drill bits (not shown) of device 17.
According to an operating method (not shown) , the panels 2, 41 can be obtained by cutting a sheet of wood of large dimensions by means of operating head 15.
Finally, according to some variations (not shown) , machine 1 comprises several auxiliary devices, such as, for example :
devices for inserting pins and/or hardware into the panels 2 ;
labelling devices;
control devices for controlling the machining carried out, such as, for example, video cameras; and marking devices to imprint instructions onto the panels 2 related, for example, to the correct orientation of the panels 2 in the clamps 24, to the subsequent mounting of the panels 2, and to the production of the panels 2 itself.
