Description
APPARATO DI BORDATURA EDGE BANDING APPARATUS
Il presente trovato concerne un apparato di bordatura. In particolare, la presente invenzione si riferisce ad un apparato e ad un processo per bordare specialmente un pannello di legno con un nastro di impiallacciatura. Nel dettaglio, la presente invenzione prevede di ottenere il fissaggio di un tale nastro per azione di attivazione termica effettuata mediante un raggio laser. The present invention relates to an edging apparatus. In particular, the present invention relates to an apparatus and a process for especially edging a wooden panel with a veneer tape. In detail, the present invention provides for obtaining the fixing of such a tape by means of thermal activation carried out by means of a laser beam.
La presente invenzione permette un efficace controllo della quantit? e dell?uniformit? del calore fornito alla zona di unione. The present invention allows an effective control of the quantity? and of the uniformity? of the heat supplied to the joining area.
Inoltre, rispetto agli apparati di bordatura con attivazione laser, permette di ridurre lo spessore del nastro da associare, in particolare del suo strato termo-attivable, consentendo di ottenere una finitura pi? pregiata dei prodotti bordati. Furthermore, compared to the laser-activated edging apparatuses, it allows to reduce the thickness of the tape to be associated, in particular of its thermo-activable layer, allowing to obtain a finer finish. high quality of edged products.
Pertanto la presente invenzione si colloca nel campo della bordatura di pannelli. Therefore the present invention is placed in the field of panel edging.
Oggigiorno, un apparato di bordatura tradizionale prevede di formare un bordo composto da uno strato di finitura ed uno strato di adesione. Nowadays, a traditional edging apparatus provides for forming an edge composed of a finishing layer and an adhesion layer.
Lo strato di adesione ? termo-attivabile per aderire al bordo da rifinire. The adhesion layer? thermo-activated to adhere to the edge to be finished.
L?attivazione termica dello strato di adesione, secondo tale processo tradizionale, ? attuata mediante un raggio laser. The thermal activation of the adhesion layer, according to this traditional process,? implemented by a laser beam.
Un dispositivo di emissione produce un fascio laser che intercetta la faccia del nastro dotata dello strato di adesione. An emission device produces a laser beam which intercepts the face of the tape equipped with the adhesion layer.
L?immagine del fascio sul nastro, ossia la zona di quest?ultimo che ? intercettata dal fascio, viene mossa per tutta l?altezza del nastro per attivare lo strato adesivo. The image of the beam on the tape, that is the area of the latter which? intercepted by the beam, it is moved along the entire height of the tape to activate the adhesive layer.
Una variante oggi nota prevede uno zoom ottico regolabile che consente di variare l?ampiezza dell?immagine del fascio laser sul bordo per adattare quest?ultima all?altezza del bordo stesso. A variant known today provides an adjustable optical zoom that allows you to vary the width of the image of the laser beam on the edge to adapt the latter to the height of the edge itself.
Un inconveniente di questi processi tradizionali ? quello di impiegare un laser ad elevata potenza che richiede un?efficace refrigerazione. A drawback of these traditional processes? that of using a high-power laser that requires effective refrigeration.
Un ulteriore inconveniente ? che tali processi forniscono al bordo un?elevata densit? di potenza che risulta non facilmente controllabile con conseguenti rischi di danneggiamento del bordo da incollare. An additional drawback? that such processes provide the edge with a? high density? of power which is not easily controlled with consequent risk of damage to the edge to be glued.
Inoltre, questo processo tradizionale risulta di applicazione limitata e non facilmente adattabile in caso di cambiamento del colore del bordo da incollare e quindi dell?assorbimento di radiazione a questo associato. Furthermore, this traditional process is of limited application and not easily adaptable in the event of a change in the color of the edge to be glued and therefore in the absorption of radiation associated with it.
Il problema alla base della presente invenzione ? quello di avere maggiore flessibilit? nell?operazione di bordatura. The problem underlying the present invention? to have greater flexibility? in the edging operation.
Compito principale del presente trovato consiste nel realizzare un apparato di bordatura che ponga soluzione a tale problema risolvendo i lamentati inconvenienti dei processi e apparati tradizionali sopra descritti. Nell?ambito di tale compito ? scopo del presente trovato proporre un apparato di bordatura che permetta di regolare facilmente la potenza termica per unire il bordo al pannello. The main aim of the present invention is to provide an edging apparatus which solves this problem by solving the aforementioned drawbacks of the traditional processes and apparatuses described above. As part of this task? purpose of the present invention to propose an edging apparatus which allows to easily adjust the thermal power to join the edge to the panel.
Un altro scopo del presente trovato consiste nel realizzare un apparato di bordatura che consenta di preriscaldare Another object of the present invention is to provide an edging apparatus which allows preheating
Ancora uno scopo del trovato consiste nel proporre un apparato di bordatura che permetta di applicare bordi di altezze diverse. Another object of the invention is to propose an edging apparatus which allows to apply edges of different heights.
Un ulteriore scopo del trovato consiste nel realizzare un apparato di bordatura che sia maggiormente affidabile rispetto a quelli tradizionali sopra descritti. A further object of the invention is to provide an edging apparatus which is more reliable than the traditional ones described above.
Ancora un altro scopo della presente invenzione ? quello di proporre un apparato di bordatura che richieda minore manutenzione e risulti pi? durevole in efficienza. Yet another object of the present invention? to propose an edging apparatus that requires less maintenance and is more? durable in efficiency.
Questo compito, nonch? questi ed altri scopi che meglio appariranno nel seguito sono raggiunti da un apparato di bordatura secondo la rivendicazione 1 allegata. This task, as well as? these and other objects which will become clearer in the following are achieved by an edging apparatus according to the attached claim 1.

Un apparato di bordatura secondo la presente invenzione consente di riscaldare gradualmente il nastro da unire permettendo un controllo della temperatura e della potenza termica ceduta al nastro molto migliore rispetto agli apparati laser tradizionali. An edging apparatus according to the present invention allows the strip to be joined to be gradually heated, allowing a much better control of the temperature and of the thermal power transferred to the strip with respect to traditional laser apparatuses.
Mediante l?apparato di bordatura secondo la presente invenzione, cos?, possono essere lavorati nastri di bordatura di un ampio spettro di colori e ottenere una efficace adesione degli stessi al bordo del pannello, riducendo contestualmente i rischi di danneggiare il nastro stesso. By means of the edging apparatus according to the present invention, it is thus possible to process edging tapes of a wide spectrum of colors and obtain an effective adhesion of the same to the edge of the panel, at the same time reducing the risk of damaging the tape itself.
L?apparato di bordatura secondo la presente invenzione in pratica consente di riscaldare il nastro da applicare al bordo del pannello in modo pi? uniforme rispetto alle soluzioni tradizionali e di utilizzare una minore potenza specifica cos? da evitare rischi di bruciature e danneggiamenti del nastro stesso. The edging apparatus according to the present invention in practice allows to heat the tape to be applied to the edge of the panel in a more effective way. uniform than traditional solutions and to use a lower specific power cos? to avoid the risk of burns and damage to the belt itself.

Secondo la presente invenzione, l?apparato di bordatura 10 presenta una particolare peculiarit? nel fatto di essere dotato di una pluralit? di emettitori 12, configurati in modo tale da emettere fasci laser orientati ad intercettare, in uso, una pluralit? di zone A della faccia termo-attivabile 100a del nastro 100; ove gli emettitori 12 sono disposti, rispetto al dispositivo pressore 11, in modo tale che in uso le zone A comprendono zone allineate lungo la direzione di avanzamento C. According to the present invention, the edging apparatus 10 has a particular peculiarity? in the fact of being endowed with a plurality? of emitters 12, configured in such a way as to emit laser beams aimed at intercepting, in use, a plurality of of zones A of the thermo-activable face 100a of the belt 100; where the emitters 12 are arranged, with respect to the pressure device 11, in such a way that in use the zones A comprise zones aligned along the direction of advance C.
In altre parole, in uso, gli emettitori 12 irradiano il nastro 100 in modo da intercettarlo in zone A che quantomeno si susseguono lungo la direzione di avanzamento C. In other words, in use, the emitters 12 irradiate the tape 100 so as to intercept it in zones A which at least follow one another along the direction of advance C.
Il nastro 100, in uso avanza lungo la direzione di avanzamento C cos? che le zone A scorrono su di esso e riscaldano gradualmente la faccia termo-attivabile 100a sulla quale incidono. The belt 100, in use, advances along the direction of advance C cos? that the zones A slide on it and gradually heat the thermo-activable face 100a on which they affect.
Infatti, ogni sezione del nastro, durante il suo moto relativo rispetto agli emettitori 12 viene intercettata in successione da una pluralit? di zone A cos? che in corrispondenza di ciascuna di queste il nastro riceve una predefinita quantit? di calore per irradiazione laser. In fact, each section of the tape, during its relative motion with respect to the emitters 12 is intercepted in succession by a plurality of elements. of zones A cos? that in correspondence of each of these the tape receives a predefined quantity? of heat by laser irradiation.
Tale riscaldamento risulta graduale e quindi facilmente controllabile e permette di evitare le densit? di potenza tipiche degli apparati di bordatura con laser tradizionali. This heating is gradual and therefore easily controllable and allows to avoid densities? of power typical of edgebanding devices with traditional lasers.
Preferibilmente gli emettitori 12 sono disposti in modo da formare una matrice tale da emettere fasci laser adatti ad intercettare, in uso, la faccia termoattivabile 100a del nastro 100 nelle zone A che preferibilmente comprendono zone allineate anche lungo almeno una traiettoria B che ? trasversale ad una direzione di avanzamento C. Preferably the emitters 12 are arranged so as to form a matrix such as to emit laser beams suitable for intercepting, in use, the heat-activated face 100a of the belt 100 in the zones A which preferably comprise zones also aligned along at least one trajectory B which? transversal to a direction of travel C.
In altre parole, gli emettitori 12 sono configurati per emettere una pluralit? di fasci laser orientati in modo da intercettare la faccia termo attivabile 100a del nastro 100, in una pluralit? di zone A che sono allineate sia longitudinalmente che trasversalmente alla direzione di avanzamento C del nastro 100. In other words, the emitters 12 are configured to emit a plurality of products. of laser beams oriented so as to intercept the thermo-activatable face 100a of the tape 100, in a plurality of of zones A which are aligned both longitudinally and transversely to the direction of advancement C of the belt 100.
Una configurazione particolarmente efficiente prevede che preferibilmente la traiettoria B sia rettilinea e perpendicolare alla direzione longitudinale C?. A particularly efficient configuration provides that the trajectory B is preferably rectilinear and perpendicular to the longitudinal direction C ?.
In questo modo, le zone A intercettate in uso dai fasci laser sul nastro 100 sono allineate anche lungo la traiettoria B che ? perpendicolare alla direzione longitudinale C? del nastro 100. In this way, the areas A intercepted in use by the laser beams on the belt 100 are also aligned along the trajectory B which? perpendicular to the longitudinal direction C? of tape 100.
In pratica, un apparato di bordatura 10 secondo la presente invenzione risulta pi? funzionalmente flessibile, rispetto agli apparati tradizionali, in quanto la distribuzione di potenza termica nelle zone A, reciprocamente affiancate longitudinalmente e trasversalmente, rispetto alla direzione di avanzamento C del nastro 100, permette di riscaldare quest?ultimo in modo pi? uniforme rispetto alle soluzioni tradizionali e di utilizzare una minore potenza specifica cos? da evitare rischi di bruciature e danneggiamenti del nastro. In practice, a beading apparatus 10 according to the present invention is more? functionally flexible, with respect to traditional apparatuses, since the distribution of thermal power in the zones A, mutually flanked longitudinally and transversely, with respect to the direction of advancement C of the belt 100, allows the latter to be heated more effectively. uniform than traditional solutions and to use a lower specific power cos? to avoid the risk of burns and damage to the belt.
In pratica, mediante un apparato di bordatura 10 secondo la presente invenzione, possono essere lavorati nastri di bordatura di un ampio spettro di colori e ottenere una efficace adesione degli stessi al bordo del pannello, riducendo contestualmente i rischi di danneggiare il nastro stesso. In practice, by means of an edging apparatus 10 according to the present invention, edging tapes of a wide spectrum of colors can be processed and obtain an effective adhesion of the same to the edge of the panel, at the same time reducing the risk of damaging the tape itself.
In una forma di attuazione della presente invenzione che permette una particolare flessibilit? e compattezza, l?apparato di bordatura 10 comprende una pluralit? di emettitori 12 -che possono essere inclusi in una testa multi-fascio 13- i quali sono preferibilmente organizzati in almeno due righe ed in almeno due colonne per irradiare le zone corrispondentemente organizzate in almeno due righe e almeno due colonne. In an embodiment of the present invention which allows a particular flexibility? and compactness, the edging apparatus 10 comprises a plurality of of emitters 12 - which can be included in a multi-beam head 13 - which are preferably organized in at least two rows and in at least two columns to irradiate the correspondingly organized areas in at least two rows and at least two columns.
Con particolare riferimento alle figure da 1 a 3a e 3b, in queste ? rappresentata, a titolo esemplificativo e non limitativo, una forma di attuazione della presente invenzione che presenta una soluzione preferita che costituisce un buon compromesso tra ingombri e capacit? di riscaldamento del nastro. With particular reference to figures 1 to 3a and 3b, in these? shown, by way of non-limiting example, an embodiment of the present invention which presents a preferred solution which constitutes a good compromise between overall dimensions and capacity. of heating tape.
Questa comprende 8 emettitori 12 disposti in due righe affiancate ciascuna comprendente 4 emettitori 12 cos? da essere adatti a formare, sulla faccia termoattivabile 100a, due righe affiancate, ciascuna di 4 seconde zone A, come ad esempio illustrato nelle figure 3a e 3b. This comprises 8 emitters 12 arranged in two rows side by side each comprising 4 emitters 12 cos? to be suitable for forming, on the heat-activated face 100a, two rows side by side, each of 4 second zones A, as illustrated for example in Figures 3a and 3b.
In una forma di attuazione che consente di ottenere una particolarmente elevata flessibilit? dell?apparato di bordatura 10 particolarmente elevata, vantaggiosamente l?apparato di bordatura 10 ? configurato in modo tale che gli emettitori 12 siano azionabili selettivamente, a tal fine l?apparato di bordatura 10 preferibilmente comprende un dispositivo di controllo 100 programmabile e/o azionabile per azionare selettivamente gli emettitori 12 per modulare l?estensione di un?area del nastro 100 che, in uso, ? intercettata dai raggi emessi dagli emettitori 12. In an embodiment which allows to obtain a particularly high flexibility? of the particularly high edging apparatus 10, advantageously the edging apparatus 10? configured in such a way that the emitters 12 are selectively operable, for this purpose the edging apparatus 10 preferably comprises a programmable and / or operable control device 100 to selectively operate the emitters 12 to modulate the extension of an area of the belt 100 which, in use,? intercepted by the rays emitted by the emitters 12.
In pratica, durante l?uso, il nastro viene riscaldato per azione successiva degli emettitori 12 che sono rivolti verso di esso. In practice, during use, the tape is heated by the successive action of the emitters 12 which are turned towards it.
Ad esempio, una forma di attuazione dell?apparato di bordatura 10 pu? essere del tipo di una bordatrice con avanzamento lineare del pannello 200 e del nastro 100, nel qual caso potr? avere emettitori 12 fissi, come per esempio illustrato in figura 1. For example, an embodiment of the edging apparatus 10 can be be of the type of an edge banding machine with linear advancement of the panel 200 and of the belt 100, in which case it can? have 12 fixed emitters, as for example illustrated in Figure 1.
Questi, per esempio, possono essere organizzati in due righe o colonne di 4 emettitori 12 ciascuna, come quelle illustrate nelle figure 1 e 2. These, for example, can be organized in two rows or columns of 4 emitters 12 each, like those illustrated in Figures 1 and 2.
In questo caso, il nastro 100 che avanza verso il dispositivo pressore 11 viene intercettato, in successione, prima dai fasci prodotti dalla prima colonna di emettitori 12 e poi dai fasci prodotti dalla seconda colonna di emettitori 12. In this case, the belt 100 which advances towards the pressure device 11 is intercepted, in succession, first by the beams produced by the first column of emitters 12 and then by the beams produced by the second column of emitters 12.
Un maggior numero di colonne di emettitori 12, eventualmente distanziate, permette di modulare in modo raffinato la densit? di potenza trasmessa alla faccia termo-attivabile 100a del nastro 100, per unit? di superficie di quest?ultima. A greater number of columns of emitters 12, possibly spaced apart, allows to modulate in a refined way the density? of power transmitted to the thermo-activatable face 100a of the belt 100, per unit? surface of the latter.
Nella forma di attuazione preferita della presente invenzione, illustrata nelle figure 4a e 4b, gli emettitori sono raggruppati in teste multi-fascio mobili, identificate con i riferimenti 13a, 13b e 13c. In the preferred embodiment of the present invention, illustrated in Figures 4a and 4b, the emitters are grouped in movable multi-beam heads, identified with the references 13a, 13b and 13c.
Tali teste multi-fascio sono attivabili in modo selettivo e sono mobili rispetto al nastro 100 in modo da modulare l?estensione di un tratto 100b del nastro 100, intercettato dai fasci generati dalle teste multifascio attive. These multi-bundle heads can be activated selectively and are movable with respect to the belt 100 so as to modulate the extension of a portion 100b of the belt 100, intercepted by the bundles generated by the active multi-beam heads.
In particolare, poi, quando il nastro ? intercettato dai fasci prodotti da una di queste teste, prima viene intercettato dai fasci prodotti dagli emettitori della prima colonna e poi dagli emettitori della seconda colonna. In particular, then, when the tape? intercepted by the beams produced by one of these heads, it is first intercepted by the beams produced by the emitters of the first column and then by the emitters of the second column.
In questo modo, il riscaldamento del nastro ? graduale, sostanzialmente a gradini e si evitano shock termici del nastro. In this way, the heating of the tape? gradual, substantially in steps and thermal shocks of the belt are avoided.
Peraltro, un?attivazione selettiva delle teste multifascio 13 e/o degli emettitori 12 delle stesse consente una fine ma semplice regolazione della potenza termica ceduta al nastro e, quindi, permette di adattare facilmente l?apparato di bordatura 10 all?applicazione di nastri di colori diversi o in generale dotati di differenti capacit? di assorbimento termico. Moreover, a selective activation of the multi-beam heads 13 and / or of the emitters 12 of the same allows a fine but simple adjustment of the thermal power transferred to the belt and, therefore, allows to easily adapt the edging apparatus 10 to the application of different colors or in general with different capacities? of thermal absorption.
Per ottenere una flessibilit? di impiego particolarmente elevata, le teste multi-fascio 13 vantaggiosamente comprendono mezzi di movimentazione 14 configurati per muovere gli emettitori 12. To get flexibility? of particularly high use, the multi-beam heads 13 advantageously comprise handling means 14 configured to move the emitters 12.
I mezzi di movimentazione 14 sono azionabili per, in uso, orientare gli emettitori 12 per regolare la posizione relativa delle zone A lungo l?altezza sul nastro 100 in modo da modulare la potenza specifica trasmessa al nastro 100 e/o modulare l?estensione di una parte di superficie del nastro 100 interessata dalle zone A. The handling means 14 can be operated to, in use, orient the emitters 12 to adjust the relative position of the zones A along the height on the belt 100 so as to modulate the specific power transmitted to the belt 100 and / or modulate the extension of a surface part of the belt 100 affected by the zones A.
Preferibilmente, i mezzi di movimentazione 14 sono configurati per muovere gli emettitori 12 in modo da orientarne la sezione di emissione del fascio laser secondo un movimento rotatorio D e/o un movimento traslatorio E in modo da poter spostare le zone A sul nastro 100 secondo una direzione parallela alla direzione longitudinale C? del nastro 100 e/o secondo una direzione lungo l?altezza del nastro D?, ossia perpendicolare alla direzione longitudinale C?, come ad esempio rappresentato in figura 2. Preferably, the movement means 14 are configured to move the emitters 12 so as to orient the emission section of the laser beam according to a rotary movement D and / or a translational movement E so as to be able to move the areas A on the belt 100 according to a direction parallel to the longitudinal direction C? of the belt 100 and / or according to a direction along the height of the belt D?, i.e. perpendicular to the longitudinal direction C?, as shown for example in Figure 2.
In questo modo ? regolabile l?estensione dell?area del nastro 100 investita dai raggi emessi dagli emettitori di una testa multi-fascio 13. So ? adjustable the extension of the area of the tape 100 hit by the rays emitted by the emitters of a multi-beam head 13.
Tale flessibilit? ? ulteriormente incrementata se l?apparato di bordatura 10 vantaggiosamente comprende mezzi di ri-posizionamento, non illustrati, configurati per muovere almeno una delle teste multi-fascio 13. Such flexibility? ? further increased if the edging apparatus 10 advantageously comprises re-positioning means, not illustrated, configured to move at least one of the multi-bundle heads 13.
I mezzi di ri-posizionamento sono azionabili per, in uso, orientare almeno una testa multi-fascio 13 per regolare, in uso, la posizione relativa delle zone A nella lunghezza del nastro 100 in modo da modulare la potenza specifica trasmessa al nastro 100 e/o per modulare l?estensione di una parte di superficie del nastro 100 interessata dalle zone A. The re-positioning means can be operated to, in use, orient at least one multi-beam head 13 to adjust, in use, the relative position of the zones A along the length of the belt 100 so as to modulate the specific power transmitted to the belt 100 and / or to modulate the extension of a part of the surface of the belt 100 affected by the zones A.
In tal modo ? possibile adattare facilmente l?area interessata dai fasci emessi dagli emettitori 12 e, quindi, adattare l?apparato di bordatura 10 ad applicare nastri di colorazione diversa o che avanzano a velocit? diversa o aventi assorbanza diversa o, ancora, aventi altezza diversa, come nei casi illustrati nelle figure 3a e 3b nelle quali si vedono due tratti 300 di nastro 100 di altezza diversa ove ? stata regolata l?orientazione degli emettitori 12 mediante l?azione dei mezzi di movimentazione 14 in modo da diradare le zone A lungo l?altezza del nastro, come in figura 3a, o compattarle, come in figura 3b. Thereby ? It is possible to easily adapt the area affected by the beams emitted by the emitters 12 and, therefore, to adapt the edging apparatus 10 to apply ribbons of different colors or which advance at high speed. different or having different absorbance or, again, having a different height, as in the cases illustrated in Figures 3a and 3b in which two sections 300 of tape 100 of different height are seen where? the orientation of the emitters 12 has been adjusted by means of the action of the handling means 14 so as to thin out the areas A along the height of the belt, as in figure 3a, or compact them, as in figure 3b.
Un apparato di bordatura 10 secondo la presente invenzione consente inoltre di adattare facilmente la velocit? relativa del nastro 100 rispetto alle teste multi-fascio 13. An edging apparatus 10 according to the present invention also allows to easily adapt the speed? relative of the tape 100 with respect to the multi-bundle heads 13.
Infatti, se tale velocit? ? bassa sar? possibile ridurre il numero di teste multi-fascio 13 attive e viceversa se la velocit? ? elevata sar? possibile aumentare il numero di teste multi-fascio 13 attive, oppure degli emettitori delle stesse, per mantenere ad un valore prestabilito la densit? di potenza trasmessa al nastro 100. In fact, if this speed? ? low will be? possible to reduce the number of active multi-beam heads 13 and vice versa if the speed? ? high will be? Is it possible to increase the number of active multi-beam heads 13, or of the emitters thereof, to maintain the density at a predetermined value? of power transmitted to the belt 100.
Una forma di attuazione che consente una particolare flessibilit? nell?attivazione delle teste multi-fascio 13 prevede che l?apparato di bordatura 10 vantaggiosamente comprende mezzi motori, non illustrati, per muovere almeno una delle teste multifascio 13 rispetto alla posizione occupata, in uso, dal nastro 100. A form of implementation that allows a particular flexibility? in activating the multi-bundle heads 13 it provides that the edging apparatus 10 advantageously comprises motor means, not shown, for moving at least one of the multi-bundle heads 13 with respect to the position occupied, in use, by the belt 100.
In particolare, tale flessibilit? ? migliorata se l?apparato di bordatura 10 vantaggiosamente comprende mezzi di ri-posizionamento configurati per muovere almeno una delle teste multi-fascio 13. In particular, this flexibility? ? improved if the edging apparatus 10 advantageously comprises repositioning means configured to move at least one of the multi-bundle heads 13.
Questi mezzi di ri-posizionamento sono azionabili per, in uso, orientare la o le teste multi-fascio 13 per regolare, in uso, la posizione relativa delle zone A sul nastro 100 in modo da modulare la potenza specifica trasmessa al nastro 100 e/o per modulare l?estensione di una parte di superficie del nastro 100 interessata dalle zone A. These re-positioning means are operable to, in use, orient the multi-beam head or heads 13 to adjust, in use, the relative position of the zones A on the belt 100 so as to modulate the specific power transmitted to the belt 100 and / o to modulate the extension of a part of the surface of the belt 100 affected by the zones A.
Almeno una delle teste multi-fascio 13 ha una direzione di emissione dei fasci laser emessi in uso da detti emettitori 12 che, in un piano perpendicolare alla direzione longitudinale C? di detto nastro 100, incide su quest?ultimo formando un angolo retto rispetto alla faccia termo-attivabile 100a. At least one of the multi-beam heads 13 has an emission direction of the laser beams emitted in use by said emitters 12 which, in a plane perpendicular to the longitudinal direction C? of said tape 100, impacts on the latter forming a right angle with respect to the thermo-activatable face 100a.
Particolare flessibilit? di impiego si ha in una forma realizzativa della presente invenzione nella quale i mezzi di ri-posizionamento sono configurati in modo tale da essere atti a ruotare F e/o traslare G le teste multi-fascio 13 rispetto alla posizione che in uso ? occupata dal nastro 100. Particular flexibility of use occurs in an embodiment of the present invention in which the re-positioning means are configured in such a way as to be able to rotate F and / or translate G the multi-beam heads 13 with respect to the position in use? occupied by tape 100.
In tal modo sono possibili le configurazioni esemplificate nelle figure 4a e 4b. In this way the configurations exemplified in Figures 4a and 4b are possible.
Nella prima di queste ? rappresentata una configurazione adatta al caso in cui sia richiesta una minore potenza termica (ad esempio nel caso di un nastro di altezza minore) per cui solo la prima 13a e la terza 13c delle teste multi-fascio 13 sono attive nel qual caso 5 sono avanzate verso il nastro 100 mentre la seconda 13b ? inattiva e arretrata rispetto a quest?ultimo. In the first of these? shown a configuration suitable for the case in which a lower thermal power is required (for example in the case of a tape of lower height) for which only the first 13a and the third 13c of the multi-bundle heads 13 are active in which case 5 are advanced towards the belt 100 while the second 13b? inactive and behind the latter.
Se, partendo da tale configurazione, fosse richiesta una maggiore potenza di riscaldamento del nastro, ad esempio perch? si lavora un nastro di altezza maggiore, 10 allora mediante i mezzi motori verrebbero fatte arretrare la prima 13a e la terza 13c delle teste multi-fascio 13 e verrebbe fatta avanzare e attivata la terza 13b delle teste multi-fascio 13 cos? da ottenere la possibilit? di irradiare una zona pi? estesa con i 15 fasci emessi dagli emettitori 12. If, starting from this configuration, a greater heating power of the belt is required, for example why? a strip of greater height is worked, 10 then by means of the motor means the first 13a and the third 13c of the multi-bundle heads 13 would be moved back and the third 13b of the multi-bundle heads 13 would be moved forward and activated. to obtain the possibility? to irradiate an area pi? extended with the 15 beams emitted by the 12 emitters.

A particularly efficient effect occurs when each emitter 12 further comprises a collimator 16, adapted to collimate a laser light beam, connected to the exit section of the light guide 15.

In particolare, poich? in caso di guasto di un singolo diodo/emettitore, si ha solamente una contetuta riduzione della radiazione emessa e, quindi, il sistema pu? continuare a funzionare con velocit? relative tra teste e nastro, leggermente inferiori. In particular, since? in case of failure of a single diode / emitter, there is only a contetuta reduction of the emitted radiation and, therefore, the system can? continue to work with speed? relative between heads and belt, slightly lower.
