DESCRIZIONE dell ' invenzione industriale dal titolo : DESCRIPTION of the industrial invention entitled:
PROCEDIMENTO PER FORMARE CILINDRI , PARTICOLARMENTE PER LA GOFFRATURA DI NASTRI DI CARTA PROCEDURE FOR FORMING CYLINDERS, ESPECIALLY FOR EMBOSSING PAPER TAPES
TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
La presente invenzione si riferisce ad un procedimento per formare cilindri, particolarmente per la goffratura di nastri di carta tipo "tissue", come, ad esempio, carta da cucina, carta igienica, ecc. The present invention relates to a process for forming cylinders, particularly for embossing "tissue" type paper tapes, such as, for example, kitchen paper, toilet paper, etc.
Le macchine per la goffratura della carta, per esempio per la realizzazione di rotoli di carta da cucina compositi a due veli, comprendono due cilindri di goffratura, ciascuno presentante una serie di protuberanze disposte in file parallele e ciascuno cooperante con un rispettivo cilindro di pressione per goffrare ciascun foglio. Paper embossing machines, for example for the production of two-ply composite kitchen paper rolls, comprise two embossing cylinders, each having a series of protrusions arranged in parallel rows and each cooperating with a respective pressure cylinder for emboss each sheet.
I cilindri di goffratura sono avvicinati in modo tale da unire i due fogli goffrati facendo preferibilmente coincidere le punte. Uno dei due cilindri di goffratura viene inoltre cosparso di colla per incollare i due fogli. The embossing cylinders are brought together in such a way as to join the two embossed sheets by preferably making the tips coincide. One of the two embossing cylinders is also sprinkled with glue to glue the two sheets.
Le protuberanze dei cilindri di goffratura vengono realizzate per asportazione di truciolo, oppure mediante procedimenti chimici di asportazione di materiale, in modo tale che i fogli presentino un puntinatura regolare costituita da righe parallele di punte rivolte verso l'interno, vale a dire sui lati affacciati dei fogli stessi. The protuberances of the embossing cylinders are made by chip removal, or by chemical material removal procedures, in such a way that the sheets have a regular dot consisting of parallel rows of points facing inwards, i.e. on the facing sides of the sheets themselves.
Una condizione vantaggiosa affinché i due fogli rimangano stabilmente associati è tuttavia che il maggior numero possibile di rilievi di un foglio combacino con quelli dell'altro foglio per garantire un'ampia superficie di incollaggio. Oppure nel cosiddetto sistema "sfasato", i rilievi di un foglio devono coincidere con gli spazi compresi tra i rilievi dell'altro foglio . An advantageous condition for the two sheets to remain stably associated, however, is that the greatest possible number of reliefs of one sheet match those of the other sheet to ensure a large gluing surface. Or in the so-called "out of phase" system, the reliefs of one sheet must coincide with the spaces between the reliefs of the other sheet.
Compito precipuo della presente invenzione è quello di realizzare un procedimento per formare cilindri, particolarmente per la goffratura di nastri di carta, atti a realizzare motivi ornamentali anche complessi sul prodotto finito. The aim of the present invention is to provide a process for forming cylinders, particularly for embossing paper webs, suitable for creating even complex ornamental motifs on the finished product.
Nell'ambito di questo compito, uno scopo del trovato, è quello di realizzare un procedimento estremamente più economico, dal punto di vista produttivo, rispetto ai sistemi noti. Within the scope of this aim, an object of the invention is to provide an extremely cheaper method, from the production point of view, with respect to known systems.
Un altro scopo è quello di realizzare un procedimento in grado di produrre motivi ornamentali o disegni, più o meno complessi secondo le esigenze, ma sempre con estrema precisione e riproducibilità, anche speculare, su diversi cilindri. Another object is to provide a process capable of producing ornamental motifs or designs, more or less complex according to requirements, but always with extreme precision and reproducibility, even specular, on different cylinders.
Questo compito, nonché questi ed altri scopi che meglio appariranno in seguito, sono raggiunti da un procedimento per formare cilindri, particolarmente per la goffratura di nastri di carta comprendente una prima operazione di formatura di una serie di protuberanze ed una seconda operazione di formatura di un motivo o disegno comprendente l'asportazione, almeno parziale, di un certo numero di dette protuberanze. This task, as well as these and other purposes which will become clearer hereinafter, are achieved by a process for forming cylinders, particularly for embossing paper webs comprising a first operation of forming a series of protuberances and a second operation of forming a motif or design comprising the removal, at least partially, of a certain number of said protuberances.
Ulteriori caratteristiche e vantaggi risulteranno maggiormente dalla descrizione di una forma di realizzazione preferita, ma non esclusiva, dell'invenzione, illustrata a titolo indicativo e non limitativo negli uniti disegni in cui: Further characteristics and advantages will become clearer from the description of a preferred, but not exclusive, embodiment of the invention, illustrated by way of non-limiting example in the accompanying drawings in which:
la figura 1 è una vista prospettica schematica di un cilindro di goffratura realizzato secondo l'invenzione; e Figure 1 is a schematic perspective view of an embossing cylinder made according to the invention; And
la figura 2 è una vista parziale ingrandita di una porzione della superficie del cilindro secondo l'invenzione. Figure 2 is an enlarged partial view of a portion of the surface of the cylinder according to the invention.
Il cilindro di goffratura, secondo l'invenzione, indicato genericamente con il numero di riferimento 1, è atto ad essere utilizzato in una macchina per realizzare carta goffrata sostanzialmente convenzionale, del tipo comprendente due cilindri di goffratura montati con gli assi paralleli in modo tale che la superficie di goffratura dei due cilindri sia a contatto in corrispondenza delle punte delle protuberanze affacciate di ciascun cilindro. The embossing cylinder, according to the invention, generically indicated with the reference number 1, is adapted to be used in a machine for making substantially conventional embossed paper, of the type comprising two embossing cylinders mounted with parallel axes in such a way that the embossing surface of the two cylinders is in contact at the tips of the facing protuberances of each cylinder.
In modo di per sé noto, ciascun cilindro di goffratura coopera con un rispettivo cilindro di pressione in gomma o altro materiale cedevole per realizzare la goffratura sul rispettivo nastro di carta. Due nastri di carta sono infatti alimentati rispettivamente nella prima coppia e nella seconda coppia cilindro di goffratura-cilindro di pressione, per essere goffrati. I due nastri, una volta goffrati, vengono uniti in corrispondenza della linea di contatto tra i due cilindri di goffratura per ottenere un nastro di carta a due veli. In a per se known manner, each embossing cylinder cooperates with a respective pressure cylinder made of rubber or other compliant material to emboss the respective paper web. Two paper webs are in fact fed respectively into the first pair and into the second embossing cylinder-pressure cylinder pair, to be embossed. The two webs, once embossed, are joined at the contact line between the two embossing cylinders to obtain a two-ply paper web.
Secondo l'invenzione, il cilindro di goffratura viene realizzato con una prima operazione di formatura di una serie regolare di protuberanze 3, per esempio mediante asportazione di truciolo. Possono essere eseguite eventuali operazioni di finitura oppure si passa direttamente ad una seconda operazione di formatura di un disegno ornamentale 5 comprendente l'asportazione, almeno parziale, di un certo numero di protuberanze . According to the invention, the embossing cylinder is made with a first operation of forming a regular series of protuberances 3, for example by removing chips. Possible finishing operations can be carried out or a second operation of forming an ornamental design 5 can be carried out, comprising the removal, at least partially, of a certain number of protuberances.
L'asportazione delle protuberanze può essere vantaggiosamente eseguita con una macchina a controllo numerico, ad esempio una fresatrice. Ciò permette di riprodurre ciascun motivo ornamentale o disegno in modo perfetto ed anche speculare sul secondo cilindro. E' infatti molto importante che il maggior numero possibile di punte affacciate delle protuberanze dei due cilindri combacino per assicurare un buon incollaggio dei due veli. The removal of the protuberances can be advantageously carried out with a numerically controlled machine, for example a milling machine. This allows to reproduce each ornamental motif or design in a perfect way and also to mirror the second cylinder. It is in fact very important that the greatest possible number of facing points of the protuberances of the two cylinders match to ensure a good bonding of the two plies.
Realizzando infatti il disegno in modo specularmente identico sui due cilindri di goffratura, tutte le punte di un cilindro coincideranno con tutte le punte dell'altro cilindro garantendo il massimo numero di punti di incollaggio tra i due veli. In fact, by making the design specularly identical on the two embossing cylinders, all the points of one cylinder will coincide with all the points of the other cylinder, guaranteeing the maximum number of gluing points between the two plies.
Si è in pratica constatato come 1'invenzione raggiunga il compito e gli scopi prefissati avendo realizzato un procedimento per formare cilindri di goffratura con motivi ornamentali anche molto complessi. In practice it has been found that the invention achieves the intended aim and objects, having carried out a process for forming embossing cylinders with even very complex ornamental motifs.
Il procedimento secondo l'invenzione, è suscettibile di numerose modifiche e varianti, tutte rientranti nell'ambito del concetto inventivo; inoltre tutti i dettagli potranno essere sostituiti da elementi tecnicamente equivalenti. The process according to the invention is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept; furthermore, all the details can be replaced by technically equivalent elements.
Ad esempio, le operazioni descritte possono essere realizzate anche in ordine inverso. For example, the described operations can also be carried out in reverse order.
Naturalmente i materiali impiegati, nonché le dimensioni, potranno essere qualsiasi secondo le esigenze e lo stato della tecnica. The materials used, as well as the dimensions, may of course be any according to the requirements and the state of the art.
