Independent claims are included for: (a) a method for making the packing material; and (b) a machine for making it.

Description

La présente invention concerne un matériau de calage et remplissage d'emballage ainsi que le procédé et la machine pour sa fabrication.The present invention relates to a filling and filling material packaging as well as the process and the machine for its manufacture.

Plus précisément, la présente invention concerne un matériau de protection des objets renfermés dans un emballage, le dit matériau ayant une action de calage et/ou de remplissage des espaces libres et/ou d'amortissement des chocs et de résistance à la pression.More specifically, the present invention relates to a material for protecting objects enclosed in a package, the said material having a wedging action and / or filling of free spaces and / or shock absorption and resistance to pressure.

ÉTAT DE LA TECHNIQUESTATE OF THE ART

Divers matériaux et systèmes ont déjà été proposés comme matériau de calage et remplissage d'emballage.Various materials and systems have already been proposed as cushioning material and packing filling.

Le principal matériau utilisé consiste en des mousses polymériques ou des matériaux synthétiques expansés. Ces matériaux sont utiles en ce qu'ils remplissent les cavités irrégulières formées entre l'objet emballé et le récipient d'emballage. Mais les grands inconvénients de ces matériaux sont de nécessiter d'être produits par des entreprises spécialisées, et d'exiger de grands volumes de transports et de stockage.The main material used consists of polymeric foams or expanded synthetic materials. These materials are useful in that they fill the irregular cavities formed between the packaged object and the packaging container. But the main disadvantages of these materials are that they have to be produced by specialized companies, and to demand large volumes of transport and storage.

De nombreux autres matériaux et systèmes de calage et remplissage ont été proposés.Many other packing and filling materials and systems have been proposed.

Le brevet US 3244347 décrit un système de calage et remplissage d'emballage, mais limité aux coins des emballages. Le système n'est pas adapté au remplissage des cavités irrégulières entre l'objet emballé et le récipient d'emballage.US Patent 3,244,347 describes a packaging wedging and filling system, but limited to the corners of the packaging. The system is not suitable for filling irregular cavities between the wrapped object and the packaging container.

Il en est de même pour la demande de certificat français 2624103.The same is true for the French certificate request 2624103.

Divers documents ont décrit des systèmes d'amortissement des chocs formant des matelas ou des éléments d'emballage, mais ces systèmes ne sont pas adaptés au remplissage de cavités irrégulières entre l'objet emballé et le récipient d'emballage.Various documents have described shock absorption systems forming mattresses or packing materials, but these systems are not suitable for filling of irregular cavities between the wrapped object and the packaging container.

Parmi les documents de ce type, on peut citer la demande de brevet européen 602580 qui met en oeuvre un matelas à structure en treillis ; la demande de brevet européen 888879 qui met en oeuvre un matelas à forme plissée ou ondulée ; la demande de brevet international WO 93/16940 qui met en oeuvre des éléments d'emballage préformé à poches coniques, l'angle d'ouverture du cône étant compris entre des limites bien précises.Among the documents of this type, we can cite the European patent application 602580 which implements a lattice structure mattress; the patent application European 888879 which uses a pleated or wavy mattress; the international patent application WO 93/16940 which implements elements of preformed packaging with conical pockets, the cone opening angle included between very precise limits.

Le brevet US 5173352 a proposé des bandelettes plissées en accordéon, mais les propriétés de ces matériaux sous l'aspect du calage et de la résistance à l'écrasement sont médiocres du fait que les bandelettes s'imbriquent plus ou moins les unes dans les autres.US Patent 5,173,352 has proposed accordion pleated strips, but the properties of these materials in terms of cushioning and resistance to the crushing is poor due to the fact that the strips overlap more or less into each other.

La demande de brevet allemand 4018173 a proposé des matériaux protecteurs de calage (ou rembourrage) et de remplissage constitué de corps creux en forme de cylindres ou prismes dérivés de bandelettes prédécoupées dont les deux bouts sont collés ensemble ou coincés l'un dans l'autre. Mais ces matériaux ont une résistance à l'écrasement médiocre et s'aplatissent trop facilement. L'usage d'éléments en feuille de papier est reconnu comme permettant d'éviter le polystyrène expansé.German patent application 4018173 proposed protective materials cushioning (or padding) and filling consisting of hollow bodies in the form of cylinders or prisms derived from precut strips, the two ends of which are glued together or stuck together. But these materials have resistance to poor crushing and flatten too easily. The use of sheet elements of paper is recognized as making it possible to avoid expanded polystyrene.

Plusieurs autres documents ont alors proposé des matériaux du type matériau de calage ou de remplissage en forme de cuvette ou de godets obtenus à partir de feuilles de papier.Several other documents then proposed materials of the material type dunnage or filling in the form of a bowl or cups obtained from sheets of paper.

Le brevet US 5595811 de priorité 31 janvier 1992 a proposé de tels éléments de papier en forme de cuvette avec un plissage du papier plus ou moins accentué, les divers plis partants tous du fond de la cuvette.Patent US 5595811 of priority January 31, 1992 proposed such elements of bowl-shaped paper with more or less accentuated pleating of the paper, the various folds starting all from the bottom of the bowl.

La demande de brevet international WO 94/07765, de priorité 5 octobre 1992, décrit des éléments d'amortissement des chocs, en forme de dé à coudre, ayant un fond plat de diamètre compris entre 1,27 et 2,54 cm, et une paroi de type tubulaire. Ces éléments de remplissage en forme de dé à coudre sont obtenus par emboutissage d'une feuille de papier par un mandrin traversant une matrice ; la feuille de papier conformée se dégage du mandrin grâce à l'expansion naturelle des plis de la paroi après que le mandrin ait traversé la matrice.International patent application WO 94/07765, with priority of October 5, 1992, describes shock absorbing elements, in the shape of a thimble, having a flat bottom with diameter between 1.27 and 2.54 cm, and a tubular type wall. These thimble-shaped filling elements are obtained by stamping a sheet of paper through a mandrel passing through a die; the piece of paper shape emerges from the mandrel thanks to the natural expansion of the folds of the wall after the mandrel has passed through the die.

La demande de brevet européen 667304 décrit un matériau de rembourrage constitué de corps creux dérivés de bandelettes semblables à ceux de la demande allemande 4018173 ; mais ces corps creux peuvent aussi, soit être pourvus de plis longitudinaux, soit avoir un fond raide leur donnant une forme générale de pot. Dans ce cas les plis s'étendent parallèlement les uns aux autres à partir (ou en direction) du fond du pot.European patent application 667304 describes a padding material consisting of hollow bodies derived from strips similar to those of the application German 4018173; but these hollow bodies can also either be provided with folds longitudinal, or have a steep bottom giving them a general pot shape. In in this case the folds extend parallel to each other from (or towards) the bottom of the pot.

Les matériaux de calage ou rembourrage ou remplissage ayant ces formes de cuvette selon ces trois derniers documents ont généralement une résistance médiocre à l'écrasement, notamment sous l'effet de forces de direction transversale aux parois latérales, et ils s'aplatissent facilement.Lining or padding or filling materials having these forms of bowl according to these last three documents usually have resistance poor crushing, especially due to transverse steering forces side walls, and they flatten out easily.

L'existence d'un fond raide selon la demande 667304 améliore la résistance à l'écrasement, mais insuffisamment. La conformation de type « petits dés à coudre » selon la demande internationale WO 94/07765 améliore aussi la résistance à l'écrasement mais la nécessité de fabriquer un grand nombre de ces « dés », vu leur petitesse, complique le procédé de fabrication.The existence of a stiff bottom according to application 667304 improves the resistance to crushing, but insufficiently. The "small thimbles" type conformation according to international application WO 94/07765 also improves resistance to the crash but the need to make many of these "dice", given their smallness, complicates the manufacturing process.

L'INVENTIONTHE INVENTION

Sous un premier aspect, l'invention concerne un élément de calage et/ou remplissage d'emballage caractérisé en ce que

  • a) le dit élément est constitué de papier, et
  • b) l'élément a une forme générale de godet (ou cuvette), ayant un évidement central (b1) et un fond (b2) et une paroi latérale tout autour, et
  • c) cette paroi est épaisse et non unie, son épaisseur moyenne étant de préférence plus de 10 fois supérieure à celle du papier lui-même.
    • In a first aspect, the invention relates to a packing wedging and / or filling element characterized in that
  • a) the said element is made of paper, and
  • b) the element has a general shape of a cup (or bowl), having a central recess (b1) and a bottom (b2) and a side wall all around, and
  • c) this wall is thick and not united, its average thickness preferably being more than 10 times greater than that of the paper itself.

    • Dans la présente description on utilise le mot godet, ou cuvette, pour indiquer qu'il y a un fond comme dans un récipient quoique les parois plissées ne ressemblent pas à celles d'un godet habituel à parois unies.In the present description, the word bucket, or bowl, is used to indicate that there is a bottom like in a container although the folded walls do not resemble not those of a usual plain-walled bucket.

    Selon l'invention le fond du godet n'est pas plissé, mais ses parois sont non unies, et plus précisément plissées selon une configuration en zigzag irrégulier ; ce cette configuration en zigzag irrégulier est telle qu'obtenable (ou telle qu'obtenue) par l'écrasement d'une feuille de papier selon sa longueur, autrement dit transversalement à l'épaisseur de cette feuille, en direction du fond du godet.According to the invention the bottom of the bucket is not pleated, but its walls are not plain, and more precisely pleated in an irregular zigzag configuration; this this irregular zigzag configuration is as obtainable (or as obtained) by crushing a sheet of paper along its length, in other words transversely to the thickness of this sheet, towards the bottom of the bucket.

    Selon un autre aspect de l'invention les plis de la paroi du godet sont une pluralité de plis, généralement plus de 10, de préférence plus de 25 plis.According to another aspect of the invention, the folds of the wall of the bucket are a plurality of plies, generally more than 10, preferably more than 25 plies.

    Selon un autre aspect de l'invention, la majorité des plis (mais non pas tous) ne s'étendent pas à partir du (ou jusqu'au) fond (b2) du godet, et, avantageusement, ils s'entrecroisent les uns les autres, ou forment des angles ou intersections entre eux.According to another aspect of the invention, the majority of folds (but not all) do not not extend from (or to) the bottom (b2) of the bucket, and, advantageously, they intersect each other, or form angles or intersections between them.

    Selon un autre aspect de l'invention, une partie importante des plis (plus de 20% d'entre eux), généralement plus de 40% d'entre eux (mais moins de 95%), a une orientation générale approximative parallèle au plan représentant le fond (b2) du godet. Cette orientation parallèle au fond du godet exprime, selon ce qui sera vu plus loin à propos du procédé de fabrication des godets, que les parois épaisses sont issues d'un écrasement des feuilles de papier selon une direction sensiblement perpendiculaire au fond du godet. Ces plis approximativement parallèles, peuvent former des angles allant jusqu'à 45°, d'un côté ou de l'autre, avec le fond du godet.According to another aspect of the invention, a large part of the folds (more than 20% of them), generally more than 40% of them (but less than 95%), have a approximate general orientation parallel to the plane representing the bottom (b2) of the bucket. This orientation parallel to the bottom of the bucket expresses, as will be seen more far about the method of making the buckets, that the thick walls came from crushing of the sheets of paper in a direction substantially perpendicular to the bottom of the bucket. These approximately parallel folds can form angles up to 45 °, on one side or the other, with the bottom of the bucket.

    Les godets selon l'invention ont avantageusement une surface unie, de préférence le fond, plate ou arrondie permettant d'y inscrire de la publicité lisible commodément. Leur diamètre extérieur (moyen) global est compris entre 1 et 15 cm, de préférence entre 2.6 et 10 cm. Par contraste, les parois des godets, issues d'un écrasement, ne sont pas unies et ne permettent guère une publicité lisible commodément.The buckets according to the invention advantageously have a smooth surface, of preferably the bottom, flat or rounded allowing to inscribe readable advertising conveniently. Their overall (average) outside diameter is between 1 and 15 cm, preferably between 2.6 and 10 cm. In contrast, the walls of the buckets, from a overwrite, are not united and hardly allow a readable advertisement conveniently.

    Selon un aspect préféré de l'invention, le rapport (ou ratio) du volume de la pièce calante sur la surface du papier mis en oeuvre est compris dans une gamme allant de 0.01 à 5 cm3/cm2, de préférence de 0.05 à 1 cm3/cm2, et plus préférentiellement de 0,1 à 1 cm3/cm2 According to a preferred aspect of the invention, the ratio (or ratio) of the volume of the wedging piece on the surface of the paper used is in a range from 0.01 to 5 cm 3 / cm 2 , preferably from 0.05 to 1 cm 3 / cm 2 , and more preferably from 0.1 to 1 cm 3 / cm 2

    Le rapport (ou ratio) du volume du matériau de calage selon l'invention par rapport au volume initial de papier nécessaire à sa réalisation, est généralement compris entre 10 et 300, de préférence entre 40 et 200, et plus préférentiellement encore entre 50 et 100.The ratio (or ratio) of the volume of the cushioning material according to the invention by compared to the initial volume of paper necessary for its production, is generally between 10 and 300, preferably between 40 and 200, and more preferably still between 50 and 100.

    Selon un autre aspect avantageux de l'invention, les pièces calantes en forme générale de cylindre creux à parois latérales épaisses ont un rapport (ou ratio) du diamètre extérieur moyen du cylindre sur la hauteur du cylindre avantageusement compris entre 0.2 et 8, de préférence entre 0,9 et 6, plus préférentiellement entre 0,9 et 3. Le rapport (ou ratio) du diamètre extérieur du cylindre sur l'épaisseur moyenne de la paroi latérale est avantageusement compris entre 2.1 et 8, de préférence entre 2.2 et 6.According to another advantageous aspect of the invention, the shaped wedging pieces general hollow cylinder with thick side walls have a ratio (or ratio) of average outside diameter of the cylinder over the height of the cylinder advantageously between 0.2 and 8, preferably between 0.9 and 6, more preferably between 0.9 and 3. The ratio (or ratio) of the outside diameter of the cylinder to the average thickness of the side wall is advantageously between 2.1 and 8, preferably between 2.2 and 6.

    L'élément de calage et/ou rembourrage et/ou remplissage d'emballage est aussi appelé « pièce calante » dans le présent texte.The wedging and / or padding and / or packing filling element is also called “chocking piece” in the present text.

    L'invention porte également sur un matériau de calage et /ou remplissage d'emballage caractérisé en ce qu'il contient une pluralité d'éléments de calage selon l'invention, généralement plus de 10, avantageusement plus de 20. Cette pluralité peut comprendre jusqu'à une dizaine ou plusieurs dizaines de pièces calantes, voire des centaines, mais cela n'est pas une caractéristique essentielle de l'invention.The invention also relates to a cushioning and / or filling material. packaging characterized in that it contains a plurality of wedging elements according to the invention, generally more than 10, advantageously more than 20. This plurality can include up to ten or several dozen supporting parts, or even hundreds, but this is not an essential feature of the invention.

    La forme générale de cylindre creux, à parois épaisses, des pièces calantes telles que définies dans l'invention donne à celles-ci et au(x) matériau(x) de calage les comprenant une excellente résistance à l'écrasement ou au chocs extérieurs.The general shape of a hollow cylinder, with thick walls, wedging pieces as defined in the invention gives these and the (x) wedging material (s) including excellent resistance to crushing or external impact.

    Un avantage de l'invention est que les pièces calantes sont bien résistantes mécaniquement, notamment résistantes à l'écrasement ou aux forces déformantes diverses, les déformations étant d'autant plus à éviter qu'elles pourraient faire perdre le caractère calant des dites pièces.An advantage of the invention is that the wedging pieces are very resistant mechanically, in particular resistant to crushing or to deforming forces various, the deformations being all the more to be avoided as they could cause loss the stalling nature of said pieces.

    Un autre avantage de l'invention est que le matériau de calage a un effet calant excellent, et un très bon taux d'occupation des volumes vides dans les emballages.Another advantage of the invention is that the cushioning material has a cushioning effect excellent, and a very good occupancy rate of empty volumes in packaging.

    Un autre avantage des éléments de calage et de remplissage selon l'invention est qu'ils n'ont pas tendance à ou la possibilité de s'imbriquer les uns dans les autres.Another advantage of the wedging and filling elements according to the invention is that they don't tend to or have the ability to nest into each other.

    L'utilisation de papier rigide, voire très rigide, est recommandée dans l'invention parce qu'il favorise l'obtention de pièces calantes résistant mieux à l'écrasement. Le papier connu sous le nom de papier Kraft est particulièrement avantageux pour obtenir ce résultat. On peux aussi utiliser des papiers recyclables et/ou recyclés, mais on préfère les papiers non recyclés et tous ceux n'ayant pas tendance naturellement à se déplier.The use of rigid or even very rigid paper is recommended in the invention because it promotes obtaining wedging parts which are more resistant to crushing. The paper known as Kraft paper is particularly advantageous to obtain this result. We can also use recyclable papers and / or recycled, but we prefer non-recycled paper and all those that do not have naturally tends to unfold.

    Le papier mis en oeuvre dans l'invention peut être multicouche, mais on préfère généralement, notamment pour des raisons d'efficacité et d'économie, utiliser du papier mono-couche.The paper used in the invention can be multilayer, but it is preferred generally, especially for reasons of efficiency and economy, use single layer paper.

    PROCÉDÉ DE FABRICATION DU MATÉRIAU DE CALAGEMETHOD FOR MANUFACTURING THE SET MATERIAL

    Par ailleurs, l'invention concerne également un procédé de fabrication de matériau de calage ainsi qu'une machine destinée à mettre en oeuvre ce procédé.Furthermore, the invention also relates to a method for manufacturing cushioning material as well as a machine intended to implement this process.

    Le procédé selon l'invention est un procédé pour réaliser un matériau de calage, ou une pluralité de pièces calantes, ce procédé comprenant les étapes suivantes :

  • 1) découper une bande de papier en une pluralité de petites feuilles de papier,
  • 2) emboutir les feuilles de papier au travers d'un trou d'une matrice, cet emboutissage conduisant à la formation de cuvettes préliminaires en papier dont les bords ont une forme générale tubulaire,
  • 3) écraser les parois de papier des cuvettes selon une direction sensiblement parallèle à l'axe du tube de ces cuvettes préliminaires et en direction du fond de ces cuvettes. Des aspects préférés du procédé selon l'invention sont les suivants, pris séparément ou en combinaison :
  • 4) l'emboutissage de la feuille de papier au travers d'un trou (ou canal creux) est tel que le trou a un diamètre approximativement égal au diamètre des éléments de calage qu'on cherche à fabriquer,
  • 5) l'emboutissage se fait sur une pièce de papier découpée dans un rouleau de papier qu'on déroule,
  • 6) la ou les bandes de papier qu'on découpe sont issues d'une rouleau de papier qu'on déroule,
  • 7) les diverses étapes du procédé de l'invention (opérations de déroulement, découpage, emboutissage, écrasement) sont exécutées successivement et répétitivement, et en continu,
  • 8) les moyens d'emboutissage sont un mandrin cylindrique ayant un axe de translation identique à celui du trou de la matrice.
  • 9) les moyens d'écrasement sont un manchon cylindrique coulissant autour du mandrin,
  • 10) l'emboutissage et l'écrasement se font en mettant en oeuvre des moyens empêchant le coinçage du papier d'une part entre les moyens d'écrasement et les parois du trou (ou canal creux) de la matrice, et d'autre part entre les moyens d'emboutissage et les moyens d'écrasement
  • 11) les moyens empêchant le coinçage du papier sont constitués par un rainurage ou une cannelure ou dentelure disposé longitudinalement sur les parties (cylindres en général) dont on veut éviter le coincement (soit le mandrin et le manchon, soit le manchon et le trou de la matrice). Ces rainurages ou dentelure ou cannelure ont des formes correspondantes pour permettre un coulissage l'un dans l'autre. Selon une modalité plus particulière du procédé selon l'invention, celui-ci consiste à :
  • 21) alimenter la machine à l'aide de papier sous forme de feuille plane (mono- ou multi-couche, de préférence mono-couche), cette alimentation amenant le papier plan en position obturant l'ouverture de canaux creux,
  • 22) découper le dit papier selon des bandes parallèles, de préférence longitudinalement,
  • 23) découper, de préférence transversalement, les bandes parallèles de manière à former des petites feuilles de surface restreinte (de préférence des rectangles ou carrés) de papier, les étapes 22) et 23) pouvant être simultanées ou différées par rapport à l'étape 21) ou pouvant la précéder,
  • 24) enfoncer les petites feuilles de papier à l'intérieur des canaux creux d'une matrice à l'aide de moyens de poussage (ou emboutissage ; ces moyens, de préférence un mandrin, poussant les petites feuilles de préférence en leur centre), jusqu'à ce que les petites feuilles aient pénétré, de préférence entièrement, dans le(s) dit(s) canaux creux, et que les centres des dites petites feuilles butent contre des surfaces rigides ou butoirs,
  • 25) pousser les parties latérales des dites petites feuilles en direction des butoirs ou surfaces rigides de manière à produire un écrasement, cet écrasement générant une forme multiplissée irrégulière pour les dites parties latérales écrasées,
  • 26) retirer le butoir ou surface rigide pour libérer, hors des canaux creux, les pièces de papier ainsi formées,
  • 27) faire sortir les dites pièces de papier ainsi formées (ou pièces calantes), hors des canaux creux de la matrice,
  • 28) collecter les pièces de papier ainsi formées de manière à constituer un matériau de calage, lui-même constitué d'une pluralité de pièces calantes.
    • The method according to the invention is a method for producing a wedging material, or a plurality of wedging pieces, this method comprising the following steps:
  • 1) cut a strip of paper into a plurality of small sheets of paper,
  • 2) stamping the sheets of paper through a hole in a die, this stamping leading to the formation of preliminary paper bowls whose edges have a generally tubular shape,
  • 3) crush the paper walls of the bowls in a direction substantially parallel to the axis of the tube of these preliminary bowls and towards the bottom of these bowls. Preferred aspects of the process according to the invention are the following, taken separately or in combination:
  • 4) the drawing of the sheet of paper through a hole (or hollow channel) is such that the hole has a diameter approximately equal to the diameter of the wedging elements which it is sought to manufacture,
  • 5) the stamping is done on a piece of paper cut from a roll of paper which is unrolled,
  • 6) the strip or strips of paper that are cut come from a roll of paper that is unrolled,
  • 7) the various stages of the process of the invention (unwinding operations, cutting, stamping, crushing) are carried out successively and repetitively, and continuously,
  • 8) the drawing means are a cylindrical mandrel having an axis of translation identical to that of the hole in the die.
  • 9) the crushing means are a cylindrical sleeve sliding around the mandrel,
  • 10) the stamping and the crushing are done by implementing means preventing the wedging of the paper on the one hand between the crushing means and the walls of the hole (or hollow channel) of the matrix, and on the other hand part between the drawing means and the crushing means
  • 11) the means preventing the jamming of the paper are constituted by a grooving or a groove or serration arranged longitudinally on the parts (cylinders in general) which one wants to avoid jamming (either the mandrel and the sleeve, or the sleeve and the hole of the matrix). These grooves or serration or groove have corresponding shapes to allow sliding in one another. According to a more specific method of the method according to the invention, it consists in:
  • 21) feeding the machine with paper in the form of a flat sheet (mono- or multi-layer, preferably single-layer), this feeding bringing the flat paper into position closing the opening of hollow channels,
  • 22) cut the said paper in parallel strips, preferably longitudinally,
  • 23) cut, preferably transversely, the parallel strips so as to form small sheets of restricted surface (preferably rectangles or squares) of paper, steps 22) and 23) being able to be simultaneous or different from the step 21) or may precede it,
  • 24) press the small sheets of paper inside the hollow channels of a matrix using pushing means (or stamping; these means, preferably a mandrel, pushing the small sheets preferably in their center), until the small leaves have penetrated, preferably entirely, into said hollow channel (s), and the centers of said small leaves abut against rigid surfaces or buffers,
  • 25) pushing the lateral parts of the said small sheets in the direction of the bumpers or rigid surfaces so as to produce a crushing, this crushing generating an irregular multiplied shape for the said crushed lateral parts,
  • 26) remove the stopper or rigid surface to release, out of the hollow channels, the pieces of paper thus formed,
  • 27) bringing out the said pieces of paper thus formed (or wedging pieces), out of the hollow channels of the matrix,
  • 28) collecting the pieces of paper thus formed so as to constitute a wedging material, itself made up of a plurality of wedging pieces.

    • L'alimentation de la première étape à l'aide de papier sous forme de (grande) feuille plane est avantageusement réalisée par déroulement d'un rouleau de papier. Cette variante de l'invention est particulièrement avantageuse en ce que le stockage de tels rouleaux de papiers tient peu de volume, et est peu inflammable (= peu enflammable), en tout cas beaucoup moins inflammable que le matériau de calage en polystyrène expansé. Feeding the first stage using paper in the form of (large) flat sheet is advantageously produced by unwinding a roll of paper. This variant of the invention is particularly advantageous in that the storage such rolls of paper hold little volume, and are not very flammable (= little ignitable), in any case much less flammable than the cushioning material expanded polystyrene.

    Les canaux creux sont de préférence de forme cylindrique, pouvant être notamment en forme d'un cylindre à base ronde ou polygonale, régulière ou irrégulière ; cette forme peut être dentelée ou cannelée ou rainurée.The hollow channels are preferably cylindrical in shape, which can be in particular in the form of a cylinder with a round or polygonal base, regular or irregular; this shape can be serrated or grooved or grooved.

    Les petites feuilles de papier ont, comme indiqués ci-avant, une surface restreinte. Par surface restreinte, on entend que la surface des petites feuilles est plus petite que celle de la grande feuille initiale, dans la mesure ou la grande feuille a subi un découpage, et même deux découpages, l'un longitudinal, l'autre transversal. Sur un plan pratique ces petites feuilles de surface restreinte ont souvent une forme de rectangle ou de carré ou de cercle, la dimension des côtés (ou le diamètre pour un cercle) étant souvent comprise entre 3 et 40 cm, de préférence entre 4 et 25 cm, plus préférentiellement entre 5 et 20 cm.The small sheets of paper have, as indicated above, a surface restraint. By restricted surface is meant that the surface of the small leaves is more small than that of the initial large leaf, insofar as the large leaf has undergone a cutting, and even two cutting, one longitudinal, the other transverse. Sure a practical plan these small sheets of restricted surface often have a form of rectangle or square or circle, the dimension of the sides (or the diameter for a often being between 3 and 40 cm, preferably between 4 and 25 cm, more preferably between 5 and 20 cm.

  • Comme déjà dit à propos du procédé, les canaux creux sont de préférence cylindriques. Ces cylindres creux (15), aussi bien que les autres cylindres mentionnés dans la description de l'invention, peuvent être des cylindres à base ronde ou polygonale, régulière ou irrégulière.
  • Les moyens de poussage ou écrasement (6) peuvent être sous forme de cylindres, ou de disques (c'est-à-dire un cylindre de faible épaisseur) liés à une ou des tiges (ou barres), celles-ci servant à relier les moyens actionnant le mouvement et les disques exerçant le poussage ou écrasement des feuilles de papier. Ces moyens de poussage peuvent aussi avoir un forme de piston.
  • Les moyens de poussage ou écrasement (6) sont capables de coulisser dans les canaux (ou cylindre) creux (15).
  • Les moyens de poussage ou emboutissage (5) sont avantageusement des cylindres, pouvant coulisser à l'intérieur des moyens de poussages (6). Pour des raisons de qualité et de sécurité, il est avantageux que ces cylindres aient un bout arrondi, voire sphérique ou ovoïdal.
  • Les moyens d'éviter les coincements de papier sont avantageusement des rainurages ou dentelures ou cannelures disposés sur les parois intérieures ou extérieures des cylindres, notamment des canaux (ou cylindres) creux (15), des moyens de poussage (6), et des moyens de poussage (5), notamment lorsque ces moyens de poussages (5) et (6) sont cylindriques. La taille et la forme des cannelures ou rainures peuvent varier largement sans sortir du cadre de l'invention. Généralement la taille de ces rainures ou dentelures ou cannelures sont comprises entre 1/2 mm et 1 cm, mais des tailles dépassant ces limites peuvent aussi être utilisées sans sortir du cadre de l'invention. Les rainures ou dentelures ou cannelures sont avantageusement disposées sur plus de la moitié de la surface des cylindres (canaux creux et moyens de poussage), de préférence sur plus des 2/3 de ces surfaces, et encore plus préférentiellement sur la totalité de ces surfaces.
  • Les moyens (56) permettant un poussage différé des moyens (6) de poussage et écrasement des parties latérales (16) et des moyens (5) de poussage et emboutissage des centres des petites feuilles, sont avantageusement constitués par des ressorts (ou un moyen équivalent) conservant un décalage spatial entre les moyens (6) et les moyens (5). En actionnant le poussage des moyens (6), les moyens (5) qui sont maintenus en position décalée et avancée, poussent les centres des petites feuilles. Quand ces moyens (5) butent contre les surfaces rigides (4), alors les moyens actionnant le poussage des moyens de poussage (6) prévalent sur les ressorts [ou moyens (56) maintenant le décalage entre (6) et (5)] et le poussage des parties latérales (16) des petites feuilles se met en oeuvre postérieurement au poussage des centres (1) des petites feuilles.
  • Dans ce qui précède, le poussage différé des moyens (6) et (5) a été présenté comme réalisé par le moyen de ressorts. D'autres systèmes peuvent être utilisés, notamment des moteurs actionnant séparément et successivement les moyens (5) puis les moyens (6).
    • More specifically, the above-described means can be implemented in the following manner:
  • As already said about the method, the hollow channels are preferably cylindrical. These hollow cylinders (15), as well as the other cylinders mentioned in the description of the invention, can be cylinders with a round or polygonal base, regular or irregular.
  • The pushing or crushing means (6) can be in the form of cylinders, or discs (that is to say a thin cylinder) linked to one or more rods (or bars), these being used to connect the means actuating the movement and the discs exerting the pushing or crushing of the sheets of paper. These pushing means can also have a piston shape.
  • The pushing or crushing means (6) are capable of sliding in the hollow channels (or cylinder) (15).
  • The pushing or stamping means (5) are advantageously cylinders, which can slide inside the pushing means (6). For quality and safety reasons, it is advantageous for these cylinders to have a rounded end, or even a spherical or ovoid end.
  • The means to avoid jamming of the paper are advantageously grooves or serrations or grooves arranged on the interior or exterior walls of the cylinders, in particular hollow channels (or cylinders) (15), pushing means (6), and means pushing (5), especially when these pushing means (5) and (6) are cylindrical. The size and shape of the grooves or grooves can vary widely without departing from the scope of the invention. Generally the size of these grooves or serrations or grooves are between 1/2 mm and 1 cm, but sizes exceeding these limits can also be used without departing from the scope of the invention. The grooves or serrations or grooves are advantageously arranged on more than half of the surface of the cylinders (hollow channels and pushing means), preferably on more than 2/3 of these surfaces, and even more preferably on all of these surfaces .
  • The means (56) allowing delayed pushing of the means (6) for pushing and crushing the lateral parts (16) and means (5) for pushing and stamping the centers of the small sheets, are advantageously constituted by springs (or a means equivalent) maintaining a spatial offset between the means (6) and the means (5). By actuating the pushing of the means (6), the means (5) which are held in an offset and advanced position, push the centers of the small sheets. When these means (5) abut against the rigid surfaces (4), then the means actuating the pushing of the pushing means (6) prevail over the springs [or means (56) maintaining the offset between (6) and (5)] and the pushing of the lateral parts (16) of the small sheets takes place after the pushing of the centers (1) of the small sheets.
  • In the foregoing, the delayed pushing of the means (6) and (5) has been presented as achieved by means of springs. Other systems can be used, in particular motors actuating the means (5) separately and successively then the means (6).

    • FIGURESFIGURES

    Des exemples particuliers de réalisation de l'invention sont illustrés dans les figures 1 à 9, ces exemples étant donnés à titre non limitatif et sans échelle déterminée, et simplement pour mieux faire comprendre l'invention.Specific examples of embodiment of the invention are illustrated in the Figures 1 to 9, these examples being given without limitation and without scale determined, and simply to better understand the invention.

    Les figure 6, 7, et 8 montrent une vue en perspective de trois pièces calantes variées. En périphérie on voit les parois (10) écrasées, et, au centre, le fond (9) de la cuvette.Figures 6, 7, and 8 show a perspective view of three wedging pieces varied. On the periphery we see the crushed walls (10), and, in the center, the bottom (9) of the bowl.

    La figure 1 représente les moyens de poussage (et emboutissage) (5) et les moyens de poussage et écrasement (6) avant poussage (ou emboutissage) des petites feuilles de papier (1). Les canaux creux (15) (ou cylindres) sont alors obturés à leurs deux extrémités (ou ouvertures) ; à une extrémité, ils sont obturés par les petites feuilles de papier (1) et à l'autre extrémité par les butoirs ou surfaces rigides (4). Les moyens d'éviter le coincement du papier existent, mais ne sont pas représentés. Le papier se déroule à partir d'un rouleau (12) ; des moyens (14) d'entraínement du papier font dérouler le papier et l'amènent vers les moyens de découpage (13) et de là, en face (1) des moyens de d'emboutissage (5). Les moyens (5) sont un mandrin et les moyens (6) sont un manchon. Figure 1 shows the pushing (and stamping) means (5) and the pushing and crushing means (6) before pushing (or stamping) small sheets of paper (1). The hollow channels (15) (or cylinders) are then closed at their two ends (or openings); at one end, they are closed by small sheets of paper (1) and at the other end by the bumpers or rigid surfaces (4). The Ways to avoid jamming of the paper exist, but are not shown. The paper is unwound from a roll (12); means (14) for driving the paper unroll the paper and bring it to the cutting means (13) and there, opposite (1) stamping means (5). The means (5) are a mandrel and the means (6) are a sleeve.

    La figure 2 représente le stade suivant du procédé de l'invention où les moyens de poussage ou mandrin (5) ont poussé la petite feuille (1) complètement à l'intérieur du cylindre creux (15), sans que cette petite feuille se coince entre le manchon (6) et le mandrin (5), et jusqu'à ce que cette petite feuille entre en contact avec (ou bute contre) le butoir ou surface rigide (4). La partie de la petite feuille (1) entrant en contact avec la surface rigide (4) est destinée à constituer le fond de la cuvette des pièces calantes selon l'invention. À ce stade du procédé, selon la figure 2, les moyens (6) n'ont pas encore poussé ou écrasé les parties latérales (16) des petites feuilles, car ils ont une action différée.FIG. 2 represents the next stage of the process of the invention where the means pushing device or mandrel (5) pushed the small sheet (1) completely inside of the hollow cylinder (15), without this small sheet getting caught between the sleeve (6) and the mandrel (5), and until this small sheet comes into contact with (or stops against) the stopper or rigid surface (4). The part of the small sheet (1) coming into contact with the rigid surface (4) is intended to constitute the bottom of the bowl of wedging parts according to the invention. At this stage of the process, according to FIG. 2, the means (6) have not yet pushed or crushed the lateral parts (16) of the small leaves, because they have a delayed action.

    La figure 3 représente le stade ultérieur du procédé de l'invention où les moyens de poussage ou manchon (6) ont poussé et écrasé les parties latérales (16) des petites feuilles (1) de papier. À ce stade, les pièces calantes (11) sont déjà formées [à partir des petites feuilles (1)], mais ne sont pas encore libérées de la machine.FIG. 3 represents the later stage of the process of the invention where the pushing means or sleeve (6) pushed and crushed the lateral parts (16) small sheets (1) of paper. At this point, the wedging pieces (11) are already formed [from small leaves (1)], but are not yet released from the machine.

    La figure 4 représente le stade suivant du procédé selon l'invention où les pièces calantes (11) sont libérées de la machine grâce au poussage des moyens d'emboutissage (5) et au retrait des butoirs ou surfaces rigides (4), ces pièces calantes (11) devant alors être réunies avec d'autres pièces calantes formées simultanément et/ou parallèlement, les unes et les autres étant alors collectées pour constituer le matériau de calage.FIG. 4 represents the next stage of the method according to the invention where the wedging parts (11) are released from the machine by the pushing of the means stamping (5) and removing the bumpers or rigid surfaces (4), these parts wedges (11) which must then be combined with other wedging parts formed simultaneously and / or in parallel, both then being collected for constitute the cushioning material.

    La figure 5 représente deux cylindres rainurés ou dentelés et coulissant, l'un intérieur (7) et l'autre extérieur (8). Si le cylindre intérieur (7) représente les moyens (6) de poussage (ou manchon), alors le cylindre extérieur (8) représente le canal (ou cylindre) creux (15). Si le cylindre intérieur (7) représente les moyens (5) de poussage (ou mandrin), alors le cylindre extérieur (8) représente les moyens (6) de poussage ou manchon.FIG. 5 represents two grooved or serrated and sliding cylinders, one inside (7) and the other outside (8). If the inner cylinder (7) represents the means (6) pushing (or sleeve), then the outer cylinder (8) represents the channel (or cylinder) hollow (15). If the inner cylinder (7) represents the means (5) of pushing (or mandrel), then the outer cylinder (8) represents the means (6) of push or sleeve.

    Les figures 6, 7 et 8 représentent des pièces calantes selon l'invention. On voit le fond (17) des pièces calantes. Un évidement central est entre les parois épaisses (18) ; la forme globale des pièces calantes est celle d'un godet ou cuvette à parois épaisses. Ces dessins font ressortir le caractère irrégulier des épaisseurs et des plissages des parois épaisses. Malgré les irrégularités d'épaisseur des parois épaisses, on peut déterminer une épaisseur approximative moyenne de ces parois épaisses ainsi qu'un diamètre interne et externe du cylindre ou tube des parois.Figures 6, 7 and 8 show wedging parts according to the invention. We see the bottom (17) of the wedging pieces. A central recess is between the thick walls (18); the overall shape of the wedging pieces is that of a bucket or bowl with walls thick. These drawings highlight the irregular character of the thicknesses and pleating of thick walls. Despite the thickness irregularities of the thick walls, we can determine an approximate average thickness of these thick walls as well an internal and external diameter of the cylinder or tube of the walls.

    La figure 7 se distingue par la hauteur plus basse du godet et sa forme un peu évasée au bas.Figure 7 is distinguished by the lower height of the bucket and its slightly flared at the bottom.

    La figure 8 se distingue par un diamètre global relativement large pour le godet.Figure 8 is distinguished by a relatively large overall diameter for the bucket.

    Ces pièces calantes peuvent être telles quelles, grandeur nature, mais des variations en plus ou en moins peuvent parfaitement être réalisées.These wedging pieces can be as is, life size, but more or less variations can be perfectly realized.

    Les plissements des parois sont très irréguliers : cela est du à l'effet de l'écrasement. Mais on peut néanmoins discerner une tendance à une orientation générale approximativement parallèle aux fonds des godets, l'écrasement ayant eu lieu approximativement perpendiculairement à ces fonds des godets.The folds of the walls are very irregular: this is due to the effect of crushing. But we can nevertheless discern a tendency to an orientation general approximately parallel to the bottoms of the buckets, the crushing having place approximately perpendicular to these bottoms of the buckets.

    La figure 9 illustre un emballage (19) contenant un objet (20) à emballer et calé par un matériau de calage selon l'invention, lui-même constitué d'une pluralité de pièces calantes (11). L'emballage final comprend un supplément de pièces calantes de manière à recouvrir entièrement l'objet à emballer.FIG. 9 illustrates a package (19) containing an object (20) to be packaged and wedged by a cushioning material according to the invention, itself made up of a plurality of wedging pieces (11). The final packaging includes an additional set of wedges so as to completely cover the object to be packaged.
