Abstract
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.
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 materials and packing and filling 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 opening angle of the cone 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 more or less overlap 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 base pour le préambule de la revendication 1 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 base for the preamble of claim 1 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.
Le brevet US-A-2 685 827 décrit également des éléments de papier en forme de cuvette avec un plissage ; en outre un écrasement de ces élements est décrit (figure 5), mais l'écrasement fait disparaítre la forme de cuvette ou godet des éléments de papier.US-A-2,685,827 also describes elements of paper in the form of bowl with pleating; furthermore a crushing of these elements is described (Figure 5), but the crushing disappears the shape of bowl or bucket of the elements of paper.
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 filling elements in the shape of a thimble 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 to the 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.
Un but de la présente invention est de fournir un matériau de calage et remplissage d'emballage, évitant autant que possible les inconvénients des matériaux connus.An object of the present invention is to provide a cushioning material and packing filling, avoiding as much as possible the disadvantages of the materials known.
Un autre but de la présente invention est de fournir un matériau de calage et remplissage économique, peu coûteux, et facile à produire par des entreprises non spécialisées.Another object of the present invention is to provide a cushioning material and economical filling, inexpensive, and easy to produce by non- specialized.

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 form of hollow cylinder, thick-walled, 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 favors 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 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.
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 setting material as well as a machine intended to implement this process.
Le procédé selon l'invention est un procédé pour fabriquer un matériau de
calage et/ou remplissage d'emballage comprenant les étapes
suivantes :
L'écrasement étant opéré pendant que le moyen d'emboutissage reste , après emboutissage, dans le canal creux de la matrice, et définit dans cette position, avec la paroi intérieure du canal creux, un espace tubulaire apte à loger les parois latérales des cuvettes préliminaires et à recevoir les moyens d'écrasement.The crushing being operated while the stamping means remains, after stamping, in the hollow channel of the matrix, and defines in this position, with the inner wall of the hollow channel, a tubular space able to accommodate the side walls of the preliminary basins and to receive the crushing means.
Des aspects préférés du procédé selon l'invention sont les suivants, pris
séparément ou en combinaison :
Selon une modalité plus particulière du procédé selon l'invention, celui-ci
consiste à :
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 in 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.
Par ailleurs, l'invention concerne également une machine destinée à mettre en oeuvre le procédé selon l'invention. Les éléments de cette machine sont numérotés dans la description qui suit en utilisant les numéros des figures 1 à 5, étant entendu que la description suivante de la dite machine (et les revendications correspondantes) doit être comprise sans la mention de ces numéros, ceux-ci ne faisant pas partie de la description de la machine proprement dit et n'ayant qu'un rôle de faciliter la compréhension du texte.Furthermore, the invention also relates to a machine intended for setting up implements the method according to the invention. The elements of this machine are numbered in the following description using the numbers in FIGS. 1 to 5, it being understood as the following description of the said machine (and the corresponding claims) must be understood without the mention of these numbers, they are not part of the description of the machine itself and having only one role to facilitate the understanding of the text.
Cette machine pour la fabrication de matériau de calage et/ou remplissage d'emballage, est caractérisée en ce qu'elle comprend
En outre la machine selon l'invention comporte l'une ou l'autre des
caractéristiques suivantes préférentielles, prises isolément ou en combinaison :
Selon une autre manière d'exprimer l'invention relative à la machine, celle-ci
comprend
De manière avantageuse, les moyens (59) d'alimentation en petite feuille de
papier, comprennent en outre,
Dans la machine de l'invention, les moyens de poussage ou emboutissage sont aussi pourvus de moyens actionnant ce poussage ou emboutissage.In the machine of the invention, the pushing or drawing means are also provided with means actuating this pushing or stamping.
De manière encore avantageuse, la machine de l'invention comprend :
Plus précisément, les moyens sus-décrits peuvent être réalisés de la manière suivante :More specifically, the means described above can be achieved in the manner next :
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.As already said about the process, 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 base or polygonal, regular or irregular.
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.The pushing or crushing means (6) can be in the form of cylinders, or discs (i.e. 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 means of pushing can also have a piston shape.
Les moyens de poussage ou écrasement (6) sont capables de coulisser dans les canaux (ou cylindre) creux (15).The pushing or crushing means (6) are capable of sliding in the hollow channels (or cylinder) (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.The pushing or stamping means (5) are advantageously cylinders, which can slide inside the pushing means (6). For some reasons of quality and safety, it is advantageous that these cylinders have a tip rounded, even spherical or ovoid.
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. The means to avoid jamming of paper are advantageously grooves or serrations or grooves arranged on the interior walls or exterior of the cylinders, in particular hollow channels (or cylinders) (15), pushing means (6), and pushing means (5), in particular 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 included between 1/2 mm and 1 cm, but sizes exceeding these limits can also be used without departing from the scope of the invention. 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.
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.The means (56) allowing delayed pushing of the pushing means (6) and crushing of the lateral parts (16) and of the means (5) for pushing and stamping centers of the small leaves, are advantageously constituted by springs (or equivalent means) 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 maintained in an offset and advanced position, push the centers of the small leaves. When these means (5) abut against the rigid surfaces (4), then the means actuating the pushing means (6) prevail over the springs [or means (56) maintaining the offset between (6) and (5)] and the pushing of the parts lateral (16) of the small leaves is implemented after the pushing of centers (1) of small leaves.
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).In the above, the delayed pushing of 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).
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.
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). Un tel emballage fait aussi partie de l'invention. 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 chocks (11). Such packaging is also part of the invention. The final packaging includes a supplement of wedging parts so as to completely cover the object to be packaged.
