Description

La présente invention concerne le domaine des profilés d'accrochage ou de fermeture.The present invention relates to the field of fastening or closing profiles.

On utilise de tels profilés d'accrochage ou de fermeture dans différents domaines et notamment dans le domaine de l'affichage ou de la fabrication de housses pour la protection d'objets, ou encore d'une manière plus générale dans le domaine de la fabrication de sachets d'emballage.Such fastening or closing profiles are used in various fields and in particular in the field of the display or manufacture of covers for the protection of objects, or more generally in the field of manufacturing. packing bags.

En particulier dans le domaine de l'affichage, on utilise fréquemment des films support de publicité repliés sur eux-mêmes en boucle fermée et ainsi reliés, à leurs extrémités rendues adjacentes, par les éléments ou profilés d'accrochage précités. Ces films sont généralement entraînés à déplacement en regard d'une fenêtre pour modifier la plage d'informations ainsi rendue visible.Particularly in the field of the display, advertising support films folded on themselves in a closed loop are frequently used and thus connected, at their ends made adjacent, by the aforementioned elements or fastening profiles. These films are generally driven to move next to a window to change the range of information thus made visible.

Dans le domaine des sachets d'emballage il est connu d'équiper des films, au niveau de l'embouchure de sachets de profilés de fermeture permettant, par leur séparation, l'ouverture des sachets et un libre accès à leur contenu tout en autorisant une refermeture ultérieure.In the field of packaging bags, it is known to equip films at the mouth of sachets of closure profiles allowing, by their separation, the opening of the sachets and free access to their contents while allowing a subsequent reclosing.

Les éléments ou profilés d'accrochage ou de fermeture peuvent faire l'objet de nombreux modes de réalisation. Il peut s'agir de crochets complémentaires, de structures mâle/femelle complémentaires ou encore de systèmes type velours ou boucles/crochets, voire tout système équivalent.The elements or sections of attachment or closure can be subject to many embodiments. It may be complementary hooks, complementary male / female structures or velvet type systems or loops / hooks, or any equivalent system.

De tels profilés d'accrochage ou de fermeture sont généralement conditionnés sous forme d'une bande enroulée sur un mandrin support. L'un des problèmes posé lors d'une utilisation industrielle est celle du raccord entre la fin d'une telle réserve et le début d'une réserve suivante pour approvisionner une machine de production.Such fastening or closing profiles are generally packaged in the form of a strip wound on a support mandrel. One of the problems in industrial use is the connection between the end of such a supply and the beginning of a subsequent supply to supply a production machine.

Jusqu'ici, la technique traditionnelle de raccord entre deux réserves de profilés d'accrochage ou de fermeture consiste à relier les extrémités de deux profilés à l'aide d'une bande autocollante. Cette technique s'avère cependant délicate à réaliser. En effet, pour permettre un engagement correct sur la machine d'exploitation, il est nécessaire d'obtenir un alignement parfait entre les deux profilés. Par ailleurs, la bande autocollante ne doit pas faire obstacle au défilement. Il est donc souvent indispensable de retoucher par des coupes la bande autocollante avant d'autoriser l'acheminement.So far, the traditional technique of connection between two reserves of fastening or closing profiles is to connect the ends of two profiles with a tape adhesive. This technique is however difficult to achieve. Indeed, to allow a correct engagement on the operating machine, it is necessary to obtain a perfect alignment between the two profiles. Moreover, the self-adhesive tape should not hinder scrolling. It is therefore often necessary to retouch the adhesive tape with cuts before authorizing the transport.

Les moyens ainsi connus ne donnent donc pas totale satisfaction.The means thus known do not give total satisfaction.

On notera par ailleurs, que la technique connue précitée conduit souvent à une résistance à la traction faible.It will be noted, moreover, that the aforementioned known technique often leads to a low tensile strength.

Le document FR-A-2036112 décrit un procédé de production de fermetures à glissière sous forme de longueurs d'une chaîne continue de fermeture à curseur du type à spirales plastiques. Le procédé décrit consiste à détacher une succession de longueurs de fermeture à glissière à partir de la chaîne continue par des lignes de coupe transversales traversant les rubans et les spirales. Le procédé comprend une étape de chauffage des spirales plastiques afin de conserver les circonvolutions et éviter que les spirales plastiques ne se desserrent ou ne se détachent. Les fermetures à glissière obtenues grâce à ce procédé sont munies de prolongements usuels à leurs extrémités longitudinales.The document FR-A-2036112 discloses a method for producing slide fasteners in the form of lengths of a continuous spiral-type slider closure chain. The method described consists in detaching a succession of zipper lengths from the continuous chain by transverse cutting lines passing through the ribbons and spirals. The method comprises a step of heating the plastic spirals in order to preserve the convolutions and to prevent the plastic spirals from loosening or detaching. The zippers obtained by this method are provided with usual extensions at their longitudinal ends.

La présente invention a maintenant pour but de proposer de nouveaux moyens présentant des propriétés améliorées par rapport à l'état de l'art.It is now an object of the present invention to provide novel means having improved properties over the state of the art.

Ce but est atteint dans le cadre de la présente invention, grâce à un procédé de raccordement de deux ensembles de profilés de fermeture ou d'accrochage, qui comprend les étapes consistant à :

  • tailler les extrémités respectives des deux ensembles de sorte que chacun de ceux-ci présente deux éléments dont les bords extrêmes sont décalés relativement dans le sens longitudinal,
  • engager les extrémités de ces deux ensembles dans un guide comprenant des moyens d'alignement respectifs des deux ensembles tout en laissant accès à une partie au moins des zones superposées des deux ensembles, et
  • relier par soudure les extrémités adjacentes des deux ensembles ainsi positionnés.
This object is achieved in the context of the present invention, by means of a method of connecting two sets of closure or fastening profiles, which comprises the steps of:
  • cutting the respective ends of the two sets so that each of them has two elements whose extreme edges are offset relatively in the longitudinal direction,
  • engaging the ends of these two sets in a guide comprising respective alignment means of the two sets while leaving access to at least a portion of the superimposed areas of the two sets, and
  • connect by welding the adjacent ends of the two sets thus positioned.

La présente invention concerne également un guide pour la mise en oeuvre du procédé précité, comprenant des moyens d'alignement respectifs des deux ensembles tout en laissant accès à une partie au moins des zones superposées des deux ensembles.The present invention also relates to a guide for implementing the above method, comprising respective alignment means of the two sets while leaving access to at least a portion of the superimposed areas of the two sets.

Selon un mode de réalisation préférentiel, le guide précité comprend d'une part, une gorge longitudinale apte à recevoir en position d'alignement mutuel les moyens d'accrochage ou de fermeture desdits profilés et d'autre part, des lames encadrant cette gorge et adaptées pour prendre position entre des voiles support desdits ensembles.According to a preferred embodiment, the aforementioned guide comprises on the one hand, a longitudinal groove adapted to receive in mutual alignment position the attachment means or closure of said profiles and on the other hand, blades flanking the groove and adapted to take a position between support sails of said sets.

  • the figure 7 schematically represents a perspective view of two sets of closure profiles connected in accordance with the invention, and
  • the Figures 8 and 9 represent cross-sectional views of two variants of closure profiles that may be used in the context of the invention.

On aperçoit sur la figure 1 annexée, un guide formé d'une plaque rectiligne monobloc allongée 10.We can see on the figure 1 attached, a guide formed of an elongate monobloc rectilinear plate 10.

Typiquement, la plaque a une longueur de l'ordre de 10 à 15cm et une largeur de l'ordre de 1 à 2cm.Typically, the plate has a length of the order of 10 to 15 cm and a width of the order of 1 to 2 cm.

Selon le mode de réalisation représenté sur la figure 1, la plaque 10 est munie, au voisinage de l'une de ces extrémités d'un orifice ou oeillet traversant 12 destiné à faciliter sa manipulation et/ou son rangement par accrochage sur un support. Cependant, un tel orifice 12 n'intervient pas directement dans le processus de raccordement conforme à la présente invention.According to the embodiment shown on the figure 1 , the plate 10 is provided, in the vicinity of one of these ends of a hole or eyelet 12 through to facilitate its handling and / or storage by hanging on a support. However, such an orifice 12 does not intervene directly in the connection process according to the present invention.

Comme indiqué précédemment, la plaque 10 définit d'une part, une gorge longitudinale 20 apte à recevoir en position d'alignement mutuel les moyens d'accrochage ou de fermeture 112, 122 des profilés 110, 120 à raccorder et d'autre part, des lames 30, 32 encadrant cette gorge 20 et adaptées pour prendre position entre des voiles support 114, 124 desdits ensembles.As indicated above, the plate 10 defines on the one hand, a longitudinal groove 20 adapted to receive in the mutual alignment position the fastening or closing means 112, 122 of the profiles 110, 120 to be connected and on the other hand, blades 30, 32 flanking this groove 20 and adapted to take position between support webs 114, 124 of said sets.

Une telle gorge 20 et de telles lames 30, 32 peuvent faire l'objet de nombreux modes de réalisation.Such a groove 20 and such blades 30, 32 may be subject to many embodiments.

En pratique, comme illustré sur la figure 1, ces moyens sont réalisés à l'aide d'une découpe longitudinale dont la plaque 10 débouchant sur l'extrémité longitudinale de celle-ci opposée à l'oeillet 12.In practice, as illustrated on the figure 1 these means are made by means of a longitudinal cut, the plate 10 opening on the longitudinal end thereof opposite to the eyelet 12.

Plus précisément encore, selon le mode de réalisation préférentiel illustré sur la figure 1, la gorge 20 est formée par une fente rectiligne longitudinale formée à mi largeur dans la plaque 10. La largeur de cette fente formant la gorge 20 est complémentaire de la largeur des moyens de fermeture 112, 122. Elle est typiquement de l'ordre de quelques mm. Les deux lames 30, 32 sont formées de part et d'autre de la gorge 20. La fente formant la gorge 20 débouche sur l'extrémité longitudinale de la plaque 10 opposée à l'oeillet 12 sous forme d'une découpe évasée en dièdre concave délimité par deux arêtes rectilignes en V 31, 33 formant des biseaux en extrémité des lames 30, 32.More precisely still, according to the preferred embodiment illustrated on the figure 1 , the groove 20 is formed by a longitudinal rectilinear slot formed halfway in the plate 10. The width of this slot forming the groove 20 is complementary to the width of the closure means 112, 122. It is typically of the order of a few mm. The two blades 30, 32 are formed on either side of the groove 20. The slot forming the groove 20 opens on the longitudinal end of the plate 10 opposite the eyelet 12 in the form of a flared cutout dihedron concave delimited by two straight edges in V 31, 33 forming bevels at the end of the blades 30, 32.

Comme l'homme de l'art le comprendra, cette découpe évasée est destinée à faciliter l'engagement des profilés de fermeture.As those skilled in the art will understand, this flared cutout is intended to facilitate the engagement of closure profiles.

A son autre extrémité, dirigée vers le centre de la plaque 10, la fente formant la gorge 20 débouche dans une lumière oblongue 40 dont la plus grande extension s'étend transversalement par rapport à l'axe longitudinal de la plaque 10. Cette lumière oblongue 40 est destinée à recevoir l'un des ensembles. A cette fin, la longueur de la lumière 40 orientée transversalement par rapport à l'axe longitudinal de la plaque 10 est de préférence au moins égale à la largeur des voiles 114, 124 des ensembles de fermeture.At its other end, directed towards the center of the plate 10, the slot forming the groove 20 opens into an oblong slot 40 whose largest extension extends transversely with respect to the longitudinal axis of the plate 10. This oblong slot 40 is intended to receive one of the sets. For this purpose, the length of the light 40 oriented transversely to the longitudinal axis of the plate 10 is preferably at least equal to the width of the webs 114, 124 of the closure assemblies.

Typiquement, la lumière oblongue 40 a une longueur (transverse à l'axe longitudinal de la plaque 10) de l'ordre de 10 à 15mm, tandis que la largeur (parallèle à l'axe longitudinal de la plaque 10) est de l'ordre de 5mm.Typically, the oblong slot 40 has a length (transverse to the longitudinal axis of the plate 10) of the order of 10 to 15 mm, while the width (parallel to the longitudinal axis of the plate 10) is from order of 5mm.

La gorge 20 s'étend typiquement sur la moitié de la longueur de la plaque 10.The groove 20 typically extends over half the length of the plate 10.

La plaque 10 peut être réalisée en tout matériau approprié, par exemple en métal ou en matériaux thermoplastiques.The plate 10 can be made of any suitable material, for example metal or thermoplastic materials.

On va maintenant décrire le procédé de raccordement conforme à la présente invention.The connection method according to the present invention will now be described.

Comme montré sur la figure 2, la première étape consiste à découper les extrémités des deux ensembles à raccorder de sorte que chacun de ceux-ci possède deux éléments dont les extrémités respectives sont décalées relativement dans le sens longitudinal.As shown on the figure 2 the first step is to cut the ends of the two sets to be connected so that each of them has two elements whose respective ends are offset relatively in the longitudinal direction.

L'écart longitudinal entre les extrémités de ces deux éléments est typiquement de l'ordre de 1 à 5cm.The longitudinal gap between the ends of these two elements is typically of the order of 1 to 5 cm.

Dans le cas de profilés de fermeture type mâle/femelle, de préférence pour un premier ensemble l'élément de plus grande longueur est un élément femelle, tandis que pour le deuxième ensemble, l'élément de plus grande longueur est de type mâle complémentaire.In the case of closure profiles male / female type, preferably for a first set the longer element is a female element, while for the second set, the element of greater length is of complementary male type.

Sur la figure 2, de manière arbitraire, l'élément dont le voile est référencé 114 présente une longueur supérieure à l'élément dont le voile est référencé 124.On the figure 2 , arbitrarily, the element whose web is referenced 114 has a length greater than the element whose web is referenced 124.

Comme illustré sur les figures 3 et 4, les étapes ultérieures consistent à engager les deux ensembles sur le guide 10. Comme illustré sur la figure 3, l'un des ensembles est engagé par l'extrémité de la gorge 20 adjacente à la lumière 40. Pour cela, par exemple, le voile 114a de grande longueur est engagé dans la lumière 40 puis glissé en position sous-jacente aux lames 30, 32 tandis que le voile 124a de plus faible longueur est positionné au dessus de celles-ci.As illustrated on figures 3 and 4 , the subsequent steps are to engage the two sets on the guide 10. As illustrated on the figure 3 one of the assemblies is engaged by the end of the groove 20 adjacent to the light 40. For this, for example, the veil 114a of great length is engaged in the lumen 40 and then slid into the position underlying the blades 30 32 while the web 124a of shorter length is positioned above them.

Les moyens de fermeture 112a, 122a de ces éléments sont placés dans la gorge 20.The closure means 112a, 122a of these elements are placed in the groove 20.

Le deuxième ensemble est engagé sur le guide 10 par l'extrémité longitudinale de celui-ci. Le deuxième ensemble est inversé par rapport au premier. C'est-à-dire que si pour le premier ensemble le voile 114a de grande longueur est glissé en position sous-jacente aux lames 30, 32, inversement pour le deuxième ensemble le voile 114b de grande longueur est placé au dessus de celles-ci, tandis que le voile 124b de plus faible longueur est placé en position sous-jacente aux lames 30, 32.The second set is engaged on the guide 10 by the longitudinal end thereof. The second set is inverted with respect to the first. That is to say, if for the first assembly the veil 114a of great length is slid in the position underlying the blades 30, 32, conversely for the second set the veil 114b of great length is placed above those ci, while the veil 124b of shorter length is placed in position underlying the blades 30, 32.

Une fois les deux ensembles 100a, 100b rapprochés en position adjacentes par leurs extrémités, les deux voiles de grande longueur étant en partie superposés, il suffit comme illustré sur la figure 5 de procéder à une soudure des deux ensembles 100a, 100b pour relier ceux-ci.Once the two sets 100a, 100b close together in their adjacent position by their ends, the two long sails being partly superimposed, it is sufficient as illustrated on the figure 5 to weld the two sets 100a, 100b to connect them.

Il s'agit de préférence, d'une soudure par points 50 typiquement à l'aide d'une pointe chaude 60 et qui plus est au niveau des moyens de fermeture 114, 124 au niveau de la gorge 20. Dans ce cas, la gorge 20 évite tout débordement de la soudure.It is preferably a spot welding 50 typically using a hot tip 60 and moreover at the closing means 114, 124 at the groove 20. In this case, the groove 20 prevents overflow of the weld.

En variante, la soudure peut être automatisée avec une barre et des pointes.Alternatively, the weld can be automated with a bar and spikes.

Selon encore une autre variante, comme illustré sur la figure 6, les ensembles peuvent être fixés par soudure aux ultrasons au niveau de la gorge 20.According to yet another variant, as illustrated on the figure 6 , the sets can be fixed by ultrasonic welding at the groove 20.

La zone de soudure concerne de préférence les parties superposées des deux ensembles. Elle peut cependant également s'étendre en partie sur chacun de ces deux ensembles au delà des zones superposées précitées.The welding zone preferably relates to the superposed parts of the two sets. It may, however, also extend in part on each of these two sets beyond the aforementioned superimposed zones.

Selon encore une autre variante de réalisation, on peut envisager de souder également entre elles les extrémités transversales adjacentes des deux ensembles pour éviter tout accrochage de celles-ci lors du défilement ultérieur des profilés.According to yet another alternative embodiment, it may be envisaged to also weld together the adjacent transverse ends of the two assemblies to prevent them from being hooked up during the subsequent scrolling of the sections.

Il suffit alors de laisser l'ensemble se refroidir et de retirer le guide par déformation élastique des voiles 114, 124 pour disposer d'une bande continue de profilés.It is then sufficient to allow the assembly to cool and remove the guide by elastic deformation of the webs 114, 124 to have a continuous strip of profiles.

Le procédé conforme à la présente invention permet d'obtenir un assemblage présentant une résistance à la traction supérieure à l'état de l'art.The method according to the present invention provides an assembly having a tensile strength superior to the state of the art.

Les profilés d'accrochage ou de fermeture, susceptibles d'être utilisés dans le cadre de la présente invention, peuvent faire l'objet de toute variante appropriée. Il s'agit avantageusement de profilés en matériaux thermoplastiques, par exemple de polypropylène. Sur les figures 8 et 9 annexées, on a représenté des ensembles 100 comprenant deux éléments 110, 120 comportant respectivement des moyens de fermeture ou d'accrochage 112, 122 portés par des voiles 114, 124.The fastening or closing profiles, which may be used in the context of the present invention, may be the subject of any appropriate variant. It is advantageously of profiles in thermoplastic materials, for example polypropylene. On the Figures 8 and 9 attached, there is shown sets 100 comprising two elements 110, 120 respectively comprising closure means or attachment 112, 122 carried by webs 114, 124.

Leur configuration peut faire l'objet de diverses variantes de réalisation.Their configuration can be the subject of various embodiments.

On a représenté sur les figures 8 et 9, deux modes de réalisation préférentiels non limitatifs.We have shown on Figures 8 and 9 , two non-limiting preferred embodiments.
