Description

DISPOSITIF DE CONTRE-COLLAGE A LA FLAMME A TROIS CYLINDRES DE
PRESSION
La présente invention concerne le contre-collage à la flamme dans
lequel une premiére bande continue d'une mousse thermofusible est
déroulée continûment devant la flamme d'au moins un brflleur
faisant toute la largeur de la bande avant d'être appliquée sur
une seconde bande continue d'un matériau , par exemple textile,
moyennant quoi la partie superficielle thermofondue de la mousse
réalise le collage de la mousse sur le textile. Elle concerne plus
particulièrement un dispositif de contre-collage équipé de trois
cylindres de pression et de moyens de réglage desdits cylindres en
fonction des paramètres de fonctionnement du dispositif et
notamment de l'épaisseur de la mousse.THREE-CYLINDER FLAME LAMINATION DEVICE
PRESSURE
The present invention relates to flame lamination in
which a first continuous strip of hot melt foam is
unrolled continuously in front of the flame of at least one burner
making the entire width of the strip before being applied to
a second continuous strip of a material, for example textile,
whereby the thermofused surface portion of the foam
sticks the foam onto the textile. It concerns more
particularly a laminating device equipped with three
pressure cylinders and means for adjusting said cylinders
depending on the operating parameters of the device and
especially the thickness of the foam.

La technique de contre-collage à la flamme est bien
connue.L'installation pour sa mise en oeuvre comporte un certain
nombre de cylindres de pression délimitant le parcours d'une part
de la mousse de contre-collage et d'autre part du ou des
matériaux, par exemple textiles, destinés à être collés sur une
face ou sur les deux faces de la mousse. Elle comporte
également des brûleurs , généralement au nombre de deux , chacun tâtant monté transversalement et apte à produire une flamme à
proximité de la mousse lors de son déplacement continu sur toute
la largeur de celle-ci.The flame lamination technique is good
The installation for its implementation includes a certain
number of pressure cylinders delimiting the route on the one hand
lamination foam and on the other hand of the
materials, for example textiles, intended to be bonded to a
face or on both sides of the foam. It involves
also burners, generally two in number, each groping mounted transversely and capable of producing a flame at
proximity of the foam during its continuous movement over the entire
the width of it.

Dans les installations connues , les changements de
fabrication sont particulièrement complexes. Le cylindre de
pression situé dans la partie basse de l'installation présente un
diamètre important ; il est fixe en position. Lors d'un changement
de fabrication, il est nécessaire de modifier l'écartement entre
ce premier cylindre et le cylindre de pression intermédiaire et
aussi l'écartement entre le cylindre intermédiaire et le cylindre
de pression supérieur , ces trois cylindres délimitant le parcours
de la mousse et du ou des matériaux à contre-coller sur la mousse.In known installations, changes in
manufacturing are particularly complex. The cylinder of
pressure located in the lower part of the installation presents a
large diameter; it is fixed in position. During a change
of manufacturing, it is necessary to modify the spacing between
this first cylinder and the intermediate pressure cylinder and
also the distance between the intermediate cylinder and the cylinder
of higher pressure, these three cylinders delimiting the course
foam and material (s) to be laminated to the foam.

Ceci est obtenu par un démontage manuel des supports des arbres
des cylindres et par un ajustement adéquat de leur position. This is achieved by manual disassembly of the shaft supports
cylinders and by an adequate adjustment of their position.

Or on a trouve et c' est ce qui fait l'objet de l'invention un dispositif de contre-collage à la flamme qui pallie
l'inconvénient précité en ce que le réglage du cylindre de pression, lors du changement de fabrication , est réalisé de manière particulièrement simple et précise.Now we have found and this is what is the subject of the invention a device for flame bonding which overcomes
the aforementioned drawback in that the adjustment of the pressure cylinder, during the change of manufacture, is carried out in a particularly simple and precise manner.

Le dispositif comporte de manière connue trois cylindres de pression délimitant le parcours de la mousse de contre-collage et du ou des matériaux à contre-coller et deux brflleurs. Selon l'invention les axes des cylindres étant sensiblement dans le même plan vertical , le cylindre central est fixe et chacun des deux cylindres supérieur et inférieur est équipé de vérins, aptes à déplacer verticalement ledit cylindre entre deux positions : une première position dite de retrait par rapport au cylindre central et une seconde position dite de contact avec le cylindre central, et de butées, aptes à régler précisément le positionnement dudit cylindre par rapport au cylindre central dans la position de contact. The device comprises in known manner three pressure cylinders delimiting the path of the lamination foam and of the material (s) to be laminated and two burners. According to the invention the axes of the cylinders being substantially in the same vertical plane, the central cylinder is fixed and each of the two upper and lower cylinders is equipped with jacks, capable of vertically moving said cylinder between two positions: a first so-called withdrawal position relative to the central cylinder and a second position called contact with the central cylinder, and stops, capable of precisely adjusting the positioning of said cylinder relative to the central cylinder in the contact position.

De préférence le bâti , supportant les cylindres, comporte des logements pour des cales limitane la course des vérins . Ce sont ces cales qui font office de butées. Preferably the frame, supporting the cylinders, comprises housings for wedges limiting the stroke of the jacks. These wedges act as stops.

De préférence le dispositif comporte des moyens de commande, aptes à actionner selon un programme pré-établi les vérins des deux cylindres supérieur et inférieur, le moyen de déplacement et de fonctionnement des brûleurs et les moyens de rotation des cylindres de pression et de l'article contre-collé. Preferably, the device comprises control means, capable of actuating, according to a pre-established program, the jacks of the two upper and lower cylinders, the means for moving and operating the burners and the means for rotating the pressure cylinders and the laminated item.

D'autres avantages et caractéristiques ressortiront de la description qui va être faite d'un mode de réalisation d'un dispositif de contre-collage à la flamme à trois cylindres, donné à titre d'exemple non limitatif , illustré par le dessin annexé dans lequel
La figure unique est une représentation schématique de côté du dispositif.Other advantages and characteristics will emerge from the description which will be given of an embodiment of a flame lamination device with three cylinders, given by way of nonlimiting example, illustrated by the drawing appended in which
The single figure is a schematic side view of the device.

Le dispositif de contre-collage à la flamme comporte un bâti 1 dont on n'a représenté que la partie , fixée au sol 2, supportant à sa partie haute la hotte d'aspiration 6 et les trois cylindres de pression 3,4,5, respectivement le cylindre central 3 qui est fixe , le cylindre supérieur 4 mobile verticalement et le cylindre inférieur 5 mobile verticalement. Chaque cylindre est entraîné en rotation à la meme vitesse par des moyens non représentés, les cylindres supérieur 4 et inférieur 5 tournant dans le meme sens (flèche S) tandis que le cylindre central 3 tourne dans le sens inverse (flèche T). The flame lamination device comprises a frame 1 of which only the part, fixed to the ground 2, has been shown, supporting at its upper part the suction hood 6 and the three pressure cylinders 3,4,5 , respectively the central cylinder 3 which is fixed, the upper cylinder 4 movable vertically and the lower cylinder 5 movable vertically. Each cylinder is rotated at the same speed by means not shown, the upper 4 and lower 5 cylinders rotating in the same direction (arrow S) while the central cylinder 3 rotates in the opposite direction (arrow T).

Le bâti I comporte des montants verticaux, respectivement des montants avant 7, dans le sens du déplacement de l'article contre-collé 9 selon la flèche F, et des montants arrière 8. 125 montants 7,8 les plus extérieurs délimitent un volume ayant la forme d'un parallélépipède rectangle, à l'intérieur duquel sont placés les trois cylindres de pression 3,4 et 5, dont les axes de rotation, parallèles entre eux , sont orientés transversalement par rapport au déplacement de l'article 9. The frame I comprises vertical uprights, respectively front uprights 7, in the direction of movement of the laminated article 9 according to arrow F, and rear uprights 8. 125 outermost 7.8 uprights define a volume having the shape of a rectangular parallelepiped, inside which are placed the three pressure cylinders 3,4 and 5, whose axes of rotation, parallel to each other, are oriented transversely to the displacement of the article 9.

Les montants 7,8 , correspondant à un meme côté du dispositif , sont reliés par trois traverses 10,11 et 12. Sur la traverse centrale 10 est monté le palier 13 de roulement de l'axe 17 de rotation du cylindre central 3. Le cylindre 3,maintenu de chaque coté par des palier 13,est fi;9 en position. The uprights 7,8, corresponding to the same side of the device, are connected by three crosspieces 10, 11 and 12. On the central crosspiece 10 is mounted the bearing 13 for rolling the axis 17 of rotation of the central cylinder 3. The cylinder 3, held on each side by bearings 13, is fi; 9 in position.

Sur la traverse supérieure 11 est fixé le vérin 14 dont la tige 15 est terminée par un cadre 16 dans lequel est monté le palier 18 de roulement de l'axe 19 de rotation du cylindre supérieur 4. On the upper cross member 11 is fixed the jack 14 whose rod 15 is terminated by a frame 16 in which is mounted the bearing 18 for rolling the axis 19 of rotation of the upper cylinder 4.

Sur la traverse inférieure 12 est fixé le vérin 20 dont la tige 21 est terminée par un cadre 22 dans lequel est monté le palier 23 de roulement de l'axe 24 de rotation du cylindre inférieur 5. On the lower cross member 12 is fixed the jack 20 whose rod 21 is terminated by a frame 22 in which is mounted the bearing 23 for rolling the axis 24 of rotation of the lower cylinder 5.

De part et d'autre du b ti 1 sont prévus des moyens d'alimentation en mousse 25 et en tissu 26 et 27 à contre-coller sur la mousse 25, ainsi que des moyens de réception de l'article contre-collé 9. On either side of the b ti 1 are provided means for supplying foam 25 and fabric 26 and 27 to be laminated to the foam 25, as well as means for receiving the laminated article 9.

Ces moyens , qui sont usuels dans l'industrie textile, consistent dans des barres respectivement 29,30,31,32 sur lesquelles sont enfilés les tubes de support de la mousse 25 , des tissus 26 et 27 et de l'article contre-collé 9, seule la dernière barre 32 étant mue en rotation pour entraîner l'article contre-collé 9 dans le sens de la flèche F. These means, which are usual in the textile industry, consist of bars respectively 29,30,31,32 on which are threaded the tubes for supporting the foam 25, the fabrics 26 and 27 and the laminated article 9, only the last bar 32 being rotated to drive the laminated article 9 in the direction of the arrow F.

Sur le parcours de la mousse 25, des tissus 26,27 et de l'article contre-collé 9 sont placées des barres de détour afin de régulariser la tension. Along the course of the foam 25, fabrics 26, 27 and of the laminated article 9 are placed detour bars in order to regulate the tension.

De part et d'autre du bati 1 sont montés deux broyeurs 28 et 33 . Chaque brûleur 28 est constitué d'une enceinte 34 de répartition du gaz à briller et d'une tête de flambage 35, par laquelle le gaz s'échappe et est enflammé. La tête de flambage 35 est parallèle aux cylindres de pression ; sa longueur est sensiblement la meme que celle desdits cylindres. L'enceinte 34 de répartition de chaque brûleur 28,33 est raccordée par au moins une conduite à une alimentation en gaz ou en mélangeair-gaz approprié au flambage. On both sides of the frame 1 are mounted two grinders 28 and 33. Each burner 28 consists of an enclosure 34 for distributing the gas to be shined and a flaming head 35, through which the gas escapes and is ignited. The buckling head 35 is parallel to the pressure cylinders; its length is substantially the same as that of said cylinders. The enclosure 34 for distributing each burner 28, 33 is connected by at least one pipe to a gas or air-gas mixture suitable for buckling.

Le premier brûleur 28 est situé à proximité de la partie basse du cylindre supérieur 4, sa tete de flambage 35 étant dirigée vers celui-ci. Il est , sur la figure, à droite du bâti 1, c'est-à-dire du côté où sont situées l'alimentation du tissu 27 et la réception de l'article contre-collé 9. The first burner 28 is located near the lower part of the upper cylinder 4, its buckling head 35 being directed towards the latter. It is, in the figure, to the right of the frame 1, that is to say on the side where the supply of the fabric 27 and the reception of the laminated article 9 are located.

Le second brûleur 33 est situé à proximité de la partie basse du cylindre central 3. Il est, sur la figure, à gauche du bâti 1, c'est-à-dire du côté où est située l'alimentation de la mousse 25 et du tissu 26. The second burner 33 is located near the lower part of the central cylinder 3. It is, in the figure, to the left of the frame 1, that is to say on the side where the supply of the foam 25 is located and fabric 26.

On a représenté par des flèches sur les tracés représentant la mousse 25, les tissus 26,27 et l'article contre-collé 9 ,la direction prise par chacun de ces éléments au cours du fonctionnement du dispositif, pour la réalisation d'un article 9 composé d'une mousse 25 sur chaque face de laquelle est contre-collé un tissu respectivement 25,26. The directions taken by each of these elements during the operation of the device, for the production of an article, have been represented by arrows on the lines representing the foam 25, the fabrics 26, 27 and the laminated article 9. 9 composed of a foam 25 on each face of which a fabric 25.26 is laminated respectively.

Le contre-collage est réalisé de la manière suivante. La mousse 25 s'enroule successivement sur une portion de la périphérie du cylindre supérieur 4, du cylindre central 3 et du cylindre inférieur 5, étant entraînée par la rotation de ces trois cylindres. Le brûleur 28 étant allumé, la flamme sortant de la tête de flambage 35 correspondante porte à l'état thermoplastique une certaine quantité du matériau constituant la mousse en regard de ladite tête de flambage 35. Le tissu 27 est enroulé autour du cylindre central 3 puis du cylindre inférieur 5. Il pénètre sur le cylindre central 3 à proximité immédiate de la ligne de pression entre le cylindre supérieur 4 et le cylindre central 3. Dans cette zone, la partie de la mousse 25 à l'état thermoplastique est comprimée sur le tissu 27, réalisant de ce fait le contre-collage de ce tissu 27 sur la mousse 25. Laminating is carried out as follows. The foam 25 is wound successively over a portion of the periphery of the upper cylinder 4, of the central cylinder 3 and of the lower cylinder 5, being driven by the rotation of these three cylinders. The burner 28 being lit, the flame emerging from the corresponding buckling head 35 carries in the thermoplastic state a certain amount of the material constituting the foam opposite said buckling head 35. The fabric 27 is wound around the central cylinder 3 then of the lower cylinder 5. It enters the central cylinder 3 in the immediate vicinity of the pressure line between the upper cylinder 4 and the central cylinder 3. In this zone, the part of the foam 25 in the thermoplastic state is compressed on the fabric 27, thereby realizing the lamination of this fabric 27 on the foam 25.

Il en est de même pour le second brûleur 33, portant à un état thermoplastique une certaine quantité du matériau constituant l'autre face de la mousse 25. Cette partie est comprimée sur le tissu 25 lors de leur passage entre le cylindre central 3 et le cylindre inférieur 5. Ainsi après son passage entre les trois cylindres , la mousse 25 est collée par chacune de ses deux faces sur les deux tissus 27 et 26 et constitue l'article contre-collé 9. It is the same for the second burner 33, bringing to a thermoplastic state a certain amount of the material constituting the other face of the foam 25. This part is compressed on the fabric 25 during their passage between the central cylinder 3 and the lower cylinder 5. Thus after its passage between the three cylinders, the foam 25 is bonded by each of its two faces to the two fabrics 27 and 26 and constitutes the laminated article 9.

Les moyens de réglage du positionnement relatif des cylindres supérieur 4 et inférieur 5 par rapport au cylindre central 3 consistent en deux cales 34,35 placées dans des logements faisant face aux cadres 16,22 lors de leur déplacement. The means for adjusting the relative positioning of the upper 4 and lower 5 cylinders relative to the central cylinder 3 consist of two wedges 34, 35 placed in housings facing the frames 16, 22 during their movement.

Un logement comprend une traverse 36 montée entre les deux montants 7,8 et formant le fond du logement et, au moins pour le logement inférieur correspondant au cadre 22 , deux portions 37,38 de traverse montées sur l'un 7 et l'autre 8 montants. Ces deux portions de traverse 37,38 maintiennent la cale 35 dans son logement, lorsque la tige 21 du vérin 20 est rentrée. La dimension du logement est telle qu'il est possible d'y introduire des cales 34,35 de différentes épaisseurs de manière à régler la course correspondante du vérin et donc la force de compression des cylindres sur la mousse en fonction des paramètres de fonctionnement du dispositif et en particulier de l'épaisseur de la mousse 25. Les cales 34,35 placées dans le logement forment butée pour les cadres 16,22 qui se déplacent verticalement entre les deux portions de traverse (37,38) , règlent la position relative des cylindres supérieur 4 et inférieur 5 par rapport au cylindre central 3, et par conséquent l'écartement entre ceux-ci.A housing comprises a crosspiece 36 mounted between the two uprights 7,8 and forming the bottom of the housing and, at least for the lower housing corresponding to the frame 22, two portions 37,38 of the crossmember mounted on one 7 and the other 8 uprights. These two cross-section portions 37, 38 hold the shim 35 in its housing when the rod 21 of the jack 20 is retracted. The size of the housing is such that it is possible to introduce shims 34, 35 of different thicknesses so as to adjust the corresponding stroke of the jack and therefore the compression force of the cylinders on the foam as a function of the operating parameters of the device and in particular of the thickness of the foam 25. The shims 34.35 placed in the housing form a stop for the frames 16.22 which move vertically between the two cross-section portions (37.38), regulate the relative position upper 4 and lower 5 cylinders relative to the central cylinder 3, and consequently the spacing between them.

En fonction de la force de collage souhaitée , le réglage correspond généralement à un écrasement de la mousse de 1 à 2 mm, c'est-à-dire que l'épaisseur des cales est choisie en sorte que la valeur de l'écartement entre les cylindres soit inférieure à l'épaisseur de la mousse 25 de 1 à 2 mm. Depending on the desired bonding force, the setting generally corresponds to a crushing of the foam of 1 to 2 mm, that is to say that the thickness of the shims is chosen so that the value of the spacing between the cylinders is less than the thickness of the foam 25 by 1 to 2 mm.

On comprend que pour l'introduction de la mousse 25 et des tissus 26,27 , les cylindres supérieur 4 et inférieur 5 doivent être écartés du cylindre central 3, les tiges 15,21 des vérins
14,20 étant rentrées...It is understood that for the introduction of the foam 25 and of the fabrics 26, 27, the upper 4 and lower 5 cylinders must be separated from the central cylinder 3, the rods 15, 21 of the jacks
14.20 having returned ...

Le dispositif comprend aussi des moyens de commande, non représentés sur la figure , assurant la commande synchronisée de tous les organes du dispositif selon un programme pré-établi lors du démarrage et de l'arrêt de l'opération de contre-collage. The device also includes control means, not shown in the figure, ensuring the synchronized control of all the organs of the device according to a pre-established program when starting and stopping the laminating operation.

Une fois la mousse introduite autour des cylindres et les tissus positionnés sur la face correspondante de la mousse grâce par exemple à un ruban adhésif, le démarrage s'effectue par la commande simultanée des vérins 14,20 , le déplacement des brûleurs 28,33 d'une position de retrait à la position de flambage et la rotation des axes 17,19,24 des cylindres de pression et de l'arbre 32 de réception de l'article contre-collé S
Dans l'exemple ci-dessus décrit de réalisation, les cylindres de pression avaient un meme diamètre de 200 mm.Once the foam has been introduced around the cylinders and the fabrics positioned on the corresponding face of the foam, for example by means of an adhesive tape, the start-up is carried out by the simultaneous control of the jacks 14, 20, the displacement of the burners 28.33 d 'a position of withdrawal to the position of buckling and the rotation of the axes 17,19,24 of the pressure cylinders and of the shaft 32 for receiving the laminated article S
In the example described above of embodiment, the pressure cylinders had the same diameter of 200 mm.

L'invention n'est pas limitée au mode de réalisation qui a été décrit à titre d'exemple non exhaustif , mais en couvre toutes les variantes. Bien sOr elle s'applique aussi au contre-collage une seule face , et non uniquement au contre-collage double face décrit ci-dessus.  The invention is not limited to the embodiment which has been described by way of non-exhaustive example, but covers all variants thereof. Of course, it also applies to single-sided lamination, and not only to double-sided lamination described above.
