Description

Dispositif pour le pliage en zig-zag d'une bande  Device for zigzag folding of a strip
L'invention se rattache au secteur technique des machines et matériels de conditionnement de bandes flexibles en matériau textile du type rubans et produits similaires. The invention relates to the technical sector of machines and equipment for packaging flexible bands of textile material of the ribbons type and similar products.
Il est tout d'abord rappelé que les rubans et bandes textiles sont conditionnés en emballages et sont présentés avec une alternance de plis en zig zag,  It is first of all recalled that the ribbons and textile bands are conditioned in packaging and are presented with alternating pleats in zig zag,
Pour ce faire, on prévoit un dispositif comprenant un entablement agencé avec une zone arrière recevant des moyens de distribution de la bande fabriquée, une zone centrale agencée avec une fente transversale autorisant le déplacement alternatif d'un couple de galets entre lesquels est guidée la bande, les galets étant disposés sur un chariot animé par des moyens de commande d'un mouvement transversal alternatif en regard de la fente précitée et autorisant à la sortie des galets la mise en pli du ruban, ledit entablement présentant une zone avant autorisant la réception et l'évacuation des parties de ruban plié en continu et leur évacuation vers la zone de conditionnement. Il est en outre prévu des moyens de poussée des parties de bandes ou rubans pliées.  To do this, a device is provided comprising an entablature arranged with a rear zone receiving means for dispensing the fabricated strip, a central zone arranged with a transverse slot allowing the alternating movement of a pair of rollers between which the strip is guided. , the rollers being arranged on a carriage driven by means of controlling an alternating transverse movement opposite the aforementioned slot and authorizing, at the exit of the rollers, the folding of the ribbon, said entablature having a front zone authorizing reception and the evacuation of the continuously folded ribbon parts and their evacuation to the packaging area. Means are also provided for pushing the portions of folded strips or ribbons.
Dans une mise en oeuvre particulière. le déposant de la présente demande a proposé un dispositif perfectionné comprenant deux particularités définies dans le brevet français n° 88.12709.  In a particular implementation. the applicant of the present application has proposed an improved device comprising two features defined in French patent n ° 88.12709.
La première consiste â rendre positif alternativement chacun des galets en respectant le sens de défilement de la bande quel que soit le sens de déplacement du chariot, A cet effet, les galets sont sollicités en mouvement par des roues libres montées en opposition. La seconde particularité consiste à agir par des moyens contre les brins de la partie de bande en regard â la sortie du couple de galets en assurant une mise en pression et en tension alternée de chacune des demi-parties de bandes venant d'être exécutée pour maintenir à la verticale les parties de bandes pliées. Les moyens précités sont du type à courroies. The first consists in making each of the rollers alternately positive while respecting the direction of travel of the strip whatever the direction of movement of the carriage. To this end, the rollers are stressed in movement by free wheels mounted in opposition. The second feature consists in acting by means against the strands of the strip part opposite the output of the pair of rollers by ensuring a pressurization and alternating tension of each of the half-parts of strips just executed for keep the folded strip parts vertical. The aforementioned means are of the belt type.
Dans le cadre de l'exploitation du brevet précité qui s'avère tout à fait satisfaisante pour la majorité des bandes et rubans traités, on s'est aperçu que certains types de rubans avaient tendance à se déplier ces rubans ayant une certaine "nervosité", c'est-à-dire tendance à se détendre et ainsi constituer une gêne à la mise en oeuvre du conditionnement. Il était donc nécessaire d'améliorer le dispositif pour le rendre apte à répondre à ce problème,  In the context of the exploitation of the aforementioned patent which proves to be entirely satisfactory for the majority of the bands and ribbons treated, it has been observed that certain types of ribbons tend to unfold, these ribbons having a certain "nervousness" , that is to say a tendency to relax and thus constitute a hindrance to the implementation of the packaging. It was therefore necessary to improve the device to make it capable of responding to this problem,
En outre, en l'état de conception des galets, les dispositifs utilisés présentaient certaines limites dans les conditions de traitement des bandes ou rubans avec une largeur limitée.  In addition, in the design state of the rollers, the devices used had certain limits in the conditions of treatment of bands or ribbons with a limited width.
Un premier but recherché selon l'invention était donc d'améliorer les dispositifs existants en permettant une adaptation rapide des galets quelles que soient les dimensions en largeur des bandes ou rubans traités.  A first aim sought after according to the invention was therefore to improve the existing devices by allowing rapid adaptation of the rollers whatever the width dimensions of the bands or ribbons treated.
Un autre but recherché selon l'invention était de pouvoir utiliser le dispositif pour le pliage en zig zag de bandes ou rubans quelles que soient leurs types de constitution et leurs applications,  Another aim sought after according to the invention was to be able to use the device for the zig zag folding of bands or ribbons whatever their types of constitution and their applications,
Un autre but recherché selon l'invention était d'améliorer les dispositifs existant par l'utilisation de moyens complémentaires modulaires à montage et démontage rapide avec une très large capacité d'adaptation en remplissant les conditions de tenue des rubans ou bandes en vue d'un conditionnement parfait, Another aim sought after according to the invention was to improve the existing devices by the use of complementary modular means for rapid assembly and disassembly with a very large adaptability by fulfilling the conditions of holding ribbons or bands for perfect packaging,
Ces buts et d'autres encore ressortiront bien de la suite de la description.  These and other objects will become apparent from the following description.

The central or substantially entablature part is arranged with a transverse slot (3) allowing the alternating movement of a pair of rollers "(4) and (5), mounted in opposite rotation and between which the end of the tape or ribbon R, which is then zig zag folded.
Les moyens moteurs autorisant le déplacement transversal du chariot support (7) du couple de galets (4 et 5) sont disposés dans la partie inférieure de l'entablement et protégés par des plaques de protection, tandis que les galets se trouvent dans le plan supérieur de l'entablement.  The drive means allowing the transverse movement of the support carriage (7) of the pair of rollers (4 and 5) are arranged in the lower part of the entablature and protected by protective plates, while the rollers are in the upper plane entablature.
Afin d'assurer ledit mouvement, le chariot est associé par sa partie inférieure à des moyens de commande appropriés connus et pouvant, par exemple, et non limitativement, être constitués par un système de bielles ou manivelles commandés par un moteur, assurant le mouvement, de va et vient précité, ainsi qu'il apparait de manière schématique figure 3 ; ces moyens étaient décrits dans le brevet français précité.  In order to ensure said movement, the carriage is associated by its lower part with known suitable control means and which can, for example, and without limitation, be constituted by a system of connecting rods or cranks controlled by a motor, ensuring movement, back and forth above, as shown schematically in Figure 3; these means were described in the aforementioned French patent.
L'amplitude de déplacement du chariot est réglable de manière connue et est fonction de la longueur des plis de bandes ou rubans à obtenir.  The amplitude of movement of the carriage is adjustable in a known manner and is a function of the length of the folds of bands or ribbons to be obtained.
Suite au mouvement alterné du chariot support, la bande pliée est alors acheminée sur la partie avant de l'entablement en étant guidée longitudinalement par des profilés (6) fixés de toute manière appropriée. Ainsi au fur et à mesure du pliage de la bande, celle- ci est acheminée vers l'avant de l'entablement et tombe dans un emballage ou conditionnement prévu à cet effet et non illustré.  Following the alternating movement of the support carriage, the folded strip is then conveyed on the front part of the entablature, being guided longitudinally by profiles (6) fixed in any suitable manner. Thus, as the strip is folded, it is conveyed towards the front of the entablature and falls into a wrapping or packaging provided for this purpose and not illustrated.
Les galets (4) (5) sont animés d'un mouvement en rotation sur eux-mêmes selon le sens de déplacement du chariot. Dans une première mise en oeuvre spécifique non limitative décrite dans le brevet français n° 88.12709, les galets (4, 5) sont rendus positifs alternativement quelque soit le sens de déplacement du chariot et ce par des moyens du type roues libres (8, 9) associées au montage desdits galets, The rollers (4) (5) are rotated on themselves according to the direction of movement of the carriage. In a first specific implementation without limitation described in French patent n ° 88.12709, the rollers (4, 5) are made alternately positive whatever the direction of movement of the carriage and this by means of the type freewheels (8, 9) associated with the mounting of said rollers,
Par ailleurs et de manière connue, le dispositif comprend une courroie agissant pendant la mise en forme de plis de bandes ou rubans alternativement selon la position du chariot et donc des galets (4, 5) sur les parties de bandes ou rubans précités. Cette action Consiste dans l'exercice d'une pression et d'une poussée temporaire contre la partiedu ruban mise en pli et accompagnant le sens de défilement du chariot,  Furthermore and in known manner, the device comprises a belt acting during the shaping of folds of bands or ribbons alternately according to the position of the carriage and therefore of the rollers (4, 5) on the parts of the aforementioned bands or ribbons. This action consists in exerting a pressure and a temporary push against the part of the ribbon being folded and accompanying the direction of travel of the carriage,
Il convient dès lors d'exposer les caractéristiques de l'invention en se rapportant aux figures des dessins,  The characteristics of the invention should therefore be explained with reference to the figures in the drawings,
Le dispositif est tout d'abord remarquable par la conception nouvelle des galets (4 et 5) qui peuvent être entrainés positivement à l'aide de roues libres selon le brevet n° 88.12709 ou de toute autre manière.  The device is first of all remarkable for the new design of the rollers (4 and 5) which can be driven positively by means of freewheels according to patent No. 88.12709 or in any other way.
Ainsi, les galets référencés dans leur ensemblepar (4, 5) sont montés sur des axes (10) ou tiges de liaison et de guidage dont les extrémités inférieures sont fixées par des moyens appropriés à la structure support (11) référencée dans son ensemble, associée au chariot (7). Ces moyens de liaison sont par exempleceux décrits dans le brevet français précité, ou autres.  Thus, the rollers referenced as a whole by (4, 5) are mounted on pins (10) or connecting and guiding rods whose lower ends are fixed by means suitable for the support structure (11) referenced as a whole, associated with the carriage (7). These connecting means are for example those described in the aforementioned French patent, or others.
L'originalité des galets réside en ce qu'il sont constitués par une succession alternée de disques (12) et de poulies (13) réceptrices de câbles (14),une pluralité de poulies engendre une pluralité de câbles (14) dont l'ensemble constitue la ou les courroies (15) de poussée des parties de bandes ou rubans. Ainsi qu'il apparaît par exemple à la figure 4, les axes ou tiges de liaison (10) présentent â leur base epaulernent inférieur (10.1) autorisant le centrage et l'appui de l'un des éléments constitutifs des galets et par exemple une poulie. The originality of the rollers lies in that they consist of an alternating succession of discs (12) and pulleys (13) receiving cables (14), a plurality of pulleys generates a plurality of cables (14), the together constitutes the pushing belt or belts (15) of the parts of bands or tapes. As it appears for example in Figure 4, the pins or connecting rods (10) have at their lower epaulernent base (10.1) allowing the centering and support of one of the constituent elements of the rollers and for example a pulley.
Ensuite à la manière d'un jeu de construction, les disques et poulies sont montées alternativement sur l'axe avec des moyens mécaniques du type rondelles (16) ou équivallent, pour permettre l'indépendance du mouvement des poulies en égard des disques, Ainsi qu'il apparait aux dessins les disques reçoivent à leur périphérie une couronne (17) en matériau souple et adhérent. Tous les disques et couronnes associés définissent une génératrice commune verticale et lorsque les deux galets (4, 5) sont ainsi montés, ils ne permettent le passage que de la bande ou ruban qui est entrainé par leur mouvement en rotation. Les Pθulies (13) sont de diamètre plus réduit que les disques (12) et couronnes associées de telle sorte que les câbles (14) se situent à l'intérieur du volume de chaque galet,  Then in the manner of a construction game, the discs and pulleys are mounted alternately on the axis with mechanical means of the washer type (16) or equivalent, to allow the independence of the movement of the pulleys with regard to the discs, Thus as it appears in the drawings, the discs receive at their periphery a crown (17) made of flexible and adherent material. All the associated discs and crowns define a common vertical generator and when the two rollers (4, 5) are thus mounted, they only allow the passage of the strip or ribbon which is driven by their rotary movement. The Pθulies (13) are of smaller diameter than the discs (12) and associated crowns so that the cables (14) are located inside the volume of each roller,
Le montage sur les axes (10) des éléments modulai res constituant les galets peut s'effectuer par tous moyens mécaniques connus tout en conservant le même concept de réalisation. On a par exemple illustré figure 11 une mise en oeuvre possible de montage. On utilise par exemple deux couples de bagues (18-19) qui sont montées alternativement sur les axes ou tiges de liaison (10), Ces bagues (18-19) sont agencées et épaulées pour recevoir au moins une couronne (17) en matériau souple et au moins une poulie (13) d'entrainement des câbles.  The mounting on the axes (10) of the modular elements constituting the rollers can be carried out by any known mechanical means while retaining the same concept of construction. For example, illustrated in FIG. 11 is a possible mounting implementation. Two pairs of rings (18-19) are used, for example, which are mounted alternately on the connecting pins or pins (10). These rings (18-19) are arranged and shouldered to receive at least one crown (17) of material. flexible and at least one pulley (13) for driving the cables.
Dans la mise en oeuvre illustrée non limitativement figure 11, la première bague (18) présente plusieurs parties étagées (18, 1-18.2-18.3- 18.4) recevant respectivement une première couronne (17), une poulie (13), une seconde couronne (17) puis5présentant une portée d'espacement et d'appui de la seconde bague (19). Cette dernière est agencée et profilée avec des parties étagées (19,1-19.2-19.3) pour autoriser le positionnement successif d'une première poulie (13), d'une couronne (17) et d'une seconde poulie (13), Chaque galet (4-5) est ainsi constitué avec le montage successif et alterné de bagues (18-19) dont le nombre est fonction de la largeur du ruban entrainé. Les poulies sont montées libres en rotation, tandis que les disques 12 et couronnes associées (17) sont entrainés selon le sens de rotation des galets (4-5) en fonction de la position du chariot. Chaque axe ou tige de liaison (10) reçoit à son extrémité supérieure une bague entretoise (20) sur laquelle est disposée et fixée une plaque horizontale profilée de liaison (21) assurant le maintien des galets (4,5) et leur fixation, La plaque de liaison (21) reçoit en outre dans un plan arrière deux tiges (22-23) disposées verticalement pour permettre le passage et guidage de la bande ou ruban en vue de son introduction entre les galets (4- 5). In the implementation illustrated without limitation in Figure 11, the first ring (18) has several stepped parts (18, 1-18.2-18.3- 18.4) respectively receiving a first ring (17), a pulley (13), a second ring (17) then5 having a spacing and support surface for the second ring (19). The latter is arranged and profiled with stepped parts (19,1-19.2-19.3) to allow the successive positioning of a first pulley (13), a crown (17) and a second pulley (13), Each roller (4- 5) is thus constituted with the successive and alternating mounting of rings (18-19), the number of which depends on the width of the entrained ribbon. The pulleys are mounted free to rotate, while the discs 12 and associated crowns (17) are driven in the direction of rotation of the rollers (4-5) depending on the position of the carriage. Each connecting pin or rod (10) receives at its upper end a spacer ring (20) on which is disposed and fixed a horizontal profiled connecting plate (21) ensuring the maintenance of the rollers (4,5) and their fixing, The connecting plate (21) further receives in a rear plane two rods (22-23) arranged vertically to allow the passage and guidance of the strip or ribbon for its introduction between the rollers (4-5).
En étroite relation avec le montage des galets précités, on obtient une multiplication des brins de câbles constituant et définissant ensemble la courroie (15) de poussée de la bande ou ruban. Les différents câbles sont enroulés sur les poulies dans des plans étages successifs en étant parallèles et horizontaux. On obtient ainsi dans l'exemple illustré non limitativement 5 brins (14.1-14.2-14.3-14,4-14.5), Ces brins sont fixés â leurs extrémités â une attache (24) (25) à des hauteurs successives pour conserver leur parallélisme et horizontalité. A cet effet les attaches (24-25) sont disposées du côté de sortie de la bande ou ruban coté mise en plis et conditionnement, en étant décalés angulairement vers l'avant par rapport au plan de la génératrice externe des deux galets (4-5). Les deux attaches (24-25) comprennent une base (24.1-25.1) de fixation sur l'entablement, éventuellement réglable en position pour adapter le degré d'angulation des parties de courroies en fonction des besoins. Chaque base (24,1- 25.1) se prolonge verticalement par un bloc parai lél ipipédique (24,2-25.2) ou d'autres formes agencé notamment avec une pluralité de conduits (24.3.-25.3) autorisant l'engagement des câbles. Des moyens (26) sont associés à chaque conduit pour saisir, maintenir et serrer en position chaque câble en leur conférant une tenue parfaite en position. Chaque bloc peut être agencé avec un nombre important de conduits pour correspondre au nombre de brins de câbles définissant la ou les courroies de poussée en fonction de la largeur du ruban ou bande traité, In close relation with the mounting of the aforementioned rollers, a multiplication of the strands of cables is obtained which together constitute and define the belt (15) for pushing the strip or ribbon. The different cables are wound on the pulleys in successive stages planes being parallel and horizontal. There are thus obtained in the example illustrated without limitation 5 strands (14.1-14.2-14.3-14,4-14.5), These strands are fixed at their ends to a fastener (24) (25) at successive heights to maintain their parallelism and horizontality. To this end, the fasteners (24-25) are arranged on the outlet side of the strip or ribbon on the side of the styling and packaging, being angularly offset forwards relative to the plane of the external generator of the two rollers (4- 5). The two fasteners (24-25) include a base (24.1-25.1) for fixing to the entablature, possibly adjustable in position to adapt the degree of angulation of the parts of the belts as required. Each base (24.1-25.1) is extended vertically by a parallel ipipedic block (24.2-25.2) or other forms arranged in particular with a plurality of conduits (24.3.-25.3) authorizing the engagement of the cables. Means (26) are associated with each conduit for grasping, holding and clamping in position each cable, giving them perfect hold in position. Each block can be arranged with a large number of conduits to correspond to the number of strands of cables defining the pushing belt or belts as a function of the width of the treated ribbon or strip,
Lesdits brins de câbles peuvent définir dans leur continuité une seule et même courroie ou alors deux courroies identiques telles qu'illustrées aux dessins,  Said cable strands can define in their continuity a single belt or else two identical belts as illustrated in the drawings,
Dans la première réalisation possible non illustrée, les différents brins de câbles qui sont guidés par les galets (4,5) sont orientés et contournent des barres de renvoi disposées dans la partie arrière de l'entablement de la manière décrite dans le brevet n° 88,12709.  In the first possible embodiment not illustrated, the different strands of cables which are guided by the rollers (4,5) are oriented and bypass the return bars arranged in the rear part of the entablature as described in patent n ° 88.12709.
Dans la réalisation illustrée aux dessins, les brins de câbles définissent deux courroies identiques et montées en opposition, lesdites courroies étant fixées à l'une de leurs extrémités aux attaches (24- 25) précitées et à l'autre extrémité respectivement â un tambour d'enroulement d'enroulement (27) (35) fixés dans la partie arrière de l'entablement après avoir été renvoyées par les galets (4, 5). Chaque tambour est monté avec une capacité de rotation dans les deux sens en fonction du sens de déplacement du chariot. Les tambours présentent- un aspect lisse sur leur périphérie ou éventuellement cannelé, rainure ou autres pour le guidage des brins de cables. En outre, chaque tambour est agencé avec une zone d'attache et de fixation (27.1) des secondes extrémités des câbles, In the embodiment illustrated in the drawings, the cable strands define two identical belts and mounted in opposition, said belts being fixed at one of their ends to the aforementioned fasteners (24-25) and at the other end respectively to a drum d 'winding winding (27) (35) fixed in the rear part of the entablature after being returned by the rollers (4, 5). Each drum is mounted with a capacity of rotation in both directions depending on the direction of movement of the carriage. The drums have a smooth appearance on their periphery or possibly grooved, groove or the like for guiding the cable strands. In addition, each drum is arranged with an attachment and fixing zone (27.1) for the second ends of the cables,
On a représenté aux figures 9 et 10 le fonctionnement du dispositif, dans le cas de l'utilisation de deux courroies (15) avec une alternance de situation. On procède simultanément à l'enroulement de l'une des courroies et audéroulement de l'autre courroie sur leur tambour respectif, selon la position du chariot.  Figures 9 and 10 show the operation of the device, in the case of the use of two belts (15) with an alternating situation. One proceeds simultaneously to the winding of one of the belts and to the unwinding of the other belt on their respective drum, according to the position of the carriage.
Ainsi selon ce premier aménagement de l'invention, on peut donc obtenir une adaptation du dispositif à la largeur du ruban travaillé d'une partet d'autre part un effet de poussée réglable des parties de ruban ou bandés pliêes.  Thus according to this first arrangement of the invention, it is therefore possible to obtain an adaptation of the device to the width of the worked ribbon on the one hand and on the other hand an adjustable pushing effect on the parts of ribbon or folded bandages.
Cette première caractéristique permet en outre de conférer au dispositif selon l'invention d'autres avantages par l'utilisation d'un moyen complémentairede conception simple mais répondant au problème posé pour certains types de bandés ou rubans ayant une certaine "nervosité", c'est-à-dire ayant tendance à se détendre et ne pas rester dans la forme pliée souhaitée.  This first characteristic also makes it possible to confer on the device according to the invention other advantages by the use of a complementary means of simple design but responding to the problem posed for certain types of bandages or ribbons having a certain "nervousness", it that is, tending to relax and not stay in the desired folded shape.
Pour ce faire, il est utilisé un moyen complémentaire (28) qui est fixé sur la partie avant de l'entablement devant les galets et avantageusement dans le prolongement des blocs d'attache (24-25).  To do this, a complementary means (28) is used which is fixed on the front part of the entablature in front of the rollers and advantageously in the extension of the attachment blocks (24-25).
Plus spécifiquement, ce moyen (28) est réalisé sous la forme d'une barre de grande longueur en étant disposée entre les blocs d'attache précités. Cette barre de section carrée par exemple est montée en surélévation par rapport â l'entablement. Par exemple, la barre est engagée par chacune de ses extrémités surune tige filetée (29) ou moyens similaires fixés dans une ouverture (30) aménagée â cet effet dans l'entablement. Ladite barre est en appui sur une rondelle (30) à l'encontre d'un moyen élastique de rappel (31) tel qu'un ressort à boudin monté sur chaque tige. Des moyens de blocage et- serrage (32) du type contre écrou viennent s'ajuster en position sur chaque tige, en ayant une capacité de réglage de la hauteur de surélévation de la barre par rapport à l'entablement. La barre est ajustée à l'horizontal. La hauteur de surélévation est établie en fonction de la largeur du ruban ou bande plié pour permettre à la sortie des galets (4, 5) l'introduction de la partie du ruban mis en plis sous la barre et son évacuation vers la zone d'évacuation, Ainsi lorsque le chariot est déplacé latéralement selon la course maximum préétablie en fonction de la longueur des plis, les brins de cables de la partie de courroie déroulée viennent en appui et contact dans le même plan de la barre précitée ou les brins de cables inférieurs peuvent être partiellement engagés sous la barre. More specifically, this means (28) is produced in the form of a very long bar by being disposed between the aforementioned attachment blocks. This square section bar for example is mounted in elevation relative to the entablature. For example, the bar is engaged by each of its ends on a threaded rod (29) or similar means fixed in an opening (30) arranged for this purpose in the entablature. Said bar is supported on a washer (30) against an elastic return means (31) such as a coil spring mounted on each rod. Locking and clamping means (32) of the lock nut type are adjusted in position on each rod, having a capacity for adjusting the height of the bar elevation relative to the entablature. The bar is adjusted to the horizontal. The height of elevation is established as a function of the width of the ribbon or band folded to allow the exit of the rollers (4, 5) the introduction of the part of the ribbon folded under the bar and its evacuation to the area of evacuation, So when the carriage is moved laterally according to the maximum preset stroke as a function of the length of the folds, the cable strands of the unwound belt part come into contact and contact in the same plane of the aforementioned bar or the cable strands lower can be partially engaged under the bar.
Selon une originalité intéressante qui peut être utilisée pour certains types de rubans ou bandes, la barre est agencée pour recevoir un doigt (33-34) vertical disposé intérieurement et près de la zone de fixation de celle-ci. Le doigt établi sous forme de tige traverse la barre et constitue par sa partie inférieure un moyen de renvoi intérieur des brins de câbles. Ces derniers pénètrent alors plus prof ondémment sous la barre lors du mouvement correspondant du chariot provoquant ainsi par poussée l'introduction des parties de rubans ou bandes pliées, Ces dernières sont alors maintenues par la pression d'appui de la barre et poussées par les brins de câbles, Ainsi lorsque le chariot se déplace en sens inverse les parties de courroies situées sous la barre se retirent et le ruban est toujours maintenu. Dans le cycle suivant, lorsque la nouvelle partie de ruban sera introduite sous la barre, elle provoquera la poussée de la précédente qui ne pourra plus alors se détendre selon le phénomène qui était rencontré précédemment, La position du doigt (33-34) sur la barre peut être adaptée en fonction des dimensions des longueurs de rubans ou bandes plies. According to an interesting originality which can be used for certain types of ribbons or bands, the bar is arranged to receive a vertical finger (33-34) disposed internally and near the attachment zone thereof. The finger established in the form of a rod crosses the bar and constitutes, by its lower part, an internal return means for the strands of cables. The latter then penetrate more deeply underneath the bar during the corresponding movement of the carriage thus causing, by pushing, the introduction of the parts of folded ribbons or bands, The latter are then maintained by the pressure of support of the bar and pushed by the strands cables, so when the carriage moves in the opposite direction the parts of belts located under the bar are removed and the ribbon is still held. In the following cycle, when the new part of ribbon is introduced under the bar, it will cause the thrust of the previous one which will then no longer be able to relax according to the phenomenon which was encountered previously, The position of the finger (33-34) on the bar can be adapted according to the dimensions of the lengths of ribbons or folded strips.
Les avantages ressortent bien de l'invention. On souligne la simplicité du dispositif, sa facilité de montage, son aspect modulable en fonction des caractéristiques des rubans ou bandes traités. En outre sa mise en oeuvre est simple, son montage rapide et on souligne sa parfaite adaptation à tous types de rubans, et bandes.  The advantages emerge clearly from the invention. The simplicity of the device is emphasized, its ease of assembly, its modular appearance depending on the characteristics of the ribbons or bands treated. In addition, its implementation is simple, its rapid assembly and it underlines its perfect adaptation to all types of ribbons and bands.
