Description

       

  
 



   Procédé de fabrication d'un tuyau étanche, et dispositif pour la mise en   oeuvre    de ce procédé
 La présente invention comprend un procédé de fabrication d'un tuyau étanche,   notamment    d'incendie, un dispositif pour la mise en oeuvre de ce procédé, ainsi qu'un tuyau étanche obtenu par ce procédé.



   Les tuyaux étanches employés pour la lutte contre l'incendie, par exemple, sont généralement fabriqués en partant d'une gaine textile tissée qui assure la résistance mécanique du tuyau. L'étanchéité est réalisée par différents moyens, notamment par introduction et collage dans la gaine textile, soit d'un tube non poreux constitué par une armature textile imprégnée de latex ou de matière plastique, soit d'un tube en caoutchouc ou en matière plastique, ou encore par enduction de la gaine textile par du latex ou une matière plastique.



   Ces différents procédés nécessitent en général un outillage compliqué, coûteux et de nombreuses manipulations au cours de la fabrication.



   Les tuyaux obtenus en partant du tissage se tordent ou s'allongent plus ou moins suivant les procédés employés.



   Quand les matières constituant la paroi interne étanche et la gaine textile n'ont pas le mme coefficient d'élasticité, il arrive que sous forte pression la paroi interne se décolle.



   La gaine textile doit tre   manceuvrée    avec précaution, car si un fil de chaîne est détérioré, il y a risque d'éclatement.



   Le procédé que comprend l'invention vise à remédier à   oes    inconvénients.



   Ce procédé est caractérisé en ce que   l'on    constitue son armature au moyen de fils que l'on dispose parallèlement dans le sens de la longueur du tuyau, formant en quelque sorte les génératrices d'un cylindre, et au moyen de fils que l'on dispose transversalement autour dudit cylindre, et en ce qu'on lie les fils intimement entre eux au moyen d'une matière destinée à assurer l'étanchéité du tuyau.



   Le dessin annexé représente, à titre d'exemple, schématiquement et en coupe longitudinale axiale, une forme d'exécution du dispositif que comprend aussi l'invention, pour la mise en oeuvre dudit procédé.



   Des fils a provenant de bobines b disposées tout autour de l'axe x   x' du      dispositif    sont uniformément répartis, au moyen   d'un    peigne annulaire c, suivant les rayons d'un cercle dont le centre se trouve sur l'axe x x'. Ces fils qui, ainsi qu'on le verra plus loin,    sont tirés de e façon continue, passent ensuite sur un guide d en n forme de bague entourant un cylindre    métallique e solidaire d'un plateau e1 fixé à un bâti du dispositif. Le cylindre a un diamètre extérieur un peu inférieur au diamètre intérieur du tuyau à fabriquer.

   Les   liils    sont tirés   parallèlemlent    aux génératrices du cylindre dont ils couvrent toute la surface; ces fils longitudinaux passent dans un bac f contenant par exemple une émulsion de caoutchouc synthétique.



  A la sortie du bac, une raole   t3    règle l'épaisseur de la couche déposée sur les fils.



   Le faisceau de fils enduits passe ensuite dans une zone de chauffage constituée par une enceinte g, chauffée au moyen de résistance   g.    De cette zone de   chauffage,    le faisceau de fils passe dans une zone de refroidissement constituée par une enceinte g2, adjacente à - l'enceinte g, dans laquelle est amené de l'air frais, au moyen d'une canalisation g3.  



   L'opération d'enduction suivie d'un chauffage et d'une ventilation peut tre répétée plusieurs fois le long du cylindre e pour obtenir une pellicule étanche d'épaisseur désirée.



   Le tube h ainsi formé, qui doit constituer la paroi interne étanche du tuyau, arrive en haut du cylindre e dont le bord supérieur e2 est renflé et arrondi.   I1    se replie autour de ce bord et pénètre à l'intérieur du cylindre pour s'enfiler sur un mandrin i coaxial au cylindre e. Ce mandrin est maintenu par une tige il fixée au bâti n2 du dispositif.



   Pour faciliter le glissement du tube h sur le mandrin i on introduit du talc ou un autre lubrifiant par la partie supérieure ouverte du cylindre e.



   Autour du   mandrin    i et concentrique à lui, tourne un plateau j lequel est entraîné en rotation, au moyen d'un engrenage   i2,    en prise avec un pignon   j3    porté par l'arbre j4 d'un moteur   15.   



   Le plateau j porte des bobines   li    sur lesquelles sont enroulés des fils k. Ce plateau, qui forme plateau navette, en tournant autour du tube h dépose sur lui des fils transversaux. Le rapport entre la vitesse de rotation du plateau et la vitesse de déplacement linéaire du tube h donne ce qu'on appellera, par assimilation, le duitage.



   Les fils transversaux, entraînés par un système de rouleaux   kl,    k2,   k3,    sont enduits par passage dans un bac i2, contenant par exemple une émulsion de caoutchouc synthétique.



   Dans certains cas, il peut y avoir intért à régler la tension des fils transversaux k. Pour régler cette tension, on peut commander les rouleaux k3 sur lesquels passent les fils de manière à exercer une traction plus ou moins grande sur les fils. Cette commande est liée à la rotation du plateau.



   Le tube passe ensuite dans une zone de chauffage   1    assuré par des résistances 12, puis dans une zone d'air frais ventilé   li,    amené par une canalisation 13.



   L'opération suivante consiste à faire passer une nouvelle nappe de fils   longitudinaux    m analogue à la nappe de fils   4      dans un    bain d'enduction   m±    (émulsion de latex par exemple) et à amener ces fils au moyen d'une bague n contre le tuyau h en fabrication.

   Après passage sous une racle   nl,    un second plateau navette o, entraîné en rotation par des moyens analogues à ceux décrits pour le plateau navette j, dispose autour de ces fils longitudinaux des fils transversaux p enduits par passage au moyen de rouleaux
P1, P2,   P3    dans un bac   01.    L'ensemble passe ensuite dans une zone de chauffage q assuré par des résistances q2, puis dans une zone d'air frais ventilé q1, amené par une canalisation   q3.   



   On peut donner, au plateau navette o, un sens de rotation inverse par rapport au sens de rotation du plateau navette j, par exemple,   comme    représenté, en inversant, dans le cas du plateau o, l'attaque de l'engrenage    1,    par le pignon    2    porté par l'arbre o3 du moteur 04.



   Suivant l'épaisseur du tuyau à obtenir et les qualités désirées (résistance, souplesse, etc.) les opérations qui précèdent peuvent tre répétées plusieurs fois.



   Le tuyau terminé passe entre des rouleaux d'appel r situés à l'extrémité s du mandrin qui est conformée, comme le montre le dessin, pour faciliter le glissement du tuyau fini.



   Dans le cas où l'on veut éviter l'écrasement du tuyau, les rouleaux d'appel peuvent tre remplacés par un dispositif d'entraînement à glissières ou autre, entre lesquelles le tuyau se trouve saisi et tiré.



   Dans le procédé décrit, les fils longitudinaux étant enduits en   cours    de fabrication du tuyau et étant travaillés et fixés sous tension, l'allongement que peut prendre le tuyau est presque nul.



     I1    est possible, en outre, d'employer pour les fils longitudinaux ou pour   une    partie de ceux-ci, des fils métalliques, en acier inoxydable par exemple, ou des crins synthétiques présentant une grande résistance à la traction.



   La torsion que tend à prendre le tuyau peut tre réduite ou presque annulée par l'emploi de fils ayant des torsions de sens différents.



   Le tuyau pouvant tre constitué de plusieurs couches de fils longitudinaux et transversaux, sa résistance à l'abrasion est   considérablement    augmentée. Si   nu    fil extrme est coupé accidentellement, la résistance du tuyau   reste    acceptable.



   La répartition uniforme des fils longitudinaux et transversaux augmente la résistance et permet, pour un mme résultat, de réduire le poids de matière employée.



   Outre les avantages de qualité du produit fini, le procédé décrit permet la fabrication à un prix de revient raisonnable de presque tous les genres de tuyaux, souples, semi-rigides ou rigides.



   Le dispositif représenté est vertical.   I1    est bien entendu que la fabrication peut tre également réalisée horizontalement d'après le mme principe.
  



  
 



   Method of manufacturing a sealed pipe, and device for implementing this method
 The present invention comprises a method of manufacturing a sealed pipe, in particular a fire hose, a device for implementing this method, as well as a sealed pipe obtained by this method.



   Watertight hoses used in fire fighting, for example, are generally made from a woven textile sheath which provides the mechanical strength of the hose. Sealing is achieved by various means, in particular by introduction and gluing in the textile sheath, either of a non-porous tube consisting of a textile reinforcement impregnated with latex or plastic, or a rubber or plastic tube. , or by coating the textile sheath with latex or a plastic material.



   These different processes generally require complicated, expensive tooling and numerous manipulations during manufacture.



   The pipes obtained by starting from the weaving twist or stretch more or less depending on the processes used.



   When the materials constituting the sealed internal wall and the textile sheath do not have the same coefficient of elasticity, the internal wall may become detached under high pressure.



   The textile sheath must be handled with care, because if a warp thread is damaged, there is a risk of it bursting.



   The method which the invention comprises aims to remedy these drawbacks.



   This process is characterized in that its reinforcement is formed by means of wires which are arranged in parallel in the direction of the length of the pipe, forming in a way the generatrices of a cylinder, and by means of wires that the 'is arranged transversely around said cylinder, and in that the son is bonded intimately together by means of a material intended to seal the pipe.



   The appended drawing represents, by way of example, schematically and in axial longitudinal section, an embodiment of the device which the invention also comprises, for the implementation of said method.



   Yarns a coming from coils b arranged all around the axis xx 'of the device are uniformly distributed, by means of an annular comb c, along the radii of a circle whose center is on the axis x x' . These threads which, as will be seen below, are drawn continuously, then pass over a guide d in the form of a ring surrounding a metal cylinder e secured to a plate e1 fixed to a frame of the device. The cylinder has an outside diameter that is slightly smaller than the inside diameter of the pipe to be manufactured.

   The wires are drawn parallel to the generatrices of the cylinder, of which they cover the entire surface; these longitudinal threads pass through a tank f containing, for example, a synthetic rubber emulsion.



  On leaving the tank, a role t3 adjusts the thickness of the layer deposited on the wires.



   The bundle of coated wires then passes through a heating zone formed by an enclosure g, heated by means of resistance g. From this heating zone, the bundle of wires passes into a cooling zone formed by an enclosure g2, adjacent to the enclosure g, into which fresh air is supplied, by means of a pipe g3.



   The coating operation followed by heating and ventilation can be repeated several times along the cylinder e to obtain a waterproof film of the desired thickness.



   The tube h thus formed, which must constitute the sealed internal wall of the pipe, arrives at the top of the cylinder e, the upper edge e2 of which is swelled and rounded. I1 folds around this edge and penetrates inside the cylinder to slip onto a mandrel i coaxial with cylinder e. This mandrel is held by a rod it fixed to the frame n2 of the device.



   To facilitate the sliding of the tube h on the mandrel i, talc or another lubricant is introduced through the open upper part of the cylinder e.



   Around the mandrel i and concentric with it, turns a plate j which is driven in rotation, by means of a gear i2, in engagement with a pinion j3 carried by the shaft j4 of a motor 15.



   The plate j carries reels li on which are wound k son. This plate, which forms a shuttle plate, rotating around the tube h deposits on it transverse threads. The ratio between the speed of rotation of the plate and the speed of linear displacement of the tube h gives what will be called, by assimilation, dueding.



   The transverse threads, driven by a system of rollers kl, k2, k3, are coated by passing through a tank i2, containing for example a synthetic rubber emulsion.



   In some cases, it may be advantageous to adjust the tension of the transverse yarns k. To adjust this tension, the rollers k3 can be controlled over which the son pass so as to exert a greater or lesser traction on the son. This command is linked to the rotation of the plate.



   The tube then passes through a heating zone 1 provided by resistors 12, then into a zone of ventilated fresh air li, supplied by a pipe 13.



   The following operation consists in passing a new layer of longitudinal threads m similar to the layer of threads 4 in a coating bath m ± (latex emulsion for example) and in bringing these threads by means of a ring n against the h pipe in production.

   After passing under a doctor blade nl, a second shuttle plate o, driven in rotation by means similar to those described for the shuttle plate j, has around these longitudinal wires transverse wires p coated by passing them by means of rollers
P1, P2, P3 in a tank 01. The assembly then passes into a heating zone q provided by resistors q2, then into a zone of ventilated fresh air q1, supplied by a pipe q3.



   The shuttle plate o can be given a reverse direction of rotation with respect to the direction of rotation of the shuttle plate j, for example, as shown, by reversing, in the case of the plate o, the drive of the gear 1, by the pinion 2 carried by the shaft o3 of the motor 04.



   Depending on the thickness of the pipe to be obtained and the qualities desired (strength, flexibility, etc.), the preceding operations can be repeated several times.



   The finished pipe passes between take-off rollers r located at the end s of the mandrel which is shaped, as shown in the drawing, to facilitate sliding of the finished pipe.



   In the case where it is desired to avoid crushing the pipe, the take-up rollers can be replaced by a sliding drive device or the like, between which the pipe is gripped and pulled.



   In the method described, the longitudinal wires being coated during the manufacture of the pipe and being worked and fixed under tension, the elongation which the pipe can take is almost zero.



     It is also possible to use for the longitudinal son or for a part thereof, metal son, stainless steel for example, or synthetic horsehair exhibiting a high tensile strength.



   The twist which the pipe tends to take can be reduced or almost canceled out by the use of wires having twists in different directions.



   Since the pipe can be made up of several layers of longitudinal and transverse wires, its resistance to abrasion is considerably increased. If the end wire is accidentally cut, the resistance of the pipe remains acceptable.



   The uniform distribution of the longitudinal and transverse threads increases the resistance and makes it possible, for the same result, to reduce the weight of material used.



   In addition to the quality advantages of the finished product, the method described allows the manufacture at a reasonable cost of almost all kinds of pipes, flexible, semi-rigid or rigid.



   The device shown is vertical. It is understood that the manufacture can also be carried out horizontally according to the same principle.
