Abstract

Process for treating protective sheaths consisting of braided monofilament synthetic fibers comprises heating the sheath at 130-600 degrees C for 10 seconds to 45 minutes.

Description

La présente invention concerne un procédé pour le traitement de tuyaux de protection mécanique et thermique pour engainer des faisceaux de câbles, des tuyaux métalliques, en caoutchouc, et autres.The present invention relates to a method for treatment of mechanical and thermal protection pipes for sheathing bundles of cables, pipes metallic, rubber, and others.

ANTÉCÉDENTS DE L'INVENTIONBACKGROUND OF THE INVENTION

La technologie du tricotressage est connue depuis longtemps. Cette technologie s'utilise pour la fabrication de tuyaux de protection, aussi bien mécanique que thermique, pour engainer des faisceaux de câbles, des tuyaux et autres.Knitting technology has been known since long time. This technology is used for manufacturing protective pipes, both mechanical and thermal, for sheathing cable harnesses, pipes and others.

La matière première utilisée pour la fabrication de ces tuyaux de protection sont des fils divers, de telle façon que dans chaque aiguille de la machine de tricotressage un nombre déterminé de fils est mis en place.The raw material used to manufacture these protective pipes are various wires, such way that in each needle of the machine knitting a determined number of threads is put in place.

Le tuyau de protection obtenu avec cette machine présente plusieurs inconvénients:The protective hose obtained with this machine has several drawbacks:

Le tuyau a tendance à s'enrouler aux extrémités du tuyau en formant de petites circonférences.The hose tends to curl at the ends of the pipe forming small circumferences.

En sortant de la machine, le tuyau n'a aucune expansibilité du diamètre, c'est-à-dire que le diamètre n'augmente pas, en s'ajustant uniquement à une forme qui ait le diamètre interne du tuyau.When leaving the machine, the hose has no expandability of the diameter, i.e. the diameter does not increase, adjusting only to a shape that have the internal diameter of the pipe.

Le tuyau, en sortant de la machine, a une expansibilité longitudinale, le diamètre de celui-ci pouvant se réduire.The hose, coming out of the machine, has a longitudinal expandability, the diameter of it can be reduced.

Si l'on coupe le tuyau longitudinalement, le tuyau s'enroule de façon perpendiculaire à la coupe.If you cut the pipe longitudinally, the pipe wraps perpendicular to the cut.

Actuellement, on ne connaít aucun tuyau de protection formé par des fils d'un seul filament d'un matériel plastique, étant donné qu'ils ont peu d'utilité dû aux inconvénients cités antérieurement.Currently, there is no known pipe protection formed by threads of a single filament of a plastic material, since they have little use due to the disadvantages mentioned above.

DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION

Avec le procédé de l'invention on réussit à résoudre les inconvénients cités, tout en présentant d'autres avantages qui seront décrits.With the process of the invention we succeed in resolve the disadvantages mentioned, while presenting other advantages which will be described.

Le procédé pour le traitement de tuyaux de protection se caractérise en ce que le tuyau est chauffé à une température comprise entre 130°C y 600°C, préférablement entre 150°C y 400°C et pendant une période de temps comprise entre 10 secondes et 45 minutes, préférablement entre 0,5 et 30 minutes.The process for the treatment of protection is characterized in that the hose is heated to a temperature between 130 ° C and 600 ° C, preferably between 150 ° C and 400 ° C and for a period of time between 10 seconds and 45 minutes, preferably between 0.5 and 30 minutes.

Les températures et le temps dépenderont du matériel du tube à traiter, lequel sera chauffé jusqu'à une température comprise entre 130°C y 190°C.Temperatures and weather will depend on material of the tube to be treated, which will be heated to a temperature between 130 ° C and 190 ° C.

De façon avantageuse, pendant l'étape de chauffage, le tuyau de protection se soumet également à une tension longitudinale comprise entre 0,1 kg et 5 kg pendant une période de temps comprise entre 0,5 et 30 minutes.Advantageously, during the heating step, the protective hose is also subjected to tension between 0.1 kg and 5 kg during a time period between 0.5 and 30 minutes.

Avec le traitement thermique appliqué au tuyau on obtient l'élimination des inconvénients cités antérieurement. En outre, en appliquant de la tension au moment du traitement thermique, on obtient l'ajustement du diamètre intérieur du tuyau à un diamètre souhaité. De cette façon, après le traitement on obtient un tuyau qui s'ajuste à une gamme de diamètres comprise entre le diamètre d'origine du tuyau et le diamètre qui s'obtient après le traitement.With the heat treatment applied to the pipe we obtains the elimination of the disadvantages mentioned previously. In addition, by applying tension to the at the time of the heat treatment, the adjustment of the inner diameter of the pipe to a desired diameter. Of this way, after the treatment we get a pipe which adjusts to a range of diameters from original diameter of the pipe and the diameter obtained after treatment.

Selon une réalisation de l'invention, des fils à filaments multiples sont incorporés au dit tuyau avant le chauffage du tuyau de protection. According to one embodiment of the invention, wires to multiple filaments are incorporated into said pipe before the protection hose heating.

De préférence, on incorpore au dit tuyau des fils d'un matériel texturisé avant le chauffage du tuyau de protection.Preferably, wires are incorporated into said pipe textured material before heating the protection.

De façon avantageuse, le tuyau est imprégné de résine avant le chauffage de celui-ci. Cette imprégnation avec de la résine se réalise uniquement lorsque le tuyau comprend des fils d'un matériel texturisé, qui ont une grande absorption, ou bien des fils à filaments multiples, qui ont également de l'absorption, bien que moins importante que celle des fils d'un matériel texturisé. Cette imprégnation renforce encore plus la stabilité dimensionnelle et un degré de dureté et de flexibilité plus élevé peut être donné. En outre, en coupant le tuyau il ne s'effile pas du tout, celui-ci pouvant être monté à la fin d'une installation.Advantageously, the pipe is impregnated with resin before heating it. This impregnation with resin is realized only when the pipe includes yarns of textured material, which have a high absorption, or multiple filament yarns, which also have absorption, although less important than that of the threads of a textured material. This impregnation further strengthens the stability dimensional and a higher degree of hardness and flexibility high can be given. In addition, by cutting the pipe it does not does not taper at all, it can be mounted at the end of an installation.

Selon une réalisation préférée de l'invention, les fils d'un seul filament ont un diamètre compris entre 1,1 mm et 0,3 mm.According to a preferred embodiment of the invention, the single filament yarns have a diameter of between 1.1 mm and 0.3 mm.

De préférence, le tuyau est imprégné avec de la résine de silicone ou acrylique.Preferably, the pipe is impregnated with silicone or acrylic resin.

Selon une réalisation préférée, les fils d'un seul filament sont d'un matériel plastique choisi entre polyester, polyamide et polytétra-fluoréthylène (PTFE), alors que les fils à filaments multiples et les fils d'un matériel texturisé sont en polyester ou en polyamide.According to a preferred embodiment, the son of a single filament are of a plastic material chosen between polyester, polyamide and polytetra-fluorethylene (PTFE), while the filament yarns and the yarns of a textured material are polyester or polyamide.

Si on le souhaite, le tuyau peut se couper longitudinalement après le chauffage de celui-ci. Grâce à l'application du procédé de l'invention, le tuyau ne se déforme pas, celui-ci pouvant être appliqué sur des objets déjà montés.If desired, the pipe can be cut longitudinally after heating it. Thanks to application of the method of the invention, the pipe does not not deform, it can be applied to objects already mounted.
