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.
Lorsqu'on utilise des fils d'un seul filament, le tuyau de protection obtenu avec cette machine présente plusieurs inconvénients:When using threads of a single filament, the protective hose obtained with this machine several disadvantages:
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.
Un traitement de chauffage de tels tuyaux est connu des documents suivants.A heating treatment of such pipes is known from the following documents.
Le document WO-A-91/14034 concerne un tuyau tricotressé et son procédé de fabrication. En particulier il décrit un tuyau tricotressé fabriqué de monofilaments en matière plastique élastique. Les extrémités de ces tuyaux ont tendence à s'ouvrir ce qui est résolu en formant une couche d'un matériau solide adhérent sur les filaments du tuyau réduisant la tendance à s'ouvrir mais permettant la rotation des monofilaments entre eux de façon à maintenir la caractéristique d'expansion du tuyau. Le tuyau est introduit dans un bain et après il est chauffé préférablement à 150°C.WO-A-91/14034 relates to a pipe knitted fabric and its manufacturing process. In particular he describes a knitted hose made of monofilaments in elastic plastic material. The ends of these pipes tend to open which is resolved by forming a layer of a solid material adhering to the filaments of the hose reducing the tendency to open but allowing the rotation of the monofilaments between them so as to maintain the expansion characteristic of the pipe. The hose is introduced into a bath and afterwards it is heated preferably at 150 ° C.
Le document EP-A-0134864 concerne aussi un tuyau tricotressé et son procédé de fabrication. Dans ce cas-ci, le problème à résoudre était la difficulté qui se présente au moment de placer le tuyau autour des câbles ou analogues. Ce document prévoit aussi un traitement de chauffage de tuyaux formés par des fils à filaments multiples. Le document EP-A-327 085 décrit également un traitement de chauffage de tels tuyaux.EP-A-0134864 also relates to a pipe knitted fabric and its manufacturing process. In this case, the problem to be solved was the difficulty that arises when placing the hose around the cables or analogues. This document also provides pipe heating treatment formed by multiple filament yarns. The document EP-A-327 085 also describes a treatment for heating such pipes.
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, lesdits tuyaux étant formés par des fils d'un seul filament d'un matériel plastique tricotressés, et étant chauffés à une température comprise entre 130°C et 600°C pendant une période de temps comprise entre 10 secondes et 45 minutes, est tel que pendant l'étape de chauffage, les tuyaux de protection sont également soumis à une tension longitudinale comprise entre 0,1 kg. et. 5 kg pendant une période de temps comprise entre 10 secondes et 45 minutes.The process for the treatment of protection, said pipes being formed by wires of a single filament of knitted plastic material, and being heated to a temperature between 130 ° C and 600 ° C for a period of time between 10 seconds and 45 minutes, is such that during the heating stage, the protective pipes are also subjected to a longitudinal tension included between 0.1 kg. and. 5 kg for a period of time between 10 seconds and 45 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.
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.

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.
