Definitions
- the conventional processes for manufacturing such reinforced tubes mainly comprise the extrusion of a rubber tubular substrate, the winding, overbraiding or overknitting of a fabric fibre on this substrate, and then the extrusion of a new rubber layer in order to embed the fabric reinforcement.
- the recovery ratios are less than 40%, that is to say the difference in length of a yarn before and after heat recovery remains less than 40% of its initial length.
- the multifilament yarn being more compressible than the monofilament yarn, can absorb, by being compressed, a slight additional recovery of the sleeve caused by the monofilament yarn beyond its intrinsic recoverability.
- the strands are interlaced in the form of a flexible tubular braid, the diameter of the said braid increasing with the longitudinal compression of the said braid.
- the monofilament yarn is made of polyethylene terephthalate having great elasticity and the multifilament yarn is made of a high-tenacity polyamide.
- the interlaced strands 2, 3 form an elastically deformable tubular structure.
- the recovery ratio of the monofilament yarn 2 is between 1 times and 3 times the recovery ratio of the multifilament yarn 3, and preferably between 1.5 times and 2 times the recovery ratio of the multifilament yarn 3.
- the recovery ratio of the monofilament yarn 2 may be between 0.5 times and 4 times the recovery ratio of the multifilament yarn.
- the recovery ratio of the monofilament yarn 2 is between 15% and 25% and the recovery ratio of the mulifilament yarn is between 8% and 15%.
- the proportions of monofilament yarns and of multifilament yams in the fabric sleeve may vary over a wide range since the elasticity of the sleeve remains sufficient to allow easy fitting.
- the interlaced strands comprise between two monofilament yarns 2 per one multifilament yam 3 and one monofilament yarn 2 per ten multifilament yarns 3, and preferably between one monofilament yarn 2 per one multifilament yarn 3 and one monofilament yarn 2 per four multifilament yarns 3.
- the proportion is advantageously one monofilament yarn 2 per three multifilament yarns 3.
- the monofilament yarn 2 used for its elasticity will preferably be made of polyethylene terephthalate.
- It may consist of any polymer having a high modulus of elasticity, such as olefin polymers, polyesters, polyphenylene oxides and sulphides, silicone-carbonate block copolymers, polyketones, polysulphones, polycarbonates, polyamides, epoxy resins and blends of these materials among themselves.
- the multifilament yarn 3 used for its abrasion resistance will preferably consist of a polyamide, such as a nylon-6 or a nylon-6,6. Any other type of polyamide polymer or of abrasion-resistant polymer may be chosen.
- This fabric sleeve 1 is fitted onto a rubber tube according to a manufacturing process illustrated in Figures 3A to 3E.
- a cutting device 6 Downstream of the extruder 5, a cutting device 6 allows the rubber tube 4 to be cut to a predetermined length.
- Figure 3C then illustrates the fitting of the fabric sleeve 1 on the tube 4, the diameter of the sleeve 1 being slightly greater than the diameter of the rubber tube 4.
- the rubber tube 4 fitted onto the mandrel 7 and covered by the fabric sleeve 1, is vulcanised as illustrated in Figure 3D, preferably in an autoclave oven 8.
- This vulcanisation causes heat recovery of the fabric sleeve 1, which thus perfectly matches the external surface of the rubber tube 4.
- the vulcanisation is preferably carried out at a temperature of approximately 180°C.
- the vulcanisation temperature depends, of course, on the type of rubber used for manufacturing the tube 4.
- the mandrel 7 is removed, as illustrated in Figure 3E, after the vulcanisation step.
- the recovery ratios of the strands making up the fabric sleeve 1 are not too high so that the heat-recovery force generated by the fabric sleeve 1 does not impede the operation of removing the mandrel.
