Title (EN) REINFORCED FLEXIBLE HOSE, PROCESS FOR MAKING SAME AS WELL AS PRODUCTION LINE FOR MANUFACTURING THEREOF
(FR) TUYAU SOUPLE RENFORCÉ, PROCÉDÉ DE FABRICATION D’UN TEL TUYAU SOUPLE RENFORCÉ AINSI QU’UNE CHAÎNE DE PRODUCTION DESTINÉE À SA FABRICATION
Abstract:
(EN) A flexible hose reinforced with at least two superimposed textile layers. The hose (1) comprises at least one inner load-bearing tubular layer (2) defining a longitudinal axis (X) made of a first polymeric or elastomeric material, at least one outer cover layer (3) made of a second polymeric or elastomeric material and at least one first (4) and one second (5) reinforced textile layer mutually superimposed and interposed between the inner (2) and outer (3) layer. The first and the second textile layer (4, 5) are both knitted textile layers with chain stitches (6, 6') of the tricot type having courses of stitches (8, 8') and rows of stitches (7, 7'). Both the first textile layer (4) and the second textile layer (5) both have courses of stitches (8, 8') substantially parallel to each other and to the axis (X) and rows of stitches (7, 7') having an opposite inclination (α, β) with respect to the axis (X). A line and a method for manufacturing such hose (1).
(FR) L'invention concerne un tuyau souple renforcé par au moins deux couches textiles superposées. Le tuyau (1) comprend au moins une couche tubulaire porteuse de charge interne (2) définissant un axe longitudinal (X) constitué d'un premier matériau polymère ou élastomère, au moins une couche de revêtement externe (3) constituée d'un second matériau polymère ou élastomère et au moins une première couche textile renforcée (4) et une seconde couche textile renforcée (5), mutuellement superposées et interposées entre la couche interne (2) et la couche externe (3). Les première et seconde couches textiles (4, 5) sont toutes deux des couches textiles tricotées présentant des mailles de chaîne (6, 6') du type tricot ayant des rangées de mailles (8, 8') et des rangs de mailles (7, 7'). La première couche textile (4) et la seconde couche textile (5) présentent toutes deux des rangées de mailles (8, 8') sensiblement parallèles entre elles et à l'axe (X) et des rangs de mailles (7 7') présentant une inclinaison opposée (α, β) à l'axe (X). L'invention concerne également une chaîne et un procédé de fabrication d'un tel tuyau (1).
