20140110013 | Flexible hose structure with a interlaced reinforcement - A flexible hose structure includes at least one inner tubular layer of a first polymeric material defining a longitudinal axis, at least one meshed intermediate reinforcement layer arranged on the inner layer and having at least one first series of yarns defining first chained wales and first courses arranged according to a helical progression with a first pitch of predetermined length, and at least one second series of yarns defining second chained wales and second courses arranged according to a helical progression with a second pitch of predetermined length. The first pitch is a multiple of the second pitch, and the first wales (and the second wales are mutually interlaced with respective meshes not in a chain to exert an independent resistance to radial expansion on the inner layer. | 04-24-2014 |

20130118629 | Integral pipe and fitting assembly of polymer material, and method of making same - A hose and fitting assembly includes a hose of a first thermoplastic polymer material having an end portion with an inner surface and an outer surface and a fitting of a second polymer material for connection with an external point of use. The fitting has a central tubular projection with an axial fluid passageway. The central tubular projection has an inner wall which defines the fluid passageway and an outer wall, at least partly integrally coupled to the inner surface of the end portion of the hose. The hose and fitting assembly includes a reinforcement member of a third polymer material at the periphery of the end portion of the hose for restraining radial deformations of the hose and providing the assembly with a good mechanical and/or hydraulic sealing capability. A method of making such assembly. | 05-16-2013 |

20110209791 | Multilayer Flexible Irrigating Hose - A multilayer flexible irrigation hose includes an inner layer made of a first thermoplastic polymer material, an outer layer made of a second thermoplastic polymer material, and a first textile reinforcement layer and a second textile reinforcement layer in mutually overlapping relation. The first and second textile reinforcement layers are knitted with stitches of the tricot type, having wales of stitches and lines of stitches. The lines of stitches of said first and second textile layers have opposite inclinations to the longitudinal axis of the hose, and the wales of stitches of at least one of said first and second textile layers are substantially parallel to said longitudinal axis. A method of making said hose, a line for manufacturing same and a knitting apparatus for making such hose are also disclosed. | 09-01-2011 |
