The expansion hose may be part of an assembly including at least one fitting, coupling, bracket, hose clamp, or other hose.

Vehicular tire and process of making the same. The tire includes a carcass made of rubber, sidewalls, and tread. The carcass, in a sidewall region, includes at least one carcass ply having parallel textile reinforcements embedded in the rubber and two carcass ply ends, and the two carcass ply ends are arranged to overlap in a circumferential direction, thereby forming an overlapping point. A sidewall rubber strip is positioned to cover the carcass in the sidewall region, and a moiré pattern is formed on the sidewall rubber strip. The process includes circumferentially overlapping the two carcass ply ends of the carcass, thereby forming an overlapping region, covering the overlapping region on the outside with a sidewall rubber strip, and forming a moiré pattern on the sidewall rubber strip.

The invention relates to gymnastic and exercise equipment and can be used for physical exercises to develop and strengthen body muscles, for carrying out sports events and in leisure activities. Said invention makes it possible to increase the durability of the training device, the elasticity of the surface thereof and to extend the possibilities for modifying the shape of training device as a result of its structure, comprising a pressurized torus-shaped sealed reinforced chamber which is provided with a flush-mounted valve and means for modifying the shape of the chamber. Said reinforced chamber consists of an internal hermetic chamber and multilayer textile reinforcement, located on screw line around hermetic internal chamber, wherein the coils of the textile reinforcement of adjacent layers are oppositely oriented with angle between coils of 30 to 150°, and of an outer sheath made of an elastic cloth.

An air spring assembly for a motor vehicle, including an air spring, a rolling piston, a tubular rolling air spring bellows arranged concentrically about a central longitudinal axis of the air spring, and an air spring cover. A first partial air spring bellows has a first embedded textile reinforcement and a second partial air spring bellows has a second embedded textile reinforcement The first textile reinforcement has first reinforcing threads, the preferred axis of which extends parallel or nearly parallel to the axis of the central longitudinal axis of the air spring The second textile reinforcement has second reinforcing threads, the first preferred axis of which extends obliquely to the longitudinal axis of the air spring and the second preferred axis of which extends obliquely to the longitudinal axis of the air spring, wherein the first and the second preferred axis are at an angle to each other.

A flexible hose (1) has at least two textile reinforcement inlays or inserts (5, 6, 7) and an inner layer (2) made of elastomeric material. The flexible hose can assume various curvature geometries and, on the other hand, is still pressure-resistant because a textile reinforcement inlay (5) made of a peripherally closed, tubular knitted or woven fabric is applied to the elastomeric inner layer (2). A textile layer (6), which is rubber-coated on both sides, is wound as a further textile reinforcement inlay onto the tubular knitted or woven fabric (5).

A hose that includes an inner layer and an outer layer made of an elastic polymeric material, and a textile reinforcement layer interposed between the inner and the outer layers. The inner layer and the outer layer are reciprocally coupled to form a unitary tubular member, within which the textile reinforcement layer is embedded. The unitary tubular member has an elasticity such to automatically elongate under the working pressure given by the liquid flowing therethrough to increase its original length and to automatically recover once the working pressure stops. The textile reinforcement layer is adapted to move from a rest configuration when the working pressure stops to a working configuration when the unitary tubular member elongates under the working pressure, and vice versa.

The invention relates to a hose, comprising an elastomeric material and a textile reinforcement, the textile reinforcement being made substantially of fibers selected from the group of aliphatic polyamides, characterized in that the heat shrinkage of the fibers is smaller than 2.5%.

The invention is directed to a drive belt of rubber or rubber-like plastic having a surface protection (5) which includes polyamide-containing textile reinforcement and/or polyester-containing textile reinforcement. On the outer side, a surface coating (6) of a friction-reducing material in a matrix of at least one elastic addition polymer is provided. For improved heat resistance with good protection against wear, the elastic addition polymer has at least 2% by weight based on the polymer of structural components —O—C_xR_y—O— with x=1-3 and y=0-6. The R in a structural component can be the same or can be different and is selected from hydrogen and/or carbon-containing groups.

A flexible hose for transporting a fluid, particularly a flexible garden hose for transporting water, includes an inner layer made of a first elastic polymeric material; an outer layer made of a second elastic polymeric material; and a textile reinforcement layer interposed therebetween. The inner and outer layers are reciprocally coupled to form a unitary tubular member, internally to which the textile reinforcement layer is embedded. The elasticity of the unitary tubular member causes it to automatically enlarge under the working pressure given by the liquid flowing therethrough to increase its original diameter and to automatically recover to assume again its original diameter once the working pressure stops. The textile reinforcement layer is susceptible to move from a rest configuration, when there is no working pressure, to a working configuration, when the unitary tubular member enlarges upon under the working pressure.

A tire for heavy loads and having beads intended to be mounted on flat rim seats or rim seats which are inclined at 5°, including at least one radial carcass ply formed of inextensible reinforcement elements and anchored in each bead to a bead wire to form an upturn, the end of which is located at a radial distance HRNC from the base of the bead. Each bead is reinforced by at least two additional reinforcement armatures, at least one first armature formed of at least one ply of radial textile reinforcement elements which is located axially to the outside of a second armature formed of at least one ply of inextensible elements forming an angle alpha with the circumferential direction such that 0°<=alpha<=45°.

The invention concerns a composite system for reinforcing, in particular, structures made from reinforced concrete or masonry comprising a curable or cured matrix and a textile reinforcement grid, and said two elements taken as such. The aim of the invention is for this system to make it possible to produce a cured composite structure having improved mechanical properties, both in the short term and in the long term (e.g. flexing behaviour, hardness, bending/compression resistance, durability, cohesion). This aim is achieved by the system of the invention in which the grid comprises at least one layer formed: —both from a framework consisting of flat warp yarns and weft yarns; —and from a network binding the framework; characterised in that the binding network is such that it ensures the geometric regularity and dimensional stability of the meshes of the framework, before the grid is applied to the structure to be reinforced. The invention also concerns a method for reinforcing, in particular, structures made from reinforced concrete or masonry, the composite structure obtained from this method, the dry and wet formulations of the curable matrix, and consolidated structures, in particular made from reinforced concrete or masonry.

The invention relates to a load-bearing structure and to a method for producing a load-bearing structure, in particular of wind turbine towers, which provides for a concrete hollow body having an outer wall which is produced by several wet in wet produced layers (22, 26). The outer layer (26) is a layer of fine grained concrete, provided with a textile reinforcement (28), and the inner layer (22) is made from mass concrete.
