Abstract: 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.

Abstract: A method for manufacturing a hose/connector assembly of polymeric material includes the steps of: providing a flexible hose of a first thermoplastic material; providing the connector of a second thermoplastic material having a hardness greater than the first thermoplastic material and a first end for coupling with a liquid source and a second end with a seat for receiving one end of the hose; translating the end of the flexible hose to engage the seat of the connector; rotating the connector to cause a rotational friction welding with the flexible hose; and periodically comparing the welding torque with the maximum allowable torque for the hose and the connector. The step of rotating the connector with respect to the hose is interrupted if the welding torque is equal to or greater than the maximum allowable torque.

Abstract: A flexible hose for transporting a fluid, particularly a flexible garden hose for transporting water, includes an outer sheath and an inner tube. The inner tube has an inner layer made of a first elastic polymeric material and an outer layer made of a second elastic polymeric material with a textile reinforcement layer embedded within the inner tube to form a unitary tubular member. The elasticity of the unitary tubular member is such that it automatically elongates under the working pressure provided by a liquid flowing therethrough and automatically recovers its original length when the working pressure stops. The textile reinforcement layer is adapted to move from a rest configuration when there is no working pressure, to a working configuration when the unitary tubular member elongates under the working pressure.

According to a preferred embodiment the lines (5) of said meshes are slanted in relation to the longitudinal axis Y of the hose, following a direction opposite to the direction of the mesh rows (6).
