Abstract: A flat flexible hose for transporting a fluid, for example water, is adapted to move between an inoperative position having a flattened configuration and an operative position, in which the hose expands radially under pressure from the fluid. The hose has a first inner layer defining an axis, a second covering layer, and a reinforcement textile layer therebetween. The first and second layers are made of a first and respectively a second thermoplastic elastomeric material adapted to adhere to each other. The reinforcement textile layer is made of rigid textile yarns which at least partially have a respective first and second predetermined inclination opposite to each other so that the length of the hose remains unchanged both in the inoperative and the operative positions. The reinforcement textile layer is a knitted layer with tricot chain stitches with rows of stitches and courses of stitches made of chain stitches.

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: An ultra-lightweight reinforced flexible hose for transporting fluids, in particular a flexible garden hose for transporting water, includes an inner tubular layer made of a first elastomeric or thermoplastic elastomer material; an outer cover layer made of a second elastomeric or thermoplastic elastomer material; and a reinforcement layer interposed between the inner layer and the outer layer. The reinforcement layer is made of a rigid or slightly elastic textile threads having, at least partially, a first and second predetermined inclination that are mutually opposite with respect to a longitudinal axis, each of the first and second inclinations being between 45° and 55° with respect to the longitudinal axis.

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.

Abstract: A flexible hose, as viewed from the inside, includes at least one first inner layer made of a first thermoplastic polymer material, at least one reinforcement layer composed of a plurality of yarns knitted together to form a plurality of stitches of tricot type, and at least one second layer made of a second thermoplastic polymer material. At least one first yarn of the yarns that form the at least one reinforcement layer is a high tenacity fiber and at least one second yarn is a polyester fiber yarn or the like interwoven with the first yarn. A method of making such hose.
