Abstract: The object of the invention is a method for building hoses reinforced with spirally laid fibers, where the hose under construction (3) undergoes both rotation and advancing motion relative to the laying head (12), and where the reinforcing fibers are unwound from drums (14). The drums (14) are rotated about two axes, the first axis being the principal axis of the drums (A) and the second axis (B) being nearly parallel with the direction in which the fibers are unwound, where the direction of rotation of the drums (14) about the second axis (B) is the same as the direction in which the hose under construction (3) is rotated.

Abstract: A long-length hose spliced from two or more hoses containing an inner sealing layer, at least two spirally laid reinforcing plies, and a cover. A liner forming the inner sealing layer is formed by leak-tight splicing of liners of hoses to be spliced and the reinforcing plies are embedded into filling/adhesive material inside of a rigid outer sleeve, at the location of the splicing.

Abstract: A hose coupling for high-pressure hoses includes a stem and a ridged outer ferrule connected to the stem, wherein a staggered portion is disposed on the stem in the proximity of the connection of the stem and the ridged outer ferrule, where the diameter of the staggered portion is larger than the diameter of the stem, and the staggered portion has an undercut and a cutting edge. Also, a high-pressure hose fitted with the above swaged coupling, and a method for producing it. In the method, prior to swaging, the cover of the hose is removed at the portion where the cover is in connection with the ridges of the ridged outer ferrule of the hose coupling, and the hose liner and an optionally included load distribution textile ply or cord fabric ply are also removed from the hose end before swaging at a length not longer than the length of the staggered portion of the stem.

Abstract: The invention relates to a hose that comprises at least one inner layer (1) produced from an elastomer material, an embedded reinforcement carcass produced from a textile and/or metal material, an outer layer produced from an elastomer material and a coupling having a flange section inside the hose end. The inventive hose is characterized in that the coupling comprises a fitting, a supporting flange and at least one annular lamina. A first reinforcement carcass, consisting of at least one reinforcement layer, extends along the entire inside of the fitting and changes in the flange area from the axial to the radial direction of extension. The radial area of the first reinforcement carcass is mounted between the supporting flange and the annular lamina(e). A second reinforcement carcass, likewise consisting of at least one reinforcement layer, partially or completely holds the outside of the fitting, especially by way of fastening means.

Abstract: The object of the invention is a high-pressure rubber hose comprising a liner (1), rubberized textile layers (2), main reinforcing plies (3) and a cover (5). The invention is essentially characterised by that the hose has an integrated coupling (7) and a permanent two- or three-dimensionally curved shape, which shape it retains in the absence of external force. The method according to the invention comprises the steps of building the high-pressure hose from its structural elements on a mandrel, providing an integrated coupling (7) to the hose, securing the coupling to the hose, removing the built-up hose structure from the mandrel, producing the desired final shape of the hose before vulcanization, and retaining the final shape by keeping the hose fixed during vulcanization. The apparatus according to the invention is essentially characterised by that it comprises blinds (12) matching the hose couplings (7), the blinds being disposed with fixed orientation and position.
