Improvements introduced in the manufacture of tubular fittings called elbows, characterized in that they are achieved by compression and simultaneous dehydration of an aqueous mixture of fibers with binder inside the cavity of a permeable mold that opens on an axial plane, which is closed by the opposite end by fixed parts, and containing a coaxial axis noyo that swells, removed at the end of the operation, the aforementioned noyo, making it rotate around a common axis of curvature and constant with the part of the mold that forms the curve intermediate of the elbow and cooperating piece of the core, and on the other hand by the fact that this rotation of the core is carried out after the extraction of opposite end pieces in the mold to the component elements of the core and that constitute obstacles to the free rotation of this inside the mold at the end of the compression of the elbow.
