Abstract
A method for sealing a pipe that conveys gases or liquids, comprising two steps: a first step, which includes a cold plastic deformation of the material that is suitable to impart the chosen shape and reduce the diameter of the pipe to be closed, and a second step, during which the material is brought by friction to a temperature sufficient to render it plastic and amalgamable, so as to provide the actual hermetic closure point. The method is performed by means of an apparatus that includes a tool (2) that is shaped according to the material (7) and the shape to be obtained and can rotate freely about a pivot; the pivot is mounted on a rotating mechanical system that is managed by two controlled axes: a first controlled axis (4), which is suitable to move the pivot of the freely rotating tool (2) at right angles to the rotation axis of the entire system, and a second controlled axis (5), which is suitable to move longitudinally with respect to the rotation axis of the system, so that while the entire system turns the interpolation of the axes allows the freely rotating tool (2) to form different shapes at the end of the pipe. <IMAGE>
