<p>The shuttle (10) has flexible radial projections along a longitudinal direction, contacted with an inner wall of a cylindrical tube (124) to be polished when the shuttle is placed inside the tube, where the projections are of disc and helical shape and are made of flexible composite material. The projections have sections forming a series of undulations separated from one another in a longitudinal section of the projections, where a rising height of the undulations is higher than a distance between successive undulations. Independent claims are also included for the following: (1) a method for polishing an inner wall of a cylindrical tube (2) an inner wall polishing device comprising a polishing shuttle.</p> |
