Patent number: 8668788Abstract: A handling machine for handling rails, arranged in line immediately downstream of a rolling plant, which allows an optimal clamping of the rail along its longitudinal extension, thus effectively withstanding the deflection and its variations, while allowing a longitudinal movement of the rail caused by thermal shrinkage, thus avoiding damages both to the external surface of the rail and to the handlers. A process of handling the rail is also described, which optimizes moving, positioning along a roller table and maintaining the rail substantially rectilinear during the thermal treatment to which it is subjected.Type: GrantFiled: December 4, 2009Date of Patent: March 11, 2014Assignee: Danieli & C.
