Abstract From the Canadian patent

This invention relates to machining of long profiles, that can be bent, held in place using two clamping arms (10) clamping the section to be machined. According to the invention, the profile (12) does not move during machining and the mobile arms are not used to move the profile in front of the tool; the arms move with the tool to the various locations to be machined. Auxiliary supports (25) are flexible in the plane of the profile and provide sufficient support while enabling the profile to deform as a result of stresses applied to it. Machining is more precise and remaining stresses are reduced.
